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.

Pricing and Cost Advice

"This solution is expensive."
"Compared to the other options in the market, the licensing costs attached to Microsoft Exchange seem reasonable."
"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."
"There is an annual cost to use Microsoft Exchange, and the price could be less expensive."
"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."
"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."
"Microsoft doesn't have a unit price, it's based on the quantity, and they offer great discounts."
"Its price is okay."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"We do not pay for licenses to use this solution."
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."
"The price of the solution is low."
"Zimbra Collaboration offers a good price-to-feature ratio."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
