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

"Exchange is very scalable, it's one of the most important things about this software."
"Exchange's best feature is single sign-on access using the Microsoft Identity framework."
"Microsoft Exchange is comparable to the Outlook client. Both are Microsoft products, and most people are familiar with Outlook. This is why the best feature of Microsoft Exchange is the ease of use. It is more compatible with the client software, especially for Microsoft Outlook. There are a lot of features available that are required for businesses users."
"The most valuable feature of Microsoft Exchange is its ease of use."
"It is enterprise-friendly, and many organizations use it."
"What I love about Microsoft Exchange is the good integration since 2013, particularly its integration with the calendar and other software such as Zoom, TeamViewer, AnyDesk, etc."
"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."
"Microsoft support is very good."
"Zimbra Collaboration has a good web interface."
"The pricing of the solution is excellent; it's a newer solution with a modern interface and dashboard, the interface itself is very responsive and easy to navigate, the initial setup is very simple and straightforward, the stability is good and keeps getting better with each new update, and the solution really does scale very easily."
"Premium features, such as auto discovery and archiving, mobile management and HSM, make life much easier."
"Zimbra Collaboration's sharing features are most valuable."
"The most valuable feature of Zimbra for our team's productivity is its efficiency in handling email communication."
"I think Zimbra is more reliable and competitive than Microsoft because they offer an open-source version."
"The logs, troubleshooting, and tracking we have found to be the most valuable features. We have any issues with lost messages the features are useful. It is very easy to track and log."
"We can control all the data in my IT infrastructure."
 

Cons

"They keep making all these changes, and our system was down for four or five days."
"There are issues when you add your domain to Microsoft Tenant, and you try to create that. Which is a problem for me."
"One major area for improvement is the need for repeated authentication when running a meeting."
"They keep making all these changes, and our system was down for four or five days. They finally got it up, but there are still lots of quirks."
"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."
"The issue with Exchange has always been storage."
"Microsoft could improve on Exchange's hybrid deployment or HCW. They need to improve on that because I was having many issues with HCW in our environment at times."
"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."
"The tool should improve its multi-cloud feature."
"There are security and performance issues which is one of the concerns of using an open-source product."
"There can be difficulties resolving problems on the server side when problems arise."
"It would be great if a group chat feature were created to allow for a team environment."
"In the next release, Zimbra Collaboration should include a security feature to allow access for mobile device administrators."
"It does have a few bugs."
"The solution’s forums don't have much information or documentation on administration tasks."
"The installation is not straightforward, it can take two days for the full implementation."
 

Pricing and Cost Advice

"Its price is fair."
"The product pricing is reasonable if you utilize its full suite of features."
"I don't have enough information about the licensing costs of Microsoft Exchange, but I do know that you need two types of licenses to run it. You need the product key and the client access key to activate Microsoft Exchange. This means that apart from the standard Microsoft Exchange licensing fees, you have to pay additional costs."
"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 product is quite cheap."
"Compared to the other options in the market, the licensing costs attached to Microsoft Exchange seem reasonable."
"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."
"There are different prices depending on the customer's use cases and amount of users. The price of the solution could improve."
"We do not pay for licenses to use this solution."
"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 expensive, and there is no perpetual license option."
"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."
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
"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"
