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.

Pros

"If you don't really mind the cost then go for Microsoft."
"Overall, I am satisfied with the product."
"The initial setup is easy."
"It is easy to use and we can allow many users because now our users are scattered, they cover a wide area, and we can use it from anywhere, which is the main benefit for us."
"This is a good product but our version is reaching end-of-life."
"Microsoft Exchange has good performance and is user-friendly."
"It ensures high availability and resilience, allowing seamless recovery from potential failures and making it a reliable option for business-critical operations."
"The technical support services are good."
"Zimbra Collaboration is mainly used for messaging, emails, calendars, video conferencing, and document sharing."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"Premium features, such as auto discovery and archiving, mobile management and HSM, make life much easier."
"The backup and storage management features of Zimbra Collaboration are valuable."
"A lot of other products like Microsoft Exchange offer email or collaboration features, but they are not as fast as Zimbra."
"I think Zimbra is more reliable and competitive than Microsoft because they offer an open-source version."
"Zimbra Collaboration's best feature is its compatibility with Microsoft's ActiveSync protocol, which allows users to use Outlook on Windows or MacOS."

Cons

"Microsoft Exchange needs to improve how it handles and assigns policy and security."
"I think that improvements should be made in creating greater abilities for Microsoft Exchange in terms of Reasearch and Development."

"The solution is stable, but it could improve. It's crashing if there is a big mail database. The Zimbra solution is better in this area."
