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.

"One of the most valuable features of Microsoft Exchange is its security."

"The email management system is very easy to set up, configure, and use."

More Microsoft Exchange pros

"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."

"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."

More Zimbra Collaboration pros

Cons

"Its stability is not so great. We can't move mailboxes because of a corrupt file or random issues, which causes headaches."

"Microsoft Exchange is a little bit difficult. The challenge lies in the cloud implementation."

"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."

"There is a problem when scheduling an event for the whole day."

"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."

"At the end of the day, the biggest area for improvement is having better and more knowledgeable support technicians."

"The main problem with Microsoft products is that we're constantly required to install patches and fixes."

"One major area for improvement is the need for repeated authentication when running a meeting."

More Microsoft Exchange cons

"Zimbra must improve its solution to make it easy so that the users don't have to use webmail to connect to their accounts and log in to webmail every time. This is something that is lacking in Zimbra Collaboration. They should provide a better way to easily connect email applications on the desktop to the Zimbra server. They should also try to have more functionality for storage management, like Microsoft Exchange. Currently, the management of the email data must be done manually in Zimbra Collaboration, which we are finding very difficult. They should provide a way to save emails so that you can have more space on the server and storage. Because of the lack of this functionality, we are planning to migrate to Microsoft Exchange. Microsoft Exchange provides a better way to manage storage than Zimbra Collaboration. You cannot have a mail solution without storage management because emails will always increase. Zimbra Collaboration also needs tools for management. More back-office tools are required to manage the whole mailbox and space. You don't only manage emails but also the documents attached to the emails. Therefore, you require tools to select and decide what do you want to save or how do you want to free up space in your infrastructure."

"Zimbra Collaboration is expensive, and there is no perpetual license option."

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

"It does have a few bugs. However, they are small and can be worked around."

"The solution could use more integration with third-party tools."

"The installation is not straightforward, it can take two days for the full implementation."

"The antispam and antivirus features are hard to understand on mobile devices."

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

More Zimbra Collaboration cons

"It is not expensive."

"The price of Microsoft Exchange is reasonable."

"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."

"The solution's pricing is fine...I do think the tool offers value for money."

"Exchange is better for medium to large businesses because it can be quite costly for SMB, which may not need all the options the product provides."

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