The most valuable features of the solution are the security of the email flow, the primary security, having a dedicated, consultative space where if I send an email from a billing app or from a browser or anywhere, it gets stored in consultative space, and some of the end users features such as Word solution.

The solution
The solution doesn't require any maintenance. The solution is a cloud platform and everything is taken care of by Microsoft, so there is no maintenance required. It's maintenance-free.
I recommend the solution. As soon as you know what your needs are, you can go ahead with Microsoft Exchange Online. You don't need any demonstration of features, and you don't need to do any POCs.
I think the solution is pretty reasonable in what it does. In terms of mobile applications, that is Microsoft Outlook for Android and iOS integration, which can make some integration to Microsoft Teams application, which is already prospected in the desktop application. If they can have it in mobile application also, that would be good. But as a solution, I couldn't think of any new features that are required presently.
Which deployment model are you using for this solution?
Private Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Microsoft Azure

CDO at SGROUP
Convenient, easy to install, and scalable when deployed on the cloud, but has too many products integrated with it that it has now lost focus
Pros and Cons
- "What I like about Microsoft Exchange Online is that it's a very convenient solution because it's part of the Microsoft business suite. This is the first email service I've used that lasted for many years, and I'm still using it because it's very convenient and it's suitable for my needs. Microsoft Exchange Online is the best product in the world for me because I don't remember any other service that's so well-accepted."
- "What I don't like about Microsoft Exchange Online is too much integration because now it has many services connected to it. In the beginning, it was just email, and now it's also Teams and Visio, and many other services which I don't like. Microsoft Exchange Online should focus on one service. The product now lost focus, and this is its area for improvement. I would also like more freedom in choosing to use just one service, for example, just Microsoft Exchange Online, which means I don't need Teams or any other Microsoft product or service there. Right now, all services are either in the Microsoft Office suite, or there are more products or services integrated with Microsoft Exchange Online, and I'd like to just focus on one."
- "What I don't like about Microsoft Exchange Online is too much integration because now it has many services connected to it."
What is our primary use case?
We're using Microsoft Exchange Online for our emails.
What is most valuable?
What I like about Microsoft Exchange Online is that it's a very convenient solution because it's part of the Microsoft business suite. This is the first email service I've used that lasted for many years, and I'm still using it because it's very convenient and it's suitable for my needs.

What I don't like about Microsoft Exchange Online is too much integration because now it has many services connected to it. In the beginning, it was just email, and now it's also Teams and Visio, and many other services which I don't like.

For how long have I used the solution?
I've been using Microsoft Exchange Online for more than ten years.
What do I think about the stability of the solution?
Microsoft Exchange Online is a stable product, in particular, when it's on the cloud. It's stable when it's dependent on the cloud, but if it's deployed on-premises, Microsoft Exchange Online is not stable.
It's a very old product with the same code, even on Windows. Nothing's changed, and my company is using Windows NT for Microsoft Exchange Online with Unix as the code.
What do I think about the scalability of the solution?
Microsoft Exchange Online is a scalable solution.
How are customer service and support?
We haven't used the technical support for Microsoft Exchange Online.
Which solution did I use previously and why did I switch?
Microsoft Exchange Online is the first service I've used, and all the new services in the market are a little bit different from this solution. Microsoft is a very old company, and almost all of my colleagues started with Microsoft products, so it's just natural to continue using Microsoft Exchange Online.
How was the initial setup?
Microsoft Exchange Online is easy to install.
What's my experience with pricing, setup cost, and licensing?
There is a license for Microsoft Exchange Online and I have information on that, but there have been so many changes to the licensing and it's a completely different story nowadays. Microsoft has been pushing users to buy a package of products under one license. Users are becoming more dependent on Microsoft rather than independent, that you can't decide anymore, and from my point of view, that is bad.
Which other solutions did I evaluate?
My company evaluated Qualitas, Unix, HP, and IBM.
What other advice do I have?
In my company, Microsoft Exchange Online is deployed both on the cloud and on-premises.
More than two thousand people use Microsoft Exchange Online in my company of four thousand employees.
At the moment, there's no plan of increasing usage of the product because of the current crisis.
In terms of whether I would recommend Microsoft Exchange Online to others, with the integration it has, it depends on the focus of the company. For small markets, Microsoft Exchange Online is "too big" because it has a lot of services and you'll be paying for services provided in the package, with some you don't get to use. For end users, this would be difficult, but for companies, especially bigger ones that would have a choice, Microsoft Exchange Online is a good product. My recommendation would depend on the case because every user is different, for example, the purpose is different, the business is different, etc.
My rating for Microsoft Exchange Online is seven out of ten.
Which deployment model are you using for this solution?
Hybrid Cloud

Assistant Manager Technical at Ironbridge Systems (Pvt.) Limited
Features like SharePoint Online allow for collaboration between our team members
Pros and Cons
- "We also create technical presentations, so most of the time we are dealing with MS Word and Excel. Sometimes, we also use Visio for diagramming. Our overall experience is good."
- "Overall, technical support is very good."
- "They should tighten their cloud security."
What is most valuable?
We use SharePoint Online for the collaboration of our team and for other desktop applications we are using in-house.
We also create technical presentations, so most of the time we are dealing with MS Word and Excel. Sometimes, we also use Visio for diagramming. Our overall experience is good.
What needs improvement?
They should tighten their cloud security. If you are using Microsoft Office 365, the responsibility of backup is not on the part of Microsoft. It is on the part of the customer. Microsoft Office should give some kind of built-in solution with the Office 365 subscription regarding the backup of their online mailboxes.
For how long have I used the solution?
My company has been a Microsoft Gold partner for the last 12 years. As soon as we became a Gold partner, we started to use Office 365.
What do I think about the stability of the solution?
It's stable.
What do I think about the scalability of the solution?
We can have different plans. If we are scaling, then obviously we can go for the enterprise plan and add an unlimited number of users to our Office 365 plan.
How are customer service and support?
Overall, technical support is very good. My colleagues reached out to Microsoft technical support many times for queries. They are very responsive.
How was the initial setup?
Setup was really simple. We migrated our customers from a different platform to Microsoft Office 365. There is a separate technical team. I designed the solution only.
What's my experience with pricing, setup cost, and licensing?
They have raised their prices, and obviously, it hits our customers. Some of them are deciding to step back from Office 365. For customers who have bought the annual subscription, they are moving to the monthly subscription.
What other advice do I have?
I would rate this solution 8 out of 10.
I would recommend Office 365. It's a global product, and overall they have a larger footprint in the world. We're a Microsoft Gold partner, so as soon as the customer moves to Office 365, obviously our business will also grow.
