What is our primary use case?

I use this solution for mail exchanges, calendars, and setting up meetings.  

What is most valuable?

The features of Microsoft Exchange Online are very intuitive and well-built, keeping the user experience in mind. The usability and the accessibility are the best aspects of this solution.

What needs improvement?

The SaaS platform performance could be improved. At a previous company, we used this same solution on-premises. The data exchange was much faster compared to the SaaS platform and we sometimes experience lags. 

For how long have I used the solution?

I have used this solution for 15 years.

Provides a secure login and is intuitive but needs to be more user friendly
Pros and Cons
  • "Intuitive and easy to use."
  • "Using this solution is initially quite complicated."

What is our primary use case?

This product provides us with a secure login and enables us to gather information from our users. We are resellers and I'm a key account manager. 

What is most valuable?

The design is intuitive and better than the solution we had previously used. Once it was configured it was very easy to use. 

What needs improvement?

This is a single solution and if it's the first time you've used Exchange, it's extremely difficult to get users onboard because it's much more complicated than you'd have with 365, for example. 

For how long have I used the solution?

We've only just started using it, it's been a week. 

What do I think about the stability of the solution?

The solution is stable. 

What do I think about the scalability of the solution?

The solution is scalable, we have around 100 users. 

How was the initial setup?

The initial setup was complex and took us around two weeks. We deployed in-house; it's in the cloud so there's no maintenance required. 

What other advice do I have?

The problem is that it's a little complicated when you first start using it. It's important to read up about it and figure out whether it's the right solution for you. 

I rate the solution seven out of 10.

Which deployment model are you using for this solution?

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

Great for collaboration and syncing calendars with good reliability
Pros and Cons
  • "The solution has been stable with good performance on offer."
  • "The solution could be a bit cheaper."

What is our primary use case?

We use Microsoft Exchange for sending emails and running calendars. With the calendars, we are able to check other people's calendars and be sure of their availability so that they can deploy solutions. That's what we normally use it for.

What is most valuable?

The solution is great for collaboration purposes. 

The calendar capabilities are great.

The solution has been stable with good performance on offer.

The product can scale. 

What needs improvement?

The solution could be a bit cheaper. 

I'd like it to be more voice-activated and to have more AI so that it becomes easier to use. The world is moving toward more AI and machine learning, and likely they will adopt more of it in the future. 

For how long have I used the solution?

We just migrated to the solution. We've used it maybe for about a year and a half so far. 

What do I think about the stability of the solution?

The solution is very stable and reliable. There are no bugs or glitches. It doesn't crash or freeze. 

What do I think about the scalability of the solution?

I've not had any problem with it personally in terms of scaling. Due to the fact that it's connected, it pulls everything down. I'm able to do whatever is needed of me with it without stress. 

Everybody is using it now in the company. If it was not scalable, I don't believe over 100,000 staff members could be using it without issues. It has to be scalable.

If we want to increase usage, we simply purchase more licenses. 

How are customer service and support?

I've not had any contact with tech support. It's been very stable for me. There has been no need.

How was the initial setup?

I'm not part of the team that does the installation. That said, I know that Exchange should be good in terms of implementation. In the mailing lists that I used to install, the installation was straightforward. If you get your configurations right, it works. It works well without any trouble. This is Mircosoft. I'm sure it's fine to install.

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

You do need to pay a licensing fee in order to access the solution. There are also enterprise agreements where companies would have to agree to a certain level of volume. 

It could be less expensive. If it was, more companies would use it. 

What other advice do I have?

I'm an end-user.

I would recommend the solution to others and rate it at a ten out of ten. It's in the Cloud; people don't need to have anything on-site or to worry themselves with problems any longer. Microsoft takes care of the back end while companies can focus on their day-to-day work and be more productive.
