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

"The solution's hybrid deployment process could be improved, particularly for customers who initially started in the cloud and may want to return to an on-premises setup. Microsoft could make this transition more flexible."

"Microsoft Exchange could improve security. They can elevate a lot of security features."
"The pricing could be better, and it could have an easier implementation."
"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."

"Zimbra Collaboration's video conferencing could be improved."
 

Pricing and Cost Advice

"Its price is very affordable, and basically, it is the standard of the industry. We have the Exchange 365 subscription, which includes the usage of Exchange Online. I don't know the specific cost, but it is the retail price of Microsoft 365 E3 licenses. Microsoft's licensing is not very easy to understand. Microsoft changes rules every other day, which makes it difficult for us to understand the licensing not only for Exchange but also for other products. It can sometimes be really complex to understand what you need to have in order to comply with Microsoft licensing."
"Microsoft Exchange is an inexpensive application."
"The price of Microsoft Exchange could improve. In Egypt, the price keeps increasing."
"There is an annual cost to use Microsoft Exchange, and the price could be less expensive."
"Microsoft's licensing structure is too complex, but its prices are affordable, though not cheap."
"It is not expensive."
"The solution's pricing is fine...I do think the tool offers value for money."
"I rate Microsoft Exchange a four out of ten for pricing because it is quite cheap, and many companies use the solution."
"Zimbra Collaboration offers a good price-to-feature ratio."
"The solution is not expensive compared to other products."
"The solution is competitively priced."
"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."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"We do not pay for licenses to use this solution."
"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."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
