Reliable email service has supported consistent communication and improved user training

I do use Cisco Secure Email, Grafis, and Proofpoint Email Protection when needed, but we were using Proofpoint before, and we are no longer using it. I am currently using Microsoft Exchange as our email solution. We are a client of Microsoft; there is no partnership between my company and Microsoft. My experience with Microsoft Exchange is as good as the generic email. I do not use Microsoft Exchange to synchronize emails across devices, and it is not part of my workflow. The protocols I mostly use with Microsoft Exchange for integration are SMTP. I do not use the shared calendars feature in Microsoft Exchange. Data loss prevention is something we are not really using or utilizing at the moment. My overall review rating for Microsoft Exchange is 8.

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

"The most valuable feature of Microsoft Exchange is the collaboration tools."

"The most beneficial aspects of Microsoft Exchange are that it is solid, dependable, and reliable."

"Internal communication stability within Exchange is ensured by the stability of the internal network which is guaranteed by default."

"Microsoft provides you with an ease of control and management and sets certain expectations from the software that you can't have if you implement other, cheaper solutions that are likely to be more difficult to manage or that are unable to adapt to new demands."

"In general, this is a good product and I am happy with it."

"Microsoft Exchange is a user-friendly product that is easy to manage and configure."

"The most valuable feature of Microsoft Exchange is its ease of use."

"Customers can benefit from this new pricing model because it's expensive, and now with the subscription, they can budget for this."

More Microsoft Exchange pros

"Zimbra Collaboration's best feature is its compatibility with Microsoft's ActiveSync protocol, which allows users to use Outlook on Windows or MacOS."

"Zimbra Collaboration is mainly used for messaging, emails, calendars, video conferencing, and document sharing."

"For an SMB, it is a recommendable email solution."

"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."

"The configuration is simple."

"The backup and storage management features of Zimbra Collaboration are valuable."

"Good email solution and it's open-source."

"One of the most valuable features involves the solution's automatic backup, which I find to be pretty simple and straightforward, and obviates the need for additional software."

More Zimbra Collaboration pros

Cons

"They could continue to improve the consolidation and integration of mailbox services to make them more flexible, easier to deploy, and more manageable."

"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."

"Sometimes we don't get support quickly enough - for example, if there's some global hacker attack, we don't get served as quickly. The skills of the technical staff can also vary, and Microsoft could perhaps improve their training."

"The solution could be more secure."

"We are not able to use Microsoft Teams due to connection issues. Thus, the product integration with Teams could be improved."

"We've had some issues getting responses from Microsoft support lately, as they seem not to be very interested in the Russian region nowadays."

"The solution is stable, but it could improve. It's crashing if there is a big mail database. The Zimbra solution is better in this area."

"An improvement would be to combine Exchange and Teams so that emails, calls, and chats can be integrated into one window."

More Microsoft Exchange cons

"Because of the lack of this functionality, we are planning to migrate to Microsoft Exchange."

"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 security issues."

"File sharing permissions with Nextcloud integration need improvement."

"They should enhance its online meeting features."

"The log files need to be improved; they need to show us more information because a lot of detail is lacking and that's not very helpful or insightful."

"There are some bugs we found that could be fixed."

"There are security and performance issues which is one of the concerns of using an open-source product."

More Zimbra Collaboration cons

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."

"This solution is expensive."

"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."

"The price of Microsoft Exchange could improve. In Egypt, the price keeps increasing."

"Microsoft Exchange is a very well-priced solution."

"Licensing costs for Microsoft Exchange have increased, but are still fair. For some users, the cost is high considering the number of functions and features they will use."

"We can get Exchange in the cloud along with the Microsoft 365 license."

"There are different prices depending on the customer's use cases and amount of users. The price of the solution could improve."

More Microsoft Exchange pricing and cost advice

"The price of the solution is low."

"The solution is competitively priced."

"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."

"The solution is not expensive compared to other products."

"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."

"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."
