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.

Cons

"I think it could be more scalable."
"I think that improvements should be made in creating greater abilities for Microsoft Exchange in terms of Research and Development."
"Microsoft Exchange could improve security. They can elevate a lot of security features."
"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 licensing model could be improved."
"There can be occasional challenges during the product's implementation phase, making it an area where improvements are needed."
"Microsoft Exchange could improve security. They can elevate a lot of security features."
"The solution should be easier to deploy."
"I would like to see a Microsoft schedule function added."
"There are security and performance issues which is one of the concerns of using an open-source product."
"It does have a few bugs. However, they are small and can be worked around."
"Some issues cause the solution not to function correctly or to cause downtime once a month."
"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."
"Zimbra must improve its solution to make it easy so that the users don't have to use webmail to connect to their accounts and log in to webmail every time. This is something that is lacking in Zimbra Collaboration. They should provide a better way to easily connect email applications on the desktop to the Zimbra server. They should also try to have more functionality for storage management, like Microsoft Exchange. Currently, the management of the email data must be done manually in Zimbra Collaboration, which we are finding very difficult. They should provide a way to save emails so that you can have more space on the server and storage. Because of the lack of this functionality, we are planning to migrate to Microsoft Exchange. Microsoft Exchange provides a better way to manage storage than Zimbra Collaboration. You cannot have a mail solution without storage management because emails will always increase. Zimbra Collaboration also needs tools for management. More back-office tools are required to manage the whole mailbox and space. You don't only manage emails but also the documents attached to the emails. Therefore, you require tools to select and decide what do you want to save or how do you want to free up space in your infrastructure."
"They should enhance its online meeting features."
"It does have a few bugs."
 

Pricing and Cost Advice

"The pricing is expensive."
"We can get Exchange in the cloud along with the Microsoft 365 license."
"Since my company is on Microsoft Cloud, we pay for the licenses per user. Compared to volume licensing, I would say the present licensing cost is not expensive."
"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."
"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."
"The solution's pricing is fine...I do think the tool offers value for money."
"The price of Microsoft Exchange could improve. In Egypt, the price keeps increasing."
"The solution is expensive to maintain because it requires frequent updates and ongoing server maintenance."
"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."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"Zimbra Collaboration offers a good price-to-feature ratio."
"The solution is competitively priced."
"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."
"We do not pay for licenses to use this solution."
"We pay yearly licenses for Zimbra Collaboration."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
