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.

"It is a very scalable solution."
"It integrates well with calendar, scheduling, etc. It's easy for employees to make meetings and plan their agendas."

"Zimbra Collaboration is a good tool for video calls...Zimbra Collaboration's initial setup phase was easy."
"The most valuable feature of Zimbra for our team's productivity is its efficiency in handling email communication."
"Zimbra Collaboration is light to manage. It works on the Linux operating system, which is far better to manage than Microsoft Windows. Microsoft Exchange works only on the Windows server. We prefer working on the Linux server for security reasons and ease of management. Zimbra Collaboration also has some integrated tools for security. It some modules to fight malware. These modules are not very powerful but are still doing a great job. Microsoft Exchange doesn't have a basic module. You have to purchase a security solution and add it to the solution. The cost of Zimbra Collaboration is one more reason for liking it. It is also very simple to migrate from Zimbra Collaboration to another email solution."

Cons

"Microsoft Exchange is highly stable. However, after receiving some updates it can be unstable."

"It's not always the finest solution in terms of integration with products that are not from Microsoft. It integrates very well with Microsoft products but not with third-party products."
"The only thing that could be improved is the pricing."
"The tool is not easy to use. Every person has to have at least administration-level experience to use the tool."
"The support needs to be more knowledgeable."
"Currently, its administration is too cumbersome. It's unwieldy. It's slow. It consumes too many resources. Configuration needs to be much more streamlined and administratively automated."
"The new patches are, at times, not so good, so we don't install them, causing the tool to be not so stable overall."
"Zimbra Collaboration's video conferencing could be improved."
"The solution could improve by making it easier to use."
"There are some security issues."
"It is good and competent, but you have to pay for video and group chat features."

"The solution could use more integration with third-party tools."
 

Pricing and Cost Advice
