Helps with email services and communication with internal and external contacts
Everything is useful. The only useful thing Microsoft Exchange could do is give us more of a discount on pricing because it's so expensive. Regarding the calendaring functions of Exchange, there is a problem when scheduling an event for the whole day. When you click the whole day event, the scheduling doesn't really work. For example, if I schedule a meeting with you and block your whole day, instead of just putting a time from morning to afternoon, other people can still block your time, which results in double booking. It's kind of a bug that allows people to double-book. So, the scheduling isn't working properly yet. We also faced challenges with backup services. You need to use a third-party backup solution to back up the whole Exchange server properly. You can't use the native Windows backup services. It's like they're forcing me to buy another product, which means additional costs. The backup solution and the double booking issues. If Microsoft Exchange can fix these two things, then it will be very good.

Effective collaboration achieved with versatile features and good customer service
There are always improvements needed. My personal issue with using OfficeSuite and the Exchange Server is that one has to cobble together a whole bunch of different applications. Therefore, a lot of scripting and programming knowledge is necessary. I am not an IT person; I am an educator, a trainer, a user. I want to get the work done. However, I find that the Exchange Server and possibly the way our company has set up access permissions require extensive programming knowledge. It might take six to eight weeks to get a programmer's time to build something, whereas I can use something like Smartsheet that will do everything I want without needing a programmer. Smartsheet is more end-user friendly compared to a Microsoft product. Microsoft believes an expert IT person should manage everything, however, I want to manage things on my own in a simplified way. That is not easy using the Exchange Server or Microsoft Office. It is not end-user friendly for development, and a programmer is needed. Once set up, using them as an end-user is fine. I find that the automations are not robust, and the FedRAMP systems are not robust. I have a few issues with Exchange and Office, but there's nothing I can do about it.

Deploys quickly and has a good web interface
Zimbra Collaboration has a good web interface When it comes to administration tasks like configuring specific filters or group signatures, I have to dig into the configuration since there's nothing in the graphical or web interface. The solution’s forums don't have much information or…

Pros

"It has a feature that allows you to retain an email and recover it as an administrator. When you activate this feature, even if a user deletes an email, the email is still in the system, and we can retrieve it as an administrator. It is a very useful function. We turn this feature on for some of the mailboxes because we need to keep all the records. I like the way emails are classified in this solution. It makes it really easy to take a look at the most important messages. This is a really good functionality. Some of the emails directly exchanged with you are marked as important and shown in one tab, and everything else is in another tab. We usually don't have any issue with Exchange. It can be integrated with different solutions."
"Microsoft Exchange's most valuable feature is that it's old-fashioned communication, meaning it's good for people who aren't able to work comfortably in a cloud environment."
"It is very well integrated with other Microsoft programs, teams, and so on. They work well together."
"It is a very stable tool...It is a very scalable tool."
"The most valuable feature of Microsoft Exchange is the email storage is on the cloud. We don't have to delete emails often."
"We have found it to be a stable solution. It is scalable and easy to install."
"It is a product that is simple to manage, and easy to use."
"Exchange is very scalable, it's one of the most important things about this software."
"It is a fantastic solution."
"Exchange Online's performance and stability are very good."
"Exchange Online's most valuable features are two-step verification and security."
"It's pretty reliable. We haven't had any issues with it."
"Microsoft Exchange Online's resiliency is its most valuable feature."
"The benefits are widespread and effective communication. We use Microsoft Teams for meetings within and outside our organization. Additionally, Teams can be used for chat, allowing us to track communication and see user activity"
"Microsoft Exchange Online is an easy-to -use email solution."
"The product was simple to use."
"Zimbra Collaboration is light to manage. It works on the Linux operating system, which is far better to manage than Microsoft Windows. Microsoft Exchange works only on the Windows server. We prefer working on the Linux server for security reasons and ease of management. Zimbra Collaboration also has some integrated tools for security. It some modules to fight malware. These modules are not very powerful but are still doing a great job. Microsoft Exchange doesn't have a basic module. You have to purchase a security solution and add it to the solution. The cost of Zimbra Collaboration is one more reason for liking it. It is also very simple to migrate from Zimbra Collaboration to another email solution."
"The Zimbra Collaboration's most valuable feature is web access."
"The configuration is simple."
"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 logs, troubleshooting, and tracking we have found to be the most valuable features. We have any issues with lost messages the features are useful. It is very easy to track and log."
"We can control all the data in my IT infrastructure."
"The backup and storage management features of Zimbra Collaboration are valuable."
"One of the premium features was customized rooms tailored to the collaboration needs. Many of the clients customize features such as organization logos and scanners."
 

Cons

"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. Having more security is another room for improvement in the solution, particularly for mailboxes that develop the Exchange Edge rule to protect internal mailboxes. What I'd like to see from Microsoft Exchange in the future is for Microsoft to still update the latest, existing version which is 2022. I'd like Microsoft to still push more cumulative updates for Microsoft Exchange 2022."
"In our current situation, the disappearance of sanctions would be a tangible improvement. We are basically cut off from technical support and it's very difficult to obtain any updates."
"An area for improvement would be the convenience of working with Azure services from Exchange on-premise installations."
"Exchange can be a little finicky, sometimes, or flakey. Last week, for example, I had gone into my calendar to check on some briefings that I had established, and then went back into my inbox, and suddenly the view had changed. I had no idea what it was that I had done, and I couldn't figure out how to get that view back. I took a productivity hit as a result of that, trying to fix it, due to the fact that it just wasn't what I wanted. It wasn't what I was used to working with. Two different tech support people had to work with me in order to get the view back to what I wanted just so I could be productive."
"They keep making all these changes, and our system was down for four or five days. They finally got it up, but there are still lots of quirks."
"At the end of the day, the biggest area for improvement is having better and more knowledgeable support technicians."
"In terms of configuring the product, that's definitely an area in which they can make some improvements on."
"In terms of probability, every now and then there are changes coming and going. The changes are not that frequent because every month they got updates back, so that is an issue."
"The solution’s technical support could be improved."
"The cost is very high, and not every customer can afford licenses."
"Technical support can be improved by shortening the response time and increasing their knowledge."
"This solution involves a lot of work for an administrator. It is not always easy to find exactly what you are looking for within the system."
"There is room for improvement in terms of security, as it could be better."
"My personal issue with using OfficeSuite and the Exchange Server is that one has to cobble together a whole bunch of different applications. Therefore, a lot of scripting and programming knowledge is necessary."
"The price could be an area of concern for many."
"In terms of machine controls, it was very confusing, and some of the administrative parts will be done from the control, but in online writing mostly we can handle everything."
"It would be great if a group chat feature were created to allow for a team environment."
"The support was lacking in my experience. However, recently the support I received was good. Perhaps they have improved."
"The solution could improve by making it easier to use."
"Zimbra Collaboration's video conferencing could be improved."
"It does have a few bugs."
"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 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."
"File sharing permissions with Nextcloud integration need improvement."
 

Pricing and Cost Advice

"Compared to the other options in the market, the licensing costs attached to Microsoft Exchange seem reasonable."
"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."
"Microsoft Exchange is a very well-priced solution."
"The platform has a reasonable price."
"There are different prices depending on the customer's use cases and amount of users. The price of the solution could improve."
"The price of Microsoft Exchange is reasonable."
"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 product pricing is reasonable if you utilize its full suite of features."
"Initially, we had issues with the licensing agreement, but we worked it out with Microsoft."
"We have yearly licensing costs."

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