Efficient email management with seamless integration
We previously used Microsoft Exchange but have moved to an MDN email solution due to cost and user growth Microsoft Exchange is a user-friendly and easy-to-deploy solution, which is beneficial for handling emails even without professional support. It is effective in managing email integration…

One of the premium features was customized rooms tailored to the collaboration needs
Zimbra's strength lies in its individuality, and it should focus on leveraging its unique features rather than trying to emulate competitors. My organization has certified Zimbra technicians, so we believe we can utilize Zimbra certification. However, I was recently informed by Zimbra that no such certification exists. I have recently completed the test kit, and after the training, I will gain access to tickets. Therefore, if any clients are experiencing issues, we have a certified technical team available to provide support 24/7. This is how we can cater to our client's needs. I recommend Zimbra to small-scale and enterprise customers. Anyone, even those with 5 users, can opt for Zimbra. Overall, I rate the solution a nine out of ten.

"Because I have a lot of experience using Exchange, I would rate it between eight and nine out of ten."

"I find Exchange's basic mail features to be highly valuable."
"Microsoft Exchange is highly stable for the end-user systems."
"For an SMB, it is a recommendable email solution."
"Zimbra Collaboration's sharing features are most valuable."
"This is a good email solution and it's open-source which is great and the most important feature for us."

Cons

"The product or service could be improved in terms of Microsoft Outlook client compatibility."
"Nothing is perfect, that's why I am giving Microsoft Exchange a nine."
"For new users, it might take them some time to get used to the product."
"When an update wants to come, it should just come maybe once or twice rather than having us deal with constant updating."
"It is costly, so it depends on how much you want to pay."
"When we started using Exchange on the cloud, we had a lot of initial problems relating to our main database and we also experienced issues with the accidental deletion of inboxes, amongst other things."

"The support was lacking in my experience."
"Zimbra Collaboration does not have a solution roadmap as aggressive as the new collaboration mail solutions. Additionally, they can have a better interface and integration with single sign-on."
"The tool should improve its multi-cloud feature."
"The solution’s forums don't have much information or documentation on administration tasks."
"I would like to see a Microsoft schedule function added."
"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."
"The product must be more customizable."
"File sharing permissions with Nextcloud integration need improvement."
 

Pricing and Cost Advice

"Microsoft Exchange itself does not require a license, but users who will have mailboxes will require a license. It depends on the number of users to choose which license. If you exceed 2,000 mailboxes, it's preferable to get the enterprise license."
"Licensing costs for Microsoft Exchange have increased, but are still fair. For some users, the cost is high considering the number of functions and features they will use."
"Exchange is better for medium to large businesses because it can be quite costly for SMB, which may not need all the options the product provides."
"It would be nice if it used less resources to run on-premise."
"The platform has a reasonable price."
"It's working very well. There is no problem, but the price is not the best."

"The product is quite cheap."

"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"The price of the solution is low."
"The solution is not expensive compared to other products."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
"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."
"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."
