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."
"It is user friendly."
"Exchange's best feature is single sign-on access using the Microsoft Identity framework."
"The solution can scale up to whatever number of users one desires."
"Customers can benefit from this new pricing model because it's expensive and now with the subscription they can budget for this."
"The most valuable feature of Microsoft Exchange is the email storage is on the cloud, and we don't have to delete emails often."
"I find the Outlook client very valuable. It allows me to connect to the Exchange Server and send and receive emails easily. The graphical interface is user-friendly and has a good look and feel."
"The most valuable features of Microsoft Exchange are it is always online and has broad email and file-sharing capabilities."
"Good email solution and it's open-source."
"A lot of other products like Microsoft Exchange offer email or collaboration features, but they are not as fast as Zimbra."
"Network NG Modules are valuable to us."
"The most valuable feature of Zimbra for our team's productivity is its efficiency in handling email communication."
"For an SMB, it is a recommendable email solution."
"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."
"The web interface is powerful and easy to use."
"The product is easy to set up."
 

Cons

"More AI features would be good."
"There are limitations in terms of the number of emails that can be sent in a minute, which makes it a little difficult for the marketing folks."
"It is costly, so it depends on how much you want to pay."
"We would prefer to be able to manage the solution on the cloud."
"Microsoft Exchange could improve the price."
"In terms of what should be improved, they should probably move to a cloud option like Office 365. We would like to get this functionality without the need to deploy complex hardware and software solutions. This should be the next thing, making Exchange more related to Office products, which are more cloud-oriented, less on-premise or desktop-oriented solutions, like the direction Google is strongly moving towards."
"For new users, it might take them some time to get used to the product."
"Microsoft Exchange could improve by adding artificial intelligence."
"The product must be more customizable."
"Zimbra should provide a desktop client. Right now, we are using a web browser for accessing our emails. There should also be a desktop client."
"The new patches are, at times, not so good, so we don't install them, causing the tool to be not so stable overall."
"It would be great if a group chat feature were created to allow for a team environment."
"It does have a few bugs. However, they are small and can be worked around."
"The installation is not straightforward, it can take two days for the full implementation."
"It does have a few bugs."
"Zimbra Collaboration's video conferencing could be improved."
 

Pricing and Cost Advice

"Its price is very affordable, and basically, it is the standard of the industry. We have the Exchange 365 subscription, which includes the usage of Exchange Online. I don't know the specific cost, but it is the retail price of Microsoft 365 E3 licenses. Microsoft's licensing is not very easy to understand. Microsoft changes rules every other day, which makes it difficult for us to understand the licensing not only for Exchange but also for other products. It can sometimes be really complex to understand what you need to have in order to comply with Microsoft licensing."
"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's licensing structure is too complex, but its prices are affordable, though not cheap."
"Microsoft Exchange is an inexpensive application."
"They are flexible when it comes to pricing, unlike most of the other vendors I have dealt with."
"There is an annual cost to use Microsoft Exchange, and the price could be less expensive."
"The product pricing is reasonable if you utilize its full suite of features."
"We pay yearly licenses for Zimbra Collaboration."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"Zimbra Collaboration offers a good price-to-feature ratio."
"The price of the solution is low."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"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."
"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"
