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.

Useful mail flows, stable, and simple installation
Pros and Cons
- "All of the Microsoft Exchange Online is very useful, such as the sections, the information protection, and the mail flows."
- "The solution could improve with the integrations with some of the known applications is still not possible, there must be more connectors."
What is our primary use case?
We use Microsoft Exchange Online for emails and communication.
What is most valuable?
All of the Microsoft Exchange Online is very useful, such as the sections, the information protection, and the mail flows.
What needs improvement?
The solution could improve with the integrations with some of the known applications is still not possible, there must be more connectors.
There should be a feature when sending the emails it pops up and gives the confirmation of the real details when you are sending them out outside. There's an option for the alerts, but there's no double-check. We cannot double-check it or re-confirm it again. This option would be nice to have.
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?
I have found Microsoft Exchange Online to be stable. I have not had any issues.
What do I think about the scalability of the solution?
Microsoft Exchange Online is scalable.
How are customer service and support?
I have not needed the support.
Which solution did I use previously and why did I switch?
I have used Gmail previously, but I like Microsoft products better. The options and features are already at the granular level.
How was the initial setup?
The installation is simple.
What about the implementation team?
I did the implementation of the solution myself.
What's my experience with pricing, setup cost, and licensing?
I am using Office 365 and Microsoft Exchange Online comes as the package. It cost approximately $13 per month.
What other advice do I have?
We have a lot of connectors with Office 365, and it's integrated with Microsoft technologies already. Additionally, there is integration with other third parties solutions. It's a good product.
I rate Microsoft Exchange Online a ten out of ten.
Which deployment model are you using for this solution?
Public Cloud

Solutions Architect at a comms service provider with 1,001-5,000 employees
It is a solid product, without a doubt.
Pros and Cons
- "The reliability factor is high."
- "Stability has increased exponentially since 2010."
- "It should integrate better with social media formats."
What is our primary use case?
Our primary use case for this solution is as a messaging solution for our company.We use it both for internal and external messaging services.
How has it helped my organization?
There are two aspects to the improvement of our organization. First, is the data reliability, the ability for an administrator to provide data which has been in the user's mailbox. For example, if someone lost the email because of inadvertently deleting the emails, or anything, any object inside the inbox, whether it's a contact or a folder or an email. The admin can actually go and restore that information quite easily, rather than any other solution.
Second, the mobility of the solution helps solve issues with information access across varied platforms. This has helped us if there are issues concerning emails that must be recovered due to legal issues, and the like.
What needs improvement?
It would be nice for SharePoint to integrate with other social media platforms like Twitter, WhatsApp and Facebook. If all of these channels could perform together, that would be great.
In addition, there should be a feature of informing a user if the video, or large file someone would like to attach is too big a file. Instead of bouncing back to the writer, it should warn the user with a message that they cannot send a file over 30, 40 or 50 MB. It could be more engaging with the user, and this will make the platform more user-friendly.
For how long have I used the solution?
More than five years.
What do I think about the stability of the solution?
The stability has increased exponentially since 2010. It is currently not an issue. There are fewer and fewer issues regarding how the backend handles data. The reliability factor is high.
What do I think about the scalability of the solution?
I have not encountered issues with scalability of the solution.
How is customer service and technical support?
I have had limited interraction with tech support. Whatever experience I had was OK. I have occasionally opened cases with them.
How was the initial setup?
It is straightforward, and not complex. If you have your IT director implement it, it has to be planned because users are using it and do not have a habit of cleaning up their mail boxes.
What's my experience with pricing, setup cost, and licensing?
Initially, we had issues with the licensing agreement, but we worked it out with Microsoft.
