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.

Quotes from Members

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

Pros

"The tool's most valuable feature is associated with the fact that it stands out for being beneficial for managing emails."
"What I love about Microsoft Exchange is the good integration since 2013, particularly its integration with the calendar and other software such as Zoom, TeamViewer, AnyDesk, etc."
"The most valuable feature of Microsoft Exchange is its communication capabilities."
"Microsoft has a very good support team."
"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."
"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 an excellent product from Microsoft. It provides more flexibility to the end-users. As it's connected with Teams, it also enables collaboration."
"Support is very good."
"The solution is easy to implement."
"Zimbra Collaboration has a good web interface."
"Good email solution and it's open-source."
"Network NG Modules are valuable to us."
"The most valuable feature is sending messages as well as text and documents. It's a big solution for us since internal communication is a must in our organization."
"Zimbra Collaboration's best feature is its compatibility with Microsoft's ActiveSync protocol, which allows users to use Outlook on Windows or MacOS."
"The Zimbra Collaboration's most valuable feature is web access."
"The most valuable feature of Zimbra Collaboration is email functionality."
 

Cons

"When an update wants to come, it should just come maybe once or twice rather than having us deal with constant updating."
"There is a lot of spam email that comes in, so they should add functionality to help fix this problem."
"They could offer simultaneous features for Exchange Online and on-premises versions. Specific features such as litigation hold and audit setups should be available on-premises."
"At the end of the day, the biggest area for improvement is having better and more knowledgeable support technicians."
"I'd like the archiving process to be faster."
"The product or service could be improved in terms of Microsoft Outlook client compatibility."
"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."
"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 are some security issues."
"It is good and competent, but you have to pay for video and group chat features."
"The solution’s forums don't have much information or documentation on administration tasks."
"Some issues cause the solution not to function correctly or to cause downtime once a month."
"The installation is not straightforward, it can take two days for the full implementation."
"File sharing permissions with Nextcloud integration need improvement."
"We have had an issue with security."
"I would like to see a Microsoft schedule function added."
 

Pricing and Cost Advice

"Its price is fair."
"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. The larger the number of users, the lesser the price. For small to medium companies like us, we feel it is expensive."
"It's a little bit expensive."
"We renew the product license with Microsoft every three years. The cost is included within a bundle of services. It's an enterprise agreement with Microsoft."
"I don't have enough information about the licensing costs of Microsoft Exchange, but I do know that you need two types of licenses to run it. You need the product key and the client access key to activate Microsoft Exchange. This means that apart from the standard Microsoft Exchange licensing fees, you have to pay additional costs."
"It's working very well. There is no problem, but the price is not the best."
"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."
"It would be nice if it used less resources to run on-premise."
"The solution is competitively priced."
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"The solution is not expensive compared to other products."
"We pay yearly licenses for Zimbra Collaboration."
"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."
"It's very expensive. When we compare the cost with Google Workspace, it's so expensive."
"Zimbra Collaboration is less expensive than Microsoft Exchange. Zimbra works for small companies because it is not expensive. Zimbra Collaboration has more security tools than Microsoft Exchange. If you are choosing between Zimbra Collaboration and Microsoft Exchange, you have to take into account the cost of security tools with Microsoft Exchange. When you purchase Microsoft Exchange, you will also have to purchase tools for security, which adds to the cost. The migration from Zimbra Collaboration to another email solution is very simple and easy. Migration from Microsoft Exchange to another email solution is very difficult. Microsoft doesn't allow migration that easily. In fact, you have to pay for tools to do that. You have to buy some expensive tools to migrate."
