Founder and Managing Director at XOR BIT INFOTECH PRIVATE LIMITED
Allows collaboration and file sharing with a bigger inbox
Pros and Cons
- "Exchange Online doesn't just do email, it allows for collaboration with inbuilt chat and calling facilities and document sharing."
- "The demo version we were provided had issues with emails bouncing or being delayed."
What is our primary use case?
How has it helped my organization?
Exchange Online doesn't just do email, it allows for collaboration with inbuilt chat and calling facilities and document sharing. It also gives you a bigger inbox per account (50GB) than Gmail.
What needs improvement?
The demo version we were provided had issues with emails bouncing or being delayed. This hasn't happened since we purchased licenses, but it shouldn't happen even in the demo.
For how long have I used the solution?
I've been using this solution for eight years.

What do I think about the stability of the solution?
Exchange Online's stability is good once you have a license - in pre-licensing trial mode, it's not so good.
What do I think about the scalability of the solution?
The scalability is good.
How are customer service and support?
I wasn't happy with the support from the partner I was directed to and would prefer to get direct support from Microsoft. Microsoft's technical support is good.
How would you rate customer service and support?
Positive
How was the initial setup?
The initial setup is a little complex because you don't get any assistance - you just go to a site and do it yourself. I would rate it as two out of five.
What's my experience with pricing, setup cost, and licensing?
The licensing price is ok, I'd rate it as four out of five.
What other advice do I have?
I'd give Exchange Online a rating of nine out of ten.
Which deployment model are you using for this solution?
Public Cloud
Disclosure: My company does not have a business relationship with this vendor other than being a customer.

Completely scalable and flexible
Pros and Cons
- "The solution offers complete scalability and flexibility."
- "The solution should have more integration with other platforms."
What is our primary use case?
I use the latest version.
The solution obviates the need for infrastructure. The model is pay-per-use. We are not talking about a single email but a complete collaboration suite. One gets very well integrated IT which is tightly stitched with collaborations. One can chat and field calls. As such, it is not only Exchange Online coming on, but Office 365 Suites, which Microsoft provides the users. This availability ranges from first-line workers to CEO level users, depending on one's requirements. All the industry needs are covered. One can take the model best suited to him and tailor his solution to his investment capacity needs.
This means that the solution offers complete scalability and flexibility. A business user who occupies a very small portion of the industry can pay less for a suite. The desktop and web versions are also options. The solution's handy. One can use it on his mobile, or any other devices, including multiple devices and single identity. So, the picture is comprised of many components.
What needs improvement?
The solution should have more integration with other platforms. It is more integrated to the collaboration suite and other document management systems.
For how long have I used the solution?
I have been using Microsoft Exchange Online for the last couple of years.
What do I think about the scalability of the solution?
The solution boasts complete scalability.
How was the initial setup?
As the solution is cloud-based, there is no installation required. There is no need to worry about its applications and no license. We are talking about per-user subscription-based use.
When it comes to the license, we are already talking about Microsoft. There is also provisioning. Otherwise, it's just plug and play. There are not many administrative tasks involved.
What's my experience with pricing, setup cost, and licensing?
The model is one which is pay-per-use go. There is no license. We are talking about per-user subscription-based use.
When it comes to the license, we are already talking about Microsoft. There is also provisioning. Otherwise, it's just plug and play. There are not many administrative tasks involved.
A business user who occupies a very small portion of the industry can pay less for a suite. The desktop and web versions are also posibilities.
What other advice do I have?
The solution is an SaaS cloud-based solution.
There are a thousand-plus users making use of the solution in our organization.
I would recommend the solution to others, although this depends on the capacity one is interested in and whether he utilizes another solution. For someone who wants the complete bouquet of the solution, he can go with Office 365. There are others solutions which are geared to one who is only interested in email capabilities. There are many cloud-based solutions available, although these vary with the needs of the organization. Office 365 is geared towards someone who is looking for a complete collaboration suite. Someone who is not looking for this is advised to go with another solution.
I rate Microsoft Office Exchange as an eight to nine out of ten.

Massive storage capacity with 100 GB per user mailbox
Pros and Cons
- "The online version is faster, as it is a cloud instance. We can have massive mailbox capacity: 100 GB per user, which is huge. We can't provision such capacity internally, as the company would get burnt out paying for mailbox storage."
- "I would prefer an anti-malware functionality in at least the basic version."
How has it helped my organization?
In terms of mail, it is on the cloud and there is a lot of dependency on the internal server, which is not exactly great.
The online version is faster, as it is a cloud instance. We can have massive mailbox capacity: 100 GB per user, which is huge. We can't provision such capacity internally, as the company would get burnt out paying for mailbox storage. You have no idea how relieved the Fortune 500 company mail admins were with this.
What is most valuable?
The onboard anti-spam is pretty good. Therefore, you do not need to invest in an additional anti-spam product. If needed, invest in an anti-malware solution, specifically for weeding out damage at the email level.
It has massive storage capacity with 100 GB per user mailbox.
What needs improvement?
I would prefer an anti-malware functionality in at least the basic version.
For how long have I used the solution?
I have deployed Office 365 and migrated my on-premise version to the cloud. Though I was a bit skeptical to move when money and backup functionality came into picture, the migration started to gain momentum. It has been more than four years since we started to use it.
What do I think about the stability of the solution?
There is no server downtime. It never runs out of mechanical resources as it is the cloud version.
