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."
"Exchange's best feature is single sign-on access using the Microsoft Identity framework."
"I like the logistics and Microsoft protocol of reaching Outlook anywhere; it's a user-friendly product."
"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."

Cons

"In terms of configuring the product, that's definitely an area in which they can make some improvements on."
"The default storage capacity is too small."
"From a security perspective, Microsft Exchange can be improved. All that needs to be added is security, but that's an internal hierarchical problem from the product itself and not the end-users."
"It's not always the finest solution in terms of integration with products that are not from Microsoft. It integrates very well with Microsoft products but not with third-party products."
"The calendar integration in Exchange is not that great. The email features are okay, but it doesn't integrate well with the calendar and appointments, especially Zoom appointments. It integrates fine with Microsoft Teams, but Zoom is a challenge."
"When an update wants to come, it should just come maybe once or twice rather than having us deal with constant updating."
"Its stability is not so great. We can't move mailboxes because of a corrupt file or random issues, which causes headaches."
"The security features could be improved. There should be a better policy management system."

Pricing and Cost Advice

"There are different prices depending on the customer's use cases and amount of users. The price of the solution could improve."
"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."
"Microsoft's licensing structure is too complex, but its prices are affordable, though not cheap."
"The product pricing is reasonable if you utilize its full suite of features."
"I rate Microsoft Exchange's pricing a six out of ten."
"Licensing fees are paid monthly."
"The pricing is expensive."
"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."
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"We pay yearly licenses for Zimbra Collaboration."
"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."
"The solution is not expensive compared to other products."
"The price of the solution is low."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
