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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"It is enterprise-friendly, and many organizations use it."

"Microsoft support is very good."

"Microsoft Exchange is stable."

"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."

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

"The technical support services are good."

"Using EWS support, we have created a custom UI to display meeting info on our local portal to utilize and manage meeting and conference rooms effectively."

"The latest versions have gotten much better about balancing the load on the backend."

More Microsoft Exchange pros

"VMware Zimbra is an enterprise-class E-mail, calendar, and collaboration solution, built for both public and private clouds."

"The Zimbra Collaboration's most valuable feature is web access."

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

"The product is very stable."

"The solution is easy to implement."

"Zimbra Collaboration has a good web interface."

"For a small company, Zimbra Collaboration is good because it is simple, inexpensive, and not very difficult to deploy."

"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."

More Zimbra Collaboration pros

Cons

"The filtering of spam needs significant improvement, as many spam emails are not getting detected."

"It doesn't work very well on a virtual machine. We had to move it around. There are also issues when you try to move it between computers."

"I think that improvements should be made in creating greater abilities for Microsoft Exchange in terms of Reasearch and Development."

"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."

"Its search functionality can be better. It is currently not really easy. It has the capability to search your mailbox, but it has some restrictions in terms of the number of results that you can retrieve. You can only get around 250 results. If you want to do a deeper search, you need to use different functionalities of the product. The policy that we have for handling emails is that we do not delete emails at all. If I insert the text that I am searching for in the Search field, it only retrieves a limited number of emails. To search for an email from 2010, I need to use different search functions to find what I am looking for. Microsoft can also improve its licensing for its products. Microsoft's licensing is not very easy to understand. It can sometimes be really complex to understand what you need to have in order to comply with Microsoft licensing."

"Sometimes the client part generates some trouble. It can be very slow, though this might be related to our company's installation and configuration rather than the product itself."

"In terms of Microsoft Exchange, I think maybe what can be done is to make it more user-friendly."

"Microsoft Exchange could improve by adding artificial intelligence."

More Microsoft Exchange cons

"The tool should improve its multi-cloud feature."

"The new patches are, at times, not so good, so we don't install them, causing the tool to be not so stable overall."

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

"The solution’s forums don't have much information or documentation on administration tasks."

"Some issues cause the solution not to function correctly or to cause downtime once a month."

"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."

"Zimbra Collaboration's video conferencing could be improved."

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

More Zimbra Collaboration cons

Pricing and Cost Advice

"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."

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

"Microsoft's licensing structure is too complex, but its prices are affordable, though not cheap."

"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."

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

"Compared to the other options in the market, the licensing costs attached to Microsoft Exchange seem reasonable."

"It's a little bit expensive."

"It would be nice if it used less resources to run on-premise."

More Microsoft Exchange pricing and cost advice

"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"

"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."

"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."

"The solution is competitively priced."

"We do not pay for licenses to use this solution."

"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."

"We pay yearly licenses for Zimbra Collaboration."

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