Quick setup, useful online archiving, and highly scalable
Pros and Cons
  • "The most valuable feature of Microsoft Exchange Online is if you have people that are geographically distributed from each other is good. For example, if you have people in the United States, Europe, Africa, Asia, and Australia, having an online solution works best because then you can reach the scale of the data centers that are available by Microsoft. Additionally, if you're only going to have two to three people using the solution the cost is a lot less than having an onsite server and licensing. It is highly beneficial in these areas."
  • "The support from the vendor is fine. However, it could be faster, and some of the agents could be more knowledgeable, but it is a large solution, there's a lot of information that the agents have to work with. I can't always expect when I get connected to the first-level agent that they will know absolutely everything. Sometimes there's no replacement for pure experience."

What is our primary use case?

Microsoft Exchange Online is used for emails and it does a fantastic job. 

The only reason why you would choose an online solution is the company that you're working at is they do not want to have an onsite server. The companies that want something on-site would choose the on-premise version.

What is most valuable?

The most valuable feature of Microsoft Exchange Online is if you have people that are geographically distributed from each other is good. For example, if you have people in the United States, Europe, Africa, Asia, and Australia, having an online solution works best because then you can reach the scale of the data centers that are available by Microsoft. Additionally, if you're only going to have two to three people using the solution the cost is a lot less than having an onsite server and licensing. It is highly beneficial in these areas.

The online archiving option works well. If you have a lot of emails and you want to keep them indefinitely, then you can use the online archive. It's available permanently and you can store quite a bit of email inside it.

For how long have I used the solution?

I have been using Microsoft Exchange Online for approximately four and a half years.

What do I think about the stability of the solution?

The stability of the solution is good. I've only had an issue with it once or twice, but that was due to undersea cable damage.

What do I think about the scalability of the solution?

Microsoft Exchange Online is highly scalable.

We have a lot of users using this solution.

How are customer service and support?

The support from the vendor is fine. However, it could be faster, and some of the agents could be more knowledgeable, but it is a large solution, there's a lot of information that the agents have to work with. I can't always expect when I get connected to the first-level agent that they will know absolutely everything. Sometimes there's no replacement for pure experience.

I rate the support from Microsoft Exchange Online a three out of five.

How would you rate customer service and support?

Neutral

How was the initial setup?

The initial setup of the cloud version is similar to the on-premise version. You can have a straightforward or semi-complex deployment. Cloud deployments do not become as complex as the on-premise version, but they can, depending on how it is used. 

The deployment of the solution only takes five minutes. It is very useful when deploying from scratch. As soon as you have the domain up and running it is complete and ready to go.

What's my experience with pricing, setup cost, and licensing?

The license for the solution is cheap, but it could be more affordable in the long term.

What other advice do I have?

We have one level two or level three engineer that does the deployment and maintenance of the solution. The online version does not require a lot of people to run it.

I recommend this solution to others and they will not regret it. They should not use other solutions.

I rate Microsoft Exchange Online a nine out of ten.

Which deployment model are you using for this solution?

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.

The tool has diverse functions and excellent support
Pros and Cons
  • "Microsoft has many consultants who can provide support."
  • "It is tricky to integrate Microsoft Exchange Online if you are in an infrastructure provided by other vendors."

What is our primary use case?

I work for civil ministries, and we exclusively use Microsoft products because we get them for a low price.

I handle security with Fortinet, and I run virtualization with Citrix. Those are my main tasks.

What is most valuable?

Microsoft has many consultants who can provide support.

What needs improvement?

Some of the Microsoft implementations of protocols are far from standard. They make their own standards, and you're out if you can't convert to them. With other Unix-based solutions, we had more flexibility to react to special problems we needed to solve. We can only solve the problem now if the problem is solvable with Microsoft.

Similarly, it is tricky to integrate Microsoft Exchange Online if you are in an infrastructure provided by other vendors. We have had an alternative solution to Exchange since 2016, and if we had problems, it was never a problem with Microsoft. It was a problem with the alternative product. The problem is that Microsoft has a standard, and you need to stick to it.

Even if the reason for the problems is Microsoft, the SMTP stack in Exchange is far from the RC of SMTP. If the alternative solution makes extensions to DNS for their active directory and if you use an RC DNS server, you would have problems with some of the records that Microsoft produces. They are not replicated. If you begin with Microsoft, you make everything Microsoft. It is difficult to mix Microsoft with other vendors or with other products. And you get less support if you want to choose a solution other than Microsoft.

Moreover, Exchange Online should work on integration with other services like Teams because when they work together, you gain benefits that other companies might not be able to give you.

For how long have I used the solution?

I have been using Microsoft Exchange Online since 2012, and we will use it in the future.

Which solution did I use previously and why did I switch?

We formerly worked with Unix-based mail servers. The positive side is that you're flexible. You could use different hardware. You get limited with Microsoft.

What's my experience with pricing, setup cost, and licensing?

Microsoft solutions are expensive.

What other advice do I have?

I prefer to use solutions like LibreOffice since they are free and cheaper, but our partners might have problems reading our data, and we would face difficulties cooperating.

The main problem with Microsoft products is that we get very dependent on them. Until 2016, I had to make decisions for the budget for the Southwest of Germany, and when you work with Microsoft, your budget is fixed to them, and you lose your ability to work with other solutions. That was a bad situation for us.

If you don't plan to use other solutions in the future, it's a good product. Otherwise, you have to be prepared that some problems may arise. Once you get married to Microsoft, it's a fierce divorce if you want to leave. I rate the solution an eight to nine out of ten.

Easy to set up with good pricing and good access
Pros and Cons
  • "Technical support is helpful."
  • "We'd like to have the ability to recall emails on the web. I'm not sure if that is available yet."

What is our primary use case?

The solution is basically for access and it provides the ability to just receive and send emails. It also works with calendars and contacts and all of that.

What is most valuable?

The solution works very well. It's one of the best options available. The access it provides is good. 

It has an easy initial setup. 

Technical support is helpful.

It is scalable.

The solution is quite stable. 

It has okay pricing. 

What needs improvement?

We'd like to have the ability to recall emails on the web. I'm not sure if that is available yet.

I haven't used the solution for too long and need more time to see if other improvements are needed.

The cost could be a bit lower.

We've had clients complain about some aspects of Microsoft Bookings. It would be great to have an opinion platform back on Bookings. 

For how long have I used the solution?

I've been working with the solution for six months. 

What do I think about the stability of the solution?

The solution is stable. The only thing that is not so stable is Microsoft Teams. However, Exchange has good reliability. It doesn't crash or freeze. 

What do I think about the scalability of the solution?

I love the scalability. I like that I can start wherever I am and scale up or down. I love the flexibility it gives us.

We have about 50 people on the solution presently. 

How are customer service and support?

Technical support is great. I've raised some requests, and they were helpful and responsive. 

Which solution did I use previously and why did I switch?

We did not previously use a different solution. 

How was the initial setup?

I took part in the implementation process. The initial setup is pretty straightforward and simple. 

The deployment didn't take more than an hour. 

We have two administrators that are global admins. We have one admin that is specifically for Exchange. 

What's my experience with pricing, setup cost, and licensing?

The pricing is fine. I've discussed this with customers, and they have found the price point to be fair. When you compare it to others, like Google, it is competitive. If it could be lower, of course, it would be ideal.

The solution costs $12 to $16 per user per month. 

What other advice do I have?

I currently support Microsoft products. I don't sell Microsoft. They also have my test environment, where I test a few things.

Everything is available in the documentation. It's a great solution. Everything you need is there.

Overall, I'd rate the solution nine out of ten. There's always room to improve still. 

Which deployment model are you using for this solution?

Public Cloud

Good documentation, excellent support, and an easy initial setup
Pros and Cons
  • "The solution generally works well. We can send and receive emails just fine."
  • "The pricing could be a bit lower."

What is our primary use case?

We primarily have it for our customers. We primarily use the solution with mobile access, and it's just for having the ability to send and receive emails. It also works with calendars and contacts. 

What is most valuable?

The solution generally works well. We can send and receive emails just fine. 

It is useful and easy to use. 

The initial setup is straightforward. 

It's scalable.

The solution is stable.

Technical support is great.

The solution offers great documentation. 

What needs improvement?

We'd like to have the ability to recall emails. 

I've just used it for six months and am still working to understand the general landscape.

The pricing could be a bit lower. 

Certain items have been removed from Mircosoft Booking. They should re-add the capabilities it had before. 

For how long have I used the solution?

I've been using the solution for six months at this point. It's been less than a year. 

What do I think about the stability of the solution?

The stability of this solution is pretty good. We do find, however, that Microsoft Teams is unstable. Exchange, so far, has been great. 

What do I think about the scalability of the solution?

This solution is definitely scalable. We haven't had any issues at all. I love that I can start with what I actually need and scale up or down as needed from there. 

Right now, we have about 50 people on the solution. 

How are customer service and support?

Technical support is great. We're happy with its capabilities. There is also useful documentation that can help users understand the solution. 

Which solution did I use previously and why did I switch?

We are not using any other solutions. 

How was the initial setup?

The setup is pretty straightforward. It's not overly complex. It just took about an hour to set up everything. We simply had to go through some documentation. After we did that, it was very easy.

We have two administrators that can handle the management. They are global Microsoft admins. We also have an Exchange admin specifically. 

What's my experience with pricing, setup cost, and licensing?

The pricing is fine. I've had similar conversations with my customers, and we've found the cost is fair. However, if it could be lower, that would be a plus. 

The cost is around $12 to $16 per user.

What other advice do I have?

I'm an end user. We also currently support Microsoft products. 

Everything is available in the documentation, and there is great support. It's worth the price, and other users would enjoy having it.

I'd rate the solution nine out of ten.

It's easy to deploy and scale, but it can be complex to incorporate different departmental requirements into one platform
Pros and Cons
  • "Exchange Online is consistent. It's easy to deploy and scale out to all of our organizations."
  • "The efficiency could improved."

What is our primary use case?

We use Microsoft Exchange Onlne for communication, collaboration, and some project management tasks.

What is most valuable?

Exchange Online is consistent. It's easy to deploy and scale out to all of our organizations.

What needs improvement?

The efficiency could improved.

For how long have I used the solution?

I have been working with Exchange Online for more than 10 years.

What do I think about the stability of the solution?

Exchange Online must be reliable and available for our operations.

How was the initial setup?

It can be complex to incorporate the unique requirements of each division into a single platform to meet all of the requirements. It's not hard to maintain Exchange Online, but you need an expert on your team and some outside help from the vendor.

What other advice do I have?

I rate Microsoft Exchange Online seven out of 10.

Hosted messaging solution used in addition to Office 365 offering remote access to mailboxes
Pros and Cons
  • "This solution makes it very easy to receive and detect problems about the mail flow and offers very good reporting. In general, it's very easy to manage the organization's mailboxes."
  • "When we need to purchase additional licenses for additional users, the process is slow."

What is our primary use case?

We use this in addition to Office 365 in order to have our user mailboxes on the cloud.

What is most valuable?

From a user's perspective, this solution enables them to access to their mailbox from anywhere and their mailbox size is as big as 100 gigabytes so they never run out of space. 

This solution makes it very easy to receive and detect problems about the mail flow and offers very good reporting. In general, it's very easy to manage the organization's mailboxes.

What needs improvement?

When we need to purchase additional licenses for additional users, the process is slow. 

We would like to have a single point of view or pane where we can manage all of our infrastructure. 

For how long have I used the solution?

I have been using this solution for six years. 

What do I think about the stability of the solution?

This is a stable solution. I would rate it a four out of five. 

What do I think about the scalability of the solution?

This is a scalable solution. I would rate it a five out of five. 

How was the initial setup?

The deployment of Exchange Online only was very easy and was completed within a week. The full setup and migration of on cloud and on-premises infrastructure is still in progress but this is not due to difficulty. 

What was our ROI?

The return on investment is very good. I would rate it a five out of five in this regard. 

What's my experience with pricing, setup cost, and licensing?

The pricing for this solution is good. We renew our contract every three years. I would rate the pricing for this solution a three out of five. 

What other advice do I have?

I would rate this solution a nine out of ten.

Helps reduced IT operations, scalable, and simple setup
Pros and Cons
  • "The most valuable feature of Microsoft Exchange Online is it helps the IT department with problems."
  • "Microsoft Exchange Online can improve message delivery. There are times we receive a message that the email failed to be delivered, and there is no reason given. We sometimes have emails that are flagged as spam that are not. We cannot do anything about it because it's not managed by us, it's managed by Microsoft."

What is our primary use case?

We use Microsoft Exchange Online for email, such as sending and receiving emails. Our critical people are on the cloud and our non-critical people are on the premise.

What is most valuable?

The most valuable feature of Microsoft Exchange Online is it helps the IT department with problems.

What needs improvement?

Microsoft Exchange Online can improve message delivery. There are times we receive a message that the email failed to be delivered, and there is no reason given. We sometimes have emails that are flagged as spam that are not. We cannot do anything about it because it's not managed by us, it's managed by Microsoft.

For how long have I used the solution?

I have been using Microsoft Exchange Online for approximately two years.

What do I think about the stability of the solution?

We can experience some glitches but this could be the fault of our ISP and not the Microsoft Exchange Online. Other than this experience it has been stable.

What do I think about the scalability of the solution?

The scalability of Microsoft Exchange Online is good as long as you are paying for the approximate usage.

We have approximately 800 people using this solution in our group. We have many types of users, such as managers and architects.

How are customer service and support?

I have not used the support from Microsoft Exchange Online.

How was the initial setup?

The initial setup of Microsoft Exchange Online is very simple.

What's my experience with pricing, setup cost, and licensing?

The cost of Microsoft Exchange Online is approximately $4 to $36 per user. They do not give a discount which is not good. The solution is expensive if you have 800 to 1,000 users. They should give discounts when you have a lot of users.

Which other solutions did I evaluate?

I evaluated Microsoft Exchange on-premise, and it has a lot of glitches and needs a lot of maintenance. I chose Microsoft Exchange Online to cut this risk on our day-to-day operations for organizational communication with clients. We decided to move forward with migrating most of our users from Microsoft Office 365 or Microsoft Exchange Online, where those critical users would be not in a risk position in case anything happened on the Microsoft Exchange on-premise.

What other advice do I have?

I chose to use Microsoft Exchange Online because of the disaster recovery, and clustering, and to make sure that our users are eligible for the business continuity process.

This solution is good if you have a critical business, you don't want to have any kind of down communication, you are located in multiple regions, your IT team is not large enough to maintain an Exchange on-premise servers or you don't have the large infrastructure to have clusters.

I rate Microsoft Exchange Online a nine out of ten.

Which deployment model are you using for this solution?

Hybrid Cloud
