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 easy to use; it also has a built-in calendar for all the stuff I'm supposed to be looking at and doing, tells you if you have a doctor's appointment or a scheduled call, and has a place to store and manage your contacts, automatically filling in information about a new contact stored anywhere within the Microsoft Suite."
"It is very well integrated with other Microsoft programs, teams, and so on; they work well together."
"The most beneficial aspects of Microsoft Exchange are that it is solid, dependable, and reliable."
"Support is very good."
"Overall, I am satisfied with the product."
"Microsoft Exchange's most valuable feature is that it's old-fashioned communication, meaning it's good for people who aren't able to work comfortably in a cloud environment."
"It ensures high availability and resilience, allowing seamless recovery from potential failures and making it a reliable option for business-critical operations."
"The most valuable feature of Microsoft Exchange is its ease of use."
"For an SMB, it is a recommendable email solution."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
"I think Zimbra is more reliable and competitive than Microsoft because they offer an open-source version."
"The web interface is powerful and easy to use."
"Most valuable to us is the fact that it's open source, so it's possible to do a lot of customization."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"Zimbra Collaboration is mainly used for messaging, emails, calendars, video conferencing, and document sharing."
"The Zimbra Collaboration's most valuable feature is web access."
 

Cons

"The licensing model could be improved."
"Some users encounter stability issues. I connect with the support team through my local partner, which takes time."
"From a reliability perspective, they need to improve the search engine, it is not very powerful."
"I think that improvements should be made in creating greater abilities for Microsoft Exchange in terms of Reasearch and Development."
"There is a problem when scheduling an event for the whole day."
"Microsoft Exchange could improve the price."
"When an update wants to come, it should just come maybe once or twice rather than having us deal with constant updating."
"The security features could be improved. There should be a better policy management system."
"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."
"The support was lacking in my experience."
"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."
"Zimbra Collaboration's video conferencing could be improved."
"It does have a few bugs."
"File sharing permissions with Nextcloud integration need improvement."
"Because of the lack of this functionality, we are planning to migrate to Microsoft Exchange."
"Zimbra is not very stable, but it's okay."
 

Pricing and Cost Advice

"The product is quite cheap."
"I rate Microsoft Exchange's pricing a six out of ten."
"Compared to the other options in the market, the licensing costs attached to Microsoft Exchange seem reasonable."
"I rate Microsoft Exchange a four out of ten for pricing because it is quite cheap, and many companies use the solution."
"They are flexible when it comes to pricing, unlike most of the other vendors I have dealt with."
"We renew the product license with Microsoft every three years. The cost is included within a bundle of services. It's an enterprise agreement with Microsoft."
"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."
"Microsoft's licensing structure is too complex, but its prices are affordable, though not cheap."
"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."
"The solution is competitively priced."
"The price of the solution is low."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"We do not pay for licenses to use this solution."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"The solution is not expensive compared to other products."
