Quotes from Members

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

Pros

"On-premises Microsoft Exchange is good because it protects data privacy."
"It integrates well with calendar, scheduling, etc. It's easy for employees to make meetings and plan their agendas."
"The ability to share information, appointments, and agendas easily is the big value of Microsoft Exchange."
"Exchange is easy to use. It also has a built-in calendar for all the stuff I'm supposed to be looking at and doing. Exchange tells you if you have a doctor's appointment or a scheduled call. It also has a place to store and manage your contacts. If I want to add a new contact, it will put in information about that contact stored anywhere within the Microsoft Suite."
"Microsoft has a very good support team."
"It is a very stable tool...It is a very scalable tool."
"We have found it to be a stable solution, it is scalable and easy to install."
"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."
"The most valuable feature of Zimbra Collaboration is the cost."
"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."
"The solution is easy to implement."
"The product is easy to set up."
"The web interface is powerful and easy to use."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
"It is the best open source collaboration suite that I know, because it provides high availability and more performance than the other solutions."
"For an SMB, it is a recommendable email solution."
 

Cons

"Microsoft needs to make some modifications to meet the current needs of the environment."
"Nothing is perfect, that's why I am giving Microsoft Exchange a nine."
"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."
"There is a lot of spam email that comes in, so they should add functionality to help fix this problem."
"There is a problem when scheduling an event for the whole day."
"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."
"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."
"Its search functionality can be better. It is currently not really easy."
"Zimbra Collaboration's video conferencing could be improved."
"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."
"It does have a few bugs."
"We had a couple of issues with stability, but nothing that I couldn't work around or fix myself. Zimbra is a powerful product, but since VMware bought it, changes and bug fixes have been very slow in coming."
"It does have a few bugs. However, they are small and can be worked around."
"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 product must be more customizable."
 

Pricing and Cost Advice

"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."
"We can get Exchange in the cloud along with the Microsoft 365 license."
"Microsoft Exchange is an inexpensive application."
"The pricing is expensive."
"The solution is expensive to maintain because it requires frequent updates and ongoing server maintenance."
"It's working very well. There is no problem, but the price is not the best."
"The product pricing is reasonable if you utilize its full suite of features."
"Compared to the other options in the market, the licensing costs attached to Microsoft Exchange seem reasonable."
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
"The solution is competitively priced."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"The solution is not expensive compared to other products."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"We pay yearly licenses for Zimbra Collaboration."
"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."
"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."
