Protects data privacy
Pros and Cons
- "On-premises Microsoft Exchange is good because it protects data privacy."
- "Microsoft could improve on Exchange's hybrid deployment or HCW. They need to improve on that because I was having many issues with HCW in our environment at times."
What is our primary use case?
What is most valuable?
On-premises Microsoft Exchange is good because it protects data privacy. It depends on the client because clients want to share their mailing communication with anyone, like vendors and all. So it's purchasing like on-premises server exchange email. So if they are okay with storing data to Online Exchange and all Office 365, they're buying that one. So it depends on the client's needs entirely.
What needs improvement?
Microsoft could improve on Exchange's hybrid deployment or HCW. They need to improve on that because I was having many issues with HCW in our environment at times. And there are certain things I'm not clear about, like eDiscovery on our on-premises level. There were some features that I liked, such as Unified Messaging and Advance Search, but Microsoft removed them in 2019.
For how long have I used the solution?
I've been working with Microsoft Exchange off and on for several years. It's not something I use daily. I work with it when I'm brought in to provide migration or implementation services.

What do I think about the stability of the solution?
Microsoft Exchange's stability all depends on the environment. So when we are configuring and implementing, we're optimizing everything for performance. I've been working for 10 years in that field, so if anyone changes a configuration, we take into consideration the impact it will have on the stability.
What do I think about the scalability of the solution?
Microsoft Exchange is scalable, but it depends on the company and how much they're willing to pay. Scalability is only limited by the price.
How are customer service and support?
When I'm migrating or implementing, and I have an issue, I check out a few things, like which applications are running. I also check the network security to discover all the basic stuff like server performance. Then, I suggest how many people are required to address these technical issues and at what level. I escalated to Microsoft two or three times. That was what the client needed, so we contacted Microsoft and got an LSA for that.
How was the initial setup?
Installing and configuring Microsoft Exchange is a little bit complex. Initial installation takes around 45 minutes to 30 minutes. Then we have to do some configuration. The basic configuration takes one to two days, depending on the environment. When we are implementing in a hybrid environment, we need to make some manual adjustments. For example, there was an issue with creating multiple databases during one implementation, like active and passive copy. That was not transferring and working in that scenario.
Often we're working with a company that has already deployed. That's where we need to understand our workflow and main flow. For example, say there is a company that already deployed version 10, and we need to upgrade to 16 or 19. So we would have to understand their needs, like if there is a hybrid configuration or some other existing requirement.
What's my experience with pricing, setup cost, and licensing?
There are different pricing tiers, and I don't remember all the costs for that. For Office 365, it depends on the license price per mailbox user. And for the on-premises version, there is a scale license. Overall, it's about average for the market. The on-premises license is a bit more costly because there is a requirement for OS-level licensing. And we offer a standard edition, so it is a little more straightforward to figure out the cost. We can also go for enterprise pricing. It depends on what the client needs.
What other advice do I have?
I rate Microsoft Exchange eight out of 10.
Which deployment model are you using for this solution?

Integrates well, easy to use, but stability needs improvement
Pros and Cons
- "Microsoft Exchange is a powerful solution. It can easily integrate with Active Directory and other business applications. It does not require any training, it is flexible and simple to use. When comparing Microsoft Exchange to other solutions, such as Lotus Note, it is more straightforward for business."
- "From a reliability perspective, they need to improve the search engine, it is not very powerful."
What is our primary use case?
We use Microsoft Exchange on a daily basis for our business. However, we are moving to Office 365, which means that this will be available on the cloud. This is also a part of the Microsoft enterprise agreement. We receive a lot of other support applications along with Exchange. For example, Teams is included and integrates seamlessly, and we can do many functions, such as schedule meetings.
How has it helped my organization?
We use Microsoft Exchange on a daily basis and it helping our business, we are able to integrate easily with many of our business applications.
What is most valuable?
Microsoft Exchange is a powerful solution. It can easily integrate with Active Directory and other business applications. It does not require any training, it is flexible and simple to use. When comparing Microsoft Exchange to other solutions, such as Lotus Note, it is more straightforward for business.
What needs improvement?
From a reliability perspective, they need to improve the search engine, it is not very powerful.
The security is not the best, it is not able to filter some of the spam and malware emails that pass through no matter what security protocols that we have set. Recently we had two incidents where we had to stop the business for one day. I am not sure if it is a problem with our implementation, or is it a problem with something else.
For how long have I used the solution?
I have been using Microsoft Exchange for approximately four years.
What do I think about the stability of the solution?
There are some difficulties with the Microsoft Exchange application. For example, it sometimes gets frozen and we have not determined the cause. When frozen we need to close it, and then again open it again. It takes a while to reload the application if the volume is high and when I have many emails. They need to improve on stability.
Many solutions have bugs and glitches and I do not think Microsoft can help it, it is a huge package and there are updates frequently. However, if one was to implement all the standard policies the bugs would be fewer. If I do not implement a certain standard Microsoft Exchange policy, then it should stop me. It should not allow me to do certain operations that would put me at risk. There should be fewer manual controls to prevent improper configuration.
What do I think about the scalability of the solution?
The solution is scalable. We have approximately 300 users using the solution and there are some companies that have 10,000 users.
How are customer service and technical support?
The support for Microsoft is very good.
How was the initial setup?
The installation process was straightforward. There were not that many difficulties.
What's my experience with pricing, setup cost, and licensing?
We are currently using enterprise licenses for the solution. They are different pricing models available. There are individual, cloud-based, and enterprise licenses all with different pricing models. Typically, the larger the number of users, the lesser the price. For small to medium companies like us, we feel it is expensive. However, for a large company, where they have thousands of employees the cost is distributed. We do not receive this kind of benefit because of the small company size. They should provide more discounts for the small companies because we do not complain or create too many problems for Microsoft.
For large companies that have 10,000 employees, the problems are huge and different. They use a lot of Microsoft support. Small companies that have less than 300 people should get a discount, we do not qualify for their volume discount that starts at 500 people. They should not put these kinds of restrictions on giving discounts. I expect Microsoft to come up with some different options for small to mid companies in the future.
Which other solutions did I evaluate?
We have evaluated Microsoft Office 365.
What other advice do I have?
Overall when taking into account implementation, user experience, the flexibility of the solution it has always been very good. There are more benefits than drawbacks.
I rate Microsoft Exchange a seven out of ten.
Which deployment model are you using for this solution?
On-premises

Easy to set up and good for retrieving data but updates happen too frequently
Pros and Cons
- "The initial setup is easy."
- "When an update wants to come, it should just come maybe once or twice rather than having us deal with constant updating."
What is our primary use case?
I just use it to retrieve my data. I'm just mostly leveraging it to retrieve some archive data, so I haven't really used it on a more advanced level.
For example, I was changing my email, so I wanted to retrieve some data I had from the previous address. That was the only time I used Microsoft Exchange to retrieve my archive information. Aside from that, I don't think I've used it for any other use cases.
What is most valuable?
I haven't really used it for something advanced. Most of my use cases are just to retrieve my information. Microsoft Exchange is just a part of your Office package, so you just have it inbuilt. I really haven't used it much.
The initial setup is easy.
What needs improvement?
I've not really gone through the application. The only time I use it is when I want to retrieve particular emails that I had.
I really have issues with updates. When an update wants to come, it should just come maybe once or twice rather than having us deal with constant updating. If I have a company constantly updating me on additional features and everything, I get to the point that I just don't read the emails or classify them as junk. However, if I get an update maybe twice, I pay more attention. They need less frequent updates and reminders.
For how long have I used the solution?
I've been using the solution for a year now.
What do I think about the stability of the solution?
I can't speak to the stability as I haven't used it too much.
What do I think about the scalability of the solution?
I haven't tested the scalability. Most of my applications that I just use for my own work.
While it's used in the company, I just use it for my own personal purposes, such as retrieving email.
How are customer service and support?
I've never reached out to support.
When I was using Exchange, I didn't know how to initially use it when I wanted to use it to get to my data. To find out, I checked YouTube, and I got an idea of how to use it. It wasn't a problem for me.
Which solution did I use previously and why did I switch?
I have not used any other similar solution previously.
How was the initial setup?
It's straightforward to set up. If you have your Office package, everything is straightforward.
What about the implementation team?
I did not need the assistance of a consultant or integrator during setup.
What's my experience with pricing, setup cost, and licensing?
This is a company product. I'm not in charge of licensing. I'm not sure what it would cost.
What other advice do I have?
I'm not sure if I could recommend the solution as I haven't taken a deep dive into its functionality. I haven't done any advanced work with it. I've only ever retrieved my own data.
I'd rate it five out of ten. I was able to achieve what I needed to, however, I haven't used it much.
Which deployment model are you using for this solution?

It's easy to use and the built-in calendar is helpful
Pros and Cons
- "Exchange is easy to use. It also has a built-in calendar for all the stuff I'm supposed to be looking at and doing. Exchange tells you if you have a doctor's appointment or a scheduled call. It also has a place to store and manage your contacts. If I want to add a new contact, it will put in information about that contact stored anywhere within the Microsoft Suite."
- "They keep making all these changes, and our system was down for four or five days. They finally got it up, but there are still lots of quirks."
How has it helped my organization?
Email is something we constantly use.

What needs improvement?
They keep making all these changes, and our system was down for four or five days. They finally got it up, but there are still lots of quirks.
What do I think about the stability of the solution?
Exchange is about 90 percent stable, but they're working on it. In the next two or three weeks, they should be able to do it. I know what they're going through.
How are customer service and support?
Microsoft has teams in different countries, so they will help you depending on your problem. If you have an issue with something else, they will email you a link that puts you into contact with the team you should talk to. I gave them a lot of issues, and they're working on them. They're saying they will do everything they can to make it work.
The only issue is that the phone connection is sometimes bad because it's a foreign country. It's something you have to live with. You can repeat what they said and ask if you heard them correctly, but they're accommodating.
What other advice do I have?
I rate Microsoft Exchange nine out of 10. My advice for prospective Exchange users is to have an experienced person deploy it and show you how it's done. They should give instructions on how to make it into a server. That's critical. If you set up a server and think that's the end of it, you could go down the wrong alley.
You'll want some help initially, but on the other hand, you definitely want to learn to use the solution yourself. I recommend getting a support contract with someone who knows the solution. There is so much specialization in this world. For example, a veterinarian and a cardiologist are both doctors, but would you see your vet about a heart problem?

Highly stable and scalable
Pros and Cons
- "Microsoft Exchange is highly stable for the end-user systems. When we move to Office 365, it will be even more stable even. There's less administration required and it's very robust. We are really quite happy in using that."
- "Microsoft Exchange could improve by being more secure. We are always looking to have more security."
What is our primary use case?
We are using Microsoft Exchange for collaboration but mainly for email.
What needs improvement?
Microsoft Exchange could improve by being more secure. We are always looking to have more security.
For how long have I used the solution?
I have been using Microsoft Exchange for approximately 20 years.
What do I think about the stability of the solution?
Microsoft Exchange is highly stable for the end-user systems. When we move to Office 365, it will be even more stable even. There's less administration required and it's very robust. We are really quite happy in using that.
What do I think about the scalability of the solution?
The stability can depend on the user's internet speed. If the speed is good then the solution can be scalable.
We have approximately 3,000 to 4,000 users using this solution.
What about the implementation team?
There are two to three people doing the maintenance of the Microsoft Exchange.
What's my experience with pricing, setup cost, and licensing?
We have had an enterprise license agreement for three years. We are always seeking more value for our money, the price could be reduced.

We're confident in the solution because the support is always there for us
Pros and Cons
- "Exchange's interface is good. All of our engineers like it and are accustomed to using it."
- "The main problem with Microsoft products is that we're constantly required to install patches and fixes."
What is most valuable?
Exchange's interface is good. All of our engineers like it and are accustomed to using it.
What needs improvement?
The main problem with Microsoft products is that we're constantly required to install patches and fixes. In fact, Microsoft frequently publishes, which is in itself a guarantee of quality, security updates especially for the OS that we are forced to apply. The problem is, this causes us to do a lot of testing before we go into production to make sure that our systems continue to function properly.
For how long have I used the solution?
I've worked as an administrator of Microsoft Exchange for five years.
What do I think about the stability of the solution?
We haven't identified any serious problems with Exchange.
How are customer service and support?
We have always used Exchange. That's a strategic choice for our company. We are confident in Microsoft because their support is always there for us.
How was the initial setup?
The setup was easy. When we first deployed Exchange, we had some guidance from Microsoft, but now our engineers use it effortlessly.
What other advice do I have?
I rate Microsoft Exchange eight out of 10. I hope Microsoft will continue to support the on-premises versions of their products because they are increasingly orienting themselves toward Exchange in the cloud. Unfortunately, cloud services are unavailable here in Nigeria.
