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.

Quotes from Members

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

Pros

"Because I have a lot of experience using Exchange, I would rate it between eight and nine out of ten."
"Customers can benefit from this new pricing model because it's expensive, and now with the subscription, they can budget for this."
"We have always used Exchange, that's a strategic choice for our company, and we are confident in Microsoft because their support is always there for us."
"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."
"Communication is the most valuable feature of the solution."
"The email management system is very easy to set up, configure, and use."
"I find Exchange's basic mail features to be highly valuable."
"It's so much of a part of what I do every day that I don't give it a lot of thought. It just works, for the most part, until it doesn't, in which case I call tech support."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
"The most valuable feature of Zimbra Collaboration is the cost."
"The backup and storage management features of Zimbra Collaboration are valuable."
"We can control all the data in my IT infrastructure."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"The logs, troubleshooting, and tracking we have found to be the most valuable features, and when we have any issues with lost messages these features are useful because it is very easy to track and log."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"Zimbra Collaboration's best feature is its compatibility with Microsoft's ActiveSync protocol, which allows users to use Outlook on Windows or MacOS."
 

Cons

"Load balancing is lacking."
"Microsoft Exchange is highly stable. However, after receiving some updates it can be unstable."
"Deployment should become a bit easier, the process is a bit complicated. There are a lot of complications compared to Gmail For Business, which is a bit easier when it comes to configuration."
"Exchange's management could be improved a bit, and its troubleshooting tools are limited at times."
"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."
"The biggest issue with Microsoft Exchange is its high cost, especially in pricing for license upgrades and expansion to more users."
"In terms of what should be improved, they should probably move to a cloud option like Office 365. We would like to get this functionality without the need to deploy complex hardware and software solutions. This should be the next thing, making Exchange more related to Office products, which are more cloud-oriented, less on-premise or desktop-oriented solutions, like the direction Google is strongly moving towards."
"The pricing could be better, and it could have an easier implementation."
"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."
"There are some bugs we found that could be fixed."
"I would like to see a Microsoft schedule function added."
"The support was lacking in my experience."
"Zimbra should provide a desktop client. Right now, we are using a web browser for accessing our emails. There should also be a desktop client."
"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."
"It would be great if a group chat feature were created to allow for a team environment."
"We had a couple of issues with stability, but nothing that I couldn't work around or fix myself. Zimbra is a powerful product, but since VMware bought it, changes and bug fixes have been very slow in coming."
 

Pricing and Cost Advice

"I rate Microsoft Exchange a four out of ten for pricing because it is quite cheap, and many companies use the solution."
"The price of Microsoft Exchange could improve. In Egypt, the price keeps increasing."

"Its price is okay."
"There is an annual cost to use Microsoft Exchange, and the price could be less expensive."
"Microsoft Exchange is an inexpensive application."

"It's a little bit expensive."
"Zimbra Collaboration is expensive, and there is no perpetual license option."

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."
