We have moved from enterprise licenses to educational licenses. Educational licenses have certain benefits and discounts.
What's my experience with pricing, setup cost, and licensing?
The product is very cheap. It is relatively affordable.
What other advice do I have?
If someone plans to use the solution, they must consider the number of users. They must choose the license model depending on their organization. The documentation must be put together in detail, and the right model must be chosen. Overall, I rate the tool a ten out of ten.

Executive Vice President and Global Head of Research and Development at Bqube Global
Secure with good support and an easy implementation
Pros and Cons
- "It's not hard to set up."
- "We'd like to see more integration with other platforms."
What is our primary use case?
We are primarily using the solution for Office 365 and various other Microsoft products. It's used for any integration of any applications. Multiple company domains have been configured on a single exchange. It helps us standardize and consolidate connectivity.
What is most valuable?
We like the standardization we can get across all of our companies. We can put all domains on one exchange. The user can then have one single ID instead of creating five emails for one user.
It scales well.
Technical support is helpful.
It's not hard to set up.
The solution is stable.
The product offers good value for money. After a few years, we have seen an ROI.
What needs improvement?
There are no features that are missing.
We'd like to see more integration with other platforms. We'd like to explore the feature of SSO and Artemis.
For how long have I used the solution?
I've used the solution for more than three years.
What do I think about the stability of the solution?
The solution is stable and reliable. There are no bugs or glitches. It's very stable.
What do I think about the scalability of the solution?
The solution can scale well. It's cloud-based, which makes it very simple. We just have to approach our reseller and add on more licenses. You can have 50 users or 50,000 users, and it will work just as well.
We have about 1,000 or more users on the product currently. We do have plans to increase it to 1,500 by the end of the year.
How are customer service and support?
We may have used technical support previously and were able to resolve any issues within a week. They are very good. They are helpful.
Which solution did I use previously and why did I switch?
I did not previously use a different solution. Past colleagues may have used something else.
How was the initial setup?
The initial setup takes two to four weeks. It's pretty straightforward. We take each domain and consolidate everything on the exchange. We can migrate everything in one go, and usually, we migrate each company each week and migrate one by one, so that end users are not disturbed.
What was our ROI?
We have experienced an ROI after three to four years.
What's my experience with pricing, setup cost, and licensing?
We pay for the solution annually. The price is a bit expensive. However, it offers good value for money. The implementation cost is minimal. Also, now it is on the cloud, we don't have to worry about storage, maintenance, or hardware. The cloud is highly secure, and it helps save us money in the long run.
What other advice do I have?
This is the latest version. We are using the cloud version, and it is constantly updated. We are using all of the standard features that come with the cloud-based product.
This is a very user-friendly enterprise solution. Everything is very secure according to GDPR needs. The product is scalable, and its offering good value for money. Everyone can use it. It's a great product.
I'd rate the solution nine out of ten.

Project Manager at Siren Analytics
Quite convenient access from anywhere but the UI could be improved
Pros and Cons
- "The solution is quite convenient because you can access the web version anywhere."
- "The UI could be improved to look more like the desktop version for ease of use."
What is our primary use case?
Our company used the solution as an alternative to desktops for accessing emails remotely. It is a front-end email application that can be accessed from the web.
The solution allowed us to create new emails, collaborate via online surveys, and get feedback from a group of engineers on a specific items. We had 2,000 users across our company.
The solution more or less is an online collaboration tool.
What is most valuable?
The solution is quite convenient because you can access the web version anywhere. You aren't tied to a company-provided laptop where you have your Outlook desktop.
What needs improvement?
The UI could be improved to look more like the desktop version for ease of use.
For how long have I used the solution?
I used the solution all the time as an end user with my prior employer.
What do I think about the stability of the solution?
The solution is stable with no issues.
What do I think about the scalability of the solution?
The solution is scalable because it is on the Microsoft cloud. The sky is the limit.
How are customer service and support?
As an end user, I contacted our internal support team. They actually handled reaching out to Microsoft's technical support. The process didn't take a lot of time and was quite transparent. We received feedback within 24 hours.
How was the initial setup?
The solution is cloud-based and accessed via a website so there is no setup. You just point to the URL, provide any extensions, and log in to the solution.
What about the implementation team?
We implemented the solution in-house.
Our IT department deployed by installing exchange server and enabling a shared configuration item. This allowed all users to access the solution via the web.
Deployment shouldn't take more than two hours because you just enable the web for the online exchange. Then you share a link or the URL so users can access the solution.
What was our ROI?
Our company achieved ROI by using the solution.
What's my experience with pricing, setup cost, and licensing?
The pricing is based on a yearly contract and a floating license option is offered.
What other advice do I have?
I strongly recommend using the solution.
Which deployment model are you using for this solution?

Product Manager at PayU Payments Private Limited
Easy to use, and straightforward deployment, but is not stable
Pros and Cons
- "The solution is scalable."
- "The stability of the solution has room for improvement."
What is our primary use case?
The primary use case of the solution is for email and SharePoint.
How has it helped my organization?
We are beginning to explore Office 365 Online Exchange and Azure, which are part of Microsoft 365. We intend to create our Active Directory and Domain Controller on Azure and integrate OnTime Active Directory with Azure Active Directory.
What is most valuable?
I haven't encountered any downtime with Exchange Online so far. Last week, the entire Azure portal experienced an outage, which caused some disruption, but thankfully, we haven't had any issues with 365 yet.
What needs improvement?
The stability of the solution has room for improvement.
For how long have I used the solution?
I have been using the solution for over four years.
What do I think about the stability of the solution?
I give the stability a seven out of ten.
What do I think about the scalability of the solution?
The solution is scalable.
We have thousands of people using Microsoft Exchange Online.
How are customer service and support?
We have a limited amount of time to contact tech support, but we usually communicate with the vendor. If I have an issue, our Microsoft partner can help us with problem-solving.
Which solution did I use previously and why did I switch?
We previously used Google G Suite before switching to Microsoft Exchange Online.
How was the initial setup?
The initial setup is straightforward.
What about the implementation team?
The implementation was completed in-house with the help of our Microsoft partner.
What was our ROI?
We have seen a return on investment since we are taking advantage of the license and Microsoft Exchange Online's useful features.
What's my experience with pricing, setup cost, and licensing?
The cost of our annual license for the solution is moderate. I would give the cost a five out of ten.
What other advice do I have?
I give the solution a seven out of ten. Microsoft Azure has experienced outages at times, but it can be comparable to Amazon Web Services (AWS).
I strongly suggest using Microsoft Office Exchange due to its ease of use and maintenance, as well as its increased reliability and added security features.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

L3 Technical Support Engineer at SV Gaming Limited
Useful sandbox feature; quite cheap
Pros and Cons
- "It is a fantastic solution."
- "In the next release, I would like to see more features added to the security of the solution."
What is our primary use case?
The primary use case for Exchange Online is managing users and their mailboxes, resources, and contacts. We also use it to manage email communication within and outside the organization.
How has it helped my organization?
Exchange Online has helped us properly manage email communications in the company and also from employees to other users outside the company. Microsoft has deployed a lot of newer features on Exchange Online that have helped improve security, email management, email trace, mail flows, and all else. This has been very helpful for us.
What is most valuable?
The features I find the most valuable are the rules, the mail flow, the reports, and the shared mailbox. I most appreciate the shared mailbox feature.
What needs improvement?
I think Microsoft could add more security features in terms of managing spam emails, because for us as an organization, we've had to deploy that trace to complement the Exchange Online security feature.
In the next release, I would like to see more features added to the security of the solution.
For how long have I used the solution?
I have been using Microsoft Exchange Online for over three years now.
What do I think about the stability of the solution?
I would rate the stability of this solution a 10, one a scale of one to 10, with one being not stable and 10 being very stable.
What do I think about the scalability of the solution?
I would rate the scalability of this solution a 10, one a scale of one to 10, with one being not scalable and all and 10 being very scalable.
We plan on increasing the usage of this solution in the future. As we increase the number of our employees, we also increase the usage of Exchange Online.
We currently have about 700 users and above.
How are customer service and support?
I would rate their customer service a 10, on a scale of one to 10, with one being very poor and 10 being very responsive.
How would you rate customer service and support?
Positive
How was the initial setup?
I would rate the initial setup a 10, on a scale of one to 10, with one being very complex and 10 being very straightforward. It was really straightforward.
What was our ROI?
We see a whole lot of return on investment.
What's my experience with pricing, setup cost, and licensing?
I would advise being aware of the organization's requirements. Also, an in-house technical person that can help in terms of managing is a necessity, because Exchange Online requires a continuous management process. The solution is not one that can just be deployed one-off and let go; it has to be continuously managed. Also, Exchange Online is quite cheap.
What other advice do I have?
Overall, I would rate Microsoft Exchange Online a 10, on a scale of one to 10, with one being poor and 10 being excellent. It is a fantastic solution.

Office 365 and Exchange Administrator at Vvolve management consultants
A cloud based messaging platform that delivers email, calendar, contacts, and tasks
Pros and Cons
- "One of my favourite features is the Microsoft Calendar, which we use for booking appointments, scheduling calls, and managing resource rooms and devices. The Online Mailbox feature is also crucial because it allows us to communicate effectively within and outside the organization, contributing to our business growth."
- "In terms of areas for improvement, I think Microsoft could enhance security. Right now, there are limited options for security within Exchange Online, and much of it relies on third-party security and compliance tools. I'd like to see more security features directly integrated. One specific area that needs improvement is the configuration of SMTP for third-party applications. It's challenging to manage without an on-premise SMTP server, and this is an issue many organizations face, including ours. If Microsoft could offer better SMTP configuration for third-party applications within Exchange Online, it would greatly benefit us."
What is our primary use case?
In our organization, we use Microsoft Exchange Online to send and receive emails, schedule meetings and appointments, manage calendars, book rooms, and manage resources. It's an essential tool for us. We implemented Exchange Online to support our users by managing licenses and creating new mailboxes, shared mailboxes, distribution groups, M365 groups, and security groups. It also helps us manage calendar permissions and other tasks.
How has it helped my organization?
In my organization, we initially used Microsoft Exchange Online just for sending emails, but now, with the integration of Microsoft Copilot, we've seen significant improvements. Copilot helps analyze emails and provide analytics, making it an essential feature for us. It's been a great addition, and our management finds it very valuable.
What is most valuable?
One of my favourite features is the Microsoft Calendar, which we use for booking appointments, scheduling calls, and managing resource rooms and devices. The Online Mailbox feature is also crucial because it allows us to communicate effectively within and outside the organization, contributing to our business growth.
What needs improvement?
In terms of areas for improvement, I think Microsoft could enhance security. Right now, there are limited options for security within Exchange Online, and much of it relies on third-party security and compliance tools. I'd like to see more security features directly integrated. One specific area that needs improvement is the configuration of SMTP for third-party applications. It's challenging to manage without an on-premise SMTP server, and this is an issue many organizations face, including ours. If Microsoft could offer better SMTP configuration for third-party applications within Exchange Online, it would greatly benefit us.
For how long have I used the solution?
I’ve been working with Microsoft Exchange Online for the past four and half years across different organizations, including SEL Technology and CCS, and now at my current company. I’m a Microsoft Office 365 administrator working at a US-based multinational company. I’m an IT professional and a subject matter expert for Microsoft Exchange Online. As a technical support engineer for level two and level three, I provide customer support for various Outlook-related issues such as delegate access, mailbox queries, permissions, creating new mailboxes, and managing SMBL.
What do I think about the stability of the solution?
In terms of stability, I'd give it a nine because it's very stable compared to other messaging systems.
What do I think about the scalability of the solution?
For scalability, I also rate it a nine since it's highly scalable.
How was the initial setup?
It was easy to implement. Microsoft provides all the necessary documentation; I'veconfigured it myself for my organization without any issues. It's simple enough that even a quick learner can implement it. Setting it up takes about an hour or two, depending on the configuration, but it can be done within a day for a new organization in the cloud.
What's my experience with pricing, setup cost, and licensing?
The pricing for Microsoft Exchange Online is quite reasonable, in my opinion. Many licensing options are available so that we can choose based on the customer's needs. For example, if a customer only requires mailbox features, we can recommend Plan One or Plan 2. We can suggest an E3 or E5 license if they need the entire Office suite. There are also premium subscriptions for enterprise customers, offering additional security features. Overall, I don't find the pricing costly because Microsoft provides many features and security capabilities, making it reliable for all customers, depending on their requirements.
What other advice do I have?
Overall, I would recommend Microsoft Exchange Online to others because of its easy implementation and the range of features it provides at a reasonable price point. It includes everything needed without requiring third-party vendors, making it highly efficient. However, due to the SMTP configuration issues, I would rate it an eight out of ten overall.
Which deployment model are you using for this solution?
Public Cloud

Which other solutions did I evaluate?
My company chose Microsoft Exchange Online over other products since we have a partnership with Microsoft. For our company's business uses, Microsoft helps save costs and offers good support.
What other advice do I have?
The feature of Microsoft Exchange Online I found to be the most beneficial for team collaboration stems from the integration capabilities. Microsoft Exchange Online can integrate with products like Microsoft Teams or Windows Live.
I have seen that Microsoft Exchange Online's dashboard ensures the aggregation of all the integrated items in a single interface. I think my company has to order Microsoft Teams and apply for it separately to be used on a product like Microsoft Exchange Online.
The security and compliance features of Microsoft Exchange Online have impacted our company's business operations as it is a good tool for business needs, and I haven't seen any major issues with it in any of the items provided. I have also not had any negative reviews or complaints about the product from our company's teams.
I use the solution's calendar functions for my scheduling needs. but I don't know how it offers any support.
The tool's integration capabilities were used for the benefit of the management of the areas attached to the solution from a single place.
I rate the overall tool a nine out of ten.

Used for emails and provides integration with other services for shared calendars

- "The solution’s technical support could be improved."
What is our primary use case?
We use Microsoft Exchange Online for emails.
What is most valuable?
The most valuable feature of the solution is its integration with Microsoft Outlook and Microsoft Teams for shared calendars.
What needs improvement?
The solution’s technical support could be improved.
For how long have I used the solution?
I have been using Microsoft Exchange Online for two to three years.
What do I think about the stability of the solution?
We haven't faced any issues with the solution's stability.
I rate Microsoft Exchange Online an eight out of ten for stability.
How are customer service and support?
The solution's technical support is sometimes helpful and sometimes useless. It depends on the agent that is working on your case.
I rate the solution’s technical support a six or seven out of ten.
How would you rate customer service and support?
Neutral
Which solution did I use previously and why did I switch?
I previously worked with the IBM Domino mail system. Compared to the on-premises model of Microsoft Exchange Online, the IBM Domino mail system's maintenance and administration upgrades were less complicated.
How was the initial setup?
It wasn't difficult to migrate the solution from on-premises to the cloud. It took us around one week to migrate from on-premises to the cloud because we don't have that many mailboxes.
What's my experience with pricing, setup cost, and licensing?
We are Microsoft partners. We bought some licenses, and some are within our package or partnership with Microsoft.
What other advice do I have?
Earlier, we had the solution on-premises, and then we migrated to the cloud. The solution helped with the planning and time management within our organization by providing everything that Outlook offers to end users, including email and calendar.
The solution does not provide 100% security, and some emails are still detected as malicious by our other endpoint security solution. Microsoft Exchange Online does not require any maintenance from our side.
Overall, I rate the solution an eight out of ten.

Managing Director at ProQuanta
A stable solution for managing suites with a collaboration feature
Pros and Cons
- "One of the important features is the collaboration tool used in Office 365. The security and DLP mechanisms are also quite good."
- "The solution’s pricing could be better."
What is our primary use case?
We use the solution to manage calendars and the entire online and on-premises suite. It is used in large corporate banks.
What is most valuable?
One of the important features is the collaboration tool used in Office 365. The security and DLP mechanisms are also quite good.
What needs improvement?
The solution’s pricing could be better.
For how long have I used the solution?
I have been using Microsoft Exchange Online as a reseller for three to four years.
What do I think about the stability of the solution?
The collaboration speed has some issues, but it is stable.
I rate the solution’s stability an eight-point five out of ten.
What do I think about the scalability of the solution?
The solution is scalable. When you reach certain volumes, the default limits on the packages essentially allow you to use the full spectrum anyway.
The solution’s packaging makes it difficult to scale to the enterprise level without significantly upgrading the packages and negotiating higher limits on certain things, such as API calls, to accelerate data transfer.
Around 3000 users are using this platform.
I rate the solution’s scalability a nine out of ten.
How are customer service and support?
Microsoft technical support is making some improvements, but it can still be time-consuming to get an answer to a basic question. I often find it easier to troubleshoot the problem myself.
How was the initial setup?
The initial setup is straightforward and takes around a week to complete.
Exchange Online deployments can be complex, especially when migrating existing data from on-premises to the cloud. Much planning and preparation is involved, and the process can be lengthy.
What's my experience with pricing, setup cost, and licensing?
The product is expensive and has an annual subscription.
Which other solutions did I evaluate?
It's difficult to compare Exchange Online to other solutions because of its unique feature set and collaboration capabilities. For example, Google SaaS is quite limited compared to Exchange Online.
What other advice do I have?
We require a full-time team of four or five engineers across different divisions to look after this solution.
I recommend this solution. You’ll find it difficult to find a better solution with all the same features at the same price point. Most other competing solutions don't have the same feature set for the price.
Overall, I rate the solution an eight out of ten.
