Offers flexibility and cost-effectiveness with multiple service options but could improve support and mobile features

There are many things to consider about email management in Microsoft Exchange Online. The online management is good, the storage is sufficient, and we use most of the features such as the custom rules in Microsoft Exchange Online, which we cannot find in any other email solution. That is a very good option, as we have many options to create custom rules in Microsoft Exchange Online. Regarding security features in Microsoft Exchange Online, we also use Defender for Exchange which includes the basic Exchange Online protection that has spam and threat controls. The use of Defender is beneficial for our security. The flexibility of choosing plans in Microsoft Exchange Online is good. We have chosen the best plan for our use, including multiple licenses such as plan one and business basics, which leads us towards cost-effectiveness, and the pay-as-you-go option is more flexible. Microsoft Exchange Online is very scalable.

One of the premium features was customized rooms tailored to the collaboration needs

Zimbra's strength lies in its individuality, and it should focus on leveraging its unique features rather than trying to emulate competitors. My organization has certified Zimbra technicians, so we believe we can utilize Zimbra certification. However, I was recently informed by Zimbra that no such certification exists. I have recently completed the test kit, and after the training, I will gain access to tickets. Therefore, if any clients are experiencing issues, we have a certified technical team available to provide support 24/7. This is how we can cater to our client's needs. I recommend Zimbra to small-scale and enterprise customers. Anyone, even those with 5 users, can opt for Zimbra. Overall, I rate the solution a nine out of ten.

Quotes from Members

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

Pros

"Exchange Online doesn't just do email, it allows for collaboration with inbuilt chat and calling facilities and document sharing."

"The online version is faster, as it is a cloud instance. We can have massive mailbox capacity: 100 GB per user, which is huge. We can't provision such capacity internally, as the company would get burnt out paying for mailbox storage."

"My primary use case for this solution is for clumping emails, and group emails according to the conversation."

"Microsoft Exchange Online is very simple and easy to use."

"Exchange Online plays a significant role in our business. It controls all our emails, so we'd be in a lot of trouble if we didn't have that. It's an essential product."

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

More Zimbra Collaboration pros

Cons

"The support from the vendor is fine. However, it could be faster, and some of the agents could be more knowledgeable, but it is a large solution, there's a lot of information that the agents have to work with. I can't always expect when I get connected to the first-level agent that they will know absolutely everything. Sometimes there's no replacement for pure experience."

"The solution's performance can be improved when you are trying to access it remotely."

"They should tighten their cloud security."

"The solution could improve by making the user interface better."

"The stability of the solution on Mac products has room for improvement."

"The solution is expensive."

"This product is too complex to use."

"Microsoft Exchange Online support can be optimized further. They should put some more efficient technical engineers to support end customers."

More Microsoft Exchange Online cons

"The solution could improve by making it easier to use."

"I would like to see a Microsoft schedule function added."

"In the next release, Zimbra Collaboration should include a security feature to allow access for mobile device administrators."

"Because of the lack of this functionality, we are planning to migrate to Microsoft Exchange."

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

"It would be great if a group chat feature were created to allow for a team environment."

"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."

"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."

Pricing and Cost Advice

"The price of the license depends on a lot of factors, such as the number of licenses and company specifics."

"The price is a bit high. It is especially expensive in the Indian market."

"I pay approximately $120 or $150 per year, and as long as I pay that amount, they will do regular updates so that I always have the most recent and greatest version of the application."

"There is an annual license required to use this Microsoft Exchange Online."

"We have yearly licensing costs."

"The solution costs $12 to $16 per user per month."

"There is an annual enterprise subscription to use Microsoft Exchange Online. The price is reasonable."
