Harry Murdani - PeerSpot reviewer
Helps with email services and communication with internal and external contacts
Everything is useful. The only useful thing Microsoft Exchange could do is give us more of a discount on pricing because it's so expensive. Regarding the calendaring functions of Exchange, there is a problem when scheduling an event for the whole day. When you click the whole day event, the scheduling doesn't really work. For example, if I schedule a meeting with you and block your whole day, instead of just putting a time from morning to afternoon, other people can still block your time, which results in double booking. It's kind of a bug that allows people to double-book. So, the scheduling isn't working properly yet. We also faced challenges with backup services. You need to use a third-party backup solution to back up the whole Exchange server properly. You can't use the native Windows backup services. It's like they're forcing me to buy another product, which means additional costs. The backup solution and the double booking issues. If Microsoft Exchange can fix these two things, then it will be very good.

Deploys quickly and has a good web interface
Zimbra Collaboration has a good web interface When it comes to administration tasks like configuring specific filters or group signatures, I have to dig into the configuration since there's nothing in the graphical or web interface. The solution’s forums don't have much information or…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It's user-friendly."
"Exchange is a robust system that is well suited for an enterprise environment. It's always up, and we hardly face any technical issues. Exchange has a web interface and integrates perfectly with Microsoft Outlook. This web interface can be easily used to change the passwords from the domain controllers."
"Communication is the most valuable feature of the solution."
"It integrates well with calendar, scheduling, etc. It's easy for employees to make meetings and plan their agendas."
"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."
"We've been using Exchange as an email platform. Our clients require multi-country, multi-regional email collaboration with controlled mail flow. The most valuable feature is the capability of message tracking and the protection of user data."
"It's very well integrated with OneDrive and Teams Calendar."
"I find Exchange's basic mail features to be highly valuable."
"The Zimbra Collaboration's most valuable feature is web access."
"The configuration is simple."
"One of the premium features was customized rooms tailored to the collaboration needs. Many of the clients customize features such as organization logos and scanners."
"The solution is easy to implement."
"The most valuable feature of Zimbra for our team's productivity is its efficiency in handling email communication."
"Zimbra Collaboration's best feature is its compatibility with Microsoft's ActiveSync protocol, which allows users to use Outlook on Windows or MacOS."
"One of the most valuable features involves the solution's automatic backup, which I find to be pretty simple and straightforward, and obviates the need for additional software."
"Network NG Modules are valuable to us."
 

Cons

"It doesn't work very well on a virtual machine. We had to move it around. There are also issues when you try to move it between computers."
"There is a lot of spam email that comes in, so they should add functionality to help fix this problem."
"The biggest issue with Microsoft Exchange is its high cost, especially in pricing for license upgrades and expansion to more users."
"The main problem with Microsoft products is that we're constantly required to install patches and fixes."
"I don't have the best impression of customer service and support. It should be faster and more clear, and more human. T"
"Some users encounter stability issues. I connect with the support team through my local partner, which takes time."
"The setup is difficult so could be easier."
"In terms of what should be improved, they should probably move to a cloud option like Office 365. We would like to get this functionality without the need to deploy complex hardware and software solutions. This should be the next thing, making Exchange more related to Office products, which are more cloud-oriented, less on-premise or desktop-oriented solutions, like the direction Google is strongly moving towards."
"The tool should improve its multi-cloud feature."
"I can confidently say that Zimbra is good enough for 2,000 client users. But, at the same time, if my client needs more than that and we have two options—Zimbra or Microsoft—I'm going with Microsoft because many admins will speak to Microsoft's ability to handle that many."
"They should enhance its online meeting features."
"It is good and competent, but you have to pay for video and group chat features."
"The support was lacking in my experience. However, recently the support I received was good. Perhaps they have improved."
"I would like to see a Microsoft schedule function added."
"It does have a few bugs."
"File sharing permissions with Nextcloud integration need improvement."
 

Pricing and Cost Advice

"Microsoft Exchange is an inexpensive application."
"Compared to the other options in the market, the licensing costs attached to Microsoft Exchange seem reasonable."
"The price of Microsoft Exchange is reasonable."
"I have Outlook 365 Professional, and Exchange comes in the bundle with other solutions, such as Word and OneDrive. I pay for the use of the bundle monthly and I can imagine if you are a company with many licenses the pricing model would be a lot different."
"The product pricing is reasonable if you utilize its full suite of features."
"Its price is okay."
"The platform has a reasonable price."
"It's working very well. There is no problem, but the price is not the best."
"The solution is not expensive compared to other products."
"The solution is competitively priced."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"When it comes to the licensing of Zimbra Collaboration, my license covers the servers and I find its terms to be much simpler than those of Microsoft Exchange."
"We do not pay for licenses to use this solution."
"We pay yearly licenses for Zimbra Collaboration."
"Zimbra Collaboration offers a good price-to-feature ratio."
"It's very expensive. When we compare the cost with Google Workspace, it's so expensive."
