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…

Quotes from Members

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

Pros

"We've been using Exchange as an email platform. Our clients require multi-country, multi-regional email collaboration with controlled mail flow. The most valuable feature is the capability of message tracking and the protection of user data."
"The initial setup is very simple."
"It's pretty easy to manage."
"The latest versions have gotten much better about balancing the load on the backend."
"Overall, I am satisfied with the product."
"We have found the solution to be stable; there are no bugs or glitches, the performance is good, and we don't worry about it crashing or freezing."
"It integrates well with other tools."
"Microsoft Exchange is a powerful solution. It can easily integrate with Active Directory and other business applications. It does not require any training, it is flexible and simple to use. When comparing Microsoft Exchange to other solutions, such as Lotus Note, it is more straightforward for business."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
"The Zimbra Collaboration's most valuable feature is web access."
"The web interface is powerful and easy to use."
"The most valuable feature of Zimbra for our team's productivity is its efficiency in handling email communication."
"We can control all the data in my IT infrastructure."
"The configuration is simple."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"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."
 

Cons

"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."
"I think that improvements should be made in creating greater abilities for Microsoft Exchange in terms of Research and Development."
"If it was the same product, and slightly cheaper, that would be amazing."
"Currently, its administration is too cumbersome. It's unwieldy. It's slow. It consumes too many resources. Configuration needs to be much more streamlined and administratively automated."
"The default storage capacity is too small."
"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."
"After 2022, users of Microsoft Exchange have to migrate mailboxes to Microsoft Exchange Online, and what I'd like to improve is for Microsoft to publish more on-premise versions for customers using Microsoft Exchange."
"Deployment should become a bit easier, the process is a bit complicated. You have to have done it one or two times before you get it right. The first time you do it, it won't be perfect. There are a lot of complications compared to Gmail For Business, which is a bit easier when it comes to configuration."
"The solution could improve by making it easier to use."
"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."
"I would like to see a Microsoft schedule function added."
"The solution could improve by making it easier to use."
"It would be great if a group chat feature were created to allow for a team environment."
"The new patches are, at times, not so good, so we don't install them, causing the tool to be not so stable overall."
"I would like to see a Microsoft schedule function added."
"Zimbra is not very stable, but it's okay."
 

Pricing and Cost Advice

"They are flexible when it comes to pricing, unlike most of the other vendors I have dealt with."
"The solution's pricing is fine...I do think the tool offers value for money."
"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."
"Compared to the other options in the market, the licensing costs attached to Microsoft Exchange seem reasonable."
"Since my company is on Microsoft Cloud, we pay for the licenses per user. Compared to volume licensing, I would say the present licensing cost is not expensive."
"It is not expensive."
"Licensing fees are paid monthly."
"The platform has a reasonable price."
"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"
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"Zimbra Collaboration is less expensive than Microsoft Exchange. Zimbra works for small companies because it is not expensive. Zimbra Collaboration has more security tools than Microsoft Exchange. If you are choosing between Zimbra Collaboration and Microsoft Exchange, you have to take into account the cost of security tools with Microsoft Exchange. When you purchase Microsoft Exchange, you will also have to purchase tools for security, which adds to the cost. The migration from Zimbra Collaboration to another email solution is very simple and easy. Migration from Microsoft Exchange to another email solution is very difficult. Microsoft doesn't allow migration that easily. In fact, you have to pay for tools to do that. You have to buy some expensive tools to migrate."
"The solution is not expensive compared to other products."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"The solution is competitively priced."
