Integrated email security has improved phishing response and provides better threat visibility
Microsoft Exchange Online could be improved with more intuitive administration workflows, better troubleshooting visibility, and simpler mail flow analysis for complex environments. We would also appreciate more granular reporting, faster access to detailed message tracking data, and improved alerting around suspicious mailbox activity to help security and messaging teams investigate issues more efficiently. One area where Microsoft Exchange Online could improve is the administrative user experience. Some advanced mail flow, compliance, and troubleshooting tasks still require navigating multiple Microsoft portals. A more unified management interface and deeper integration visibility across Exchange, Defender, and Microsoft 365 security tools would make day-to-day operations more efficient for administrators and SOC teams.

Quick solution, but not very user-friendly or suitable for collaboration
It's not a good solution for collaboration. We're using it because of the price. It's not very strong or comparable with Office 365. An additional feature I would like to see is the ability to connect from different devices. Zimbra could be more user-friendly and deploy security rules. The integration with Outlook could be better to share agendas.

Quotes from Members

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

Pros

"It has helped us because we don't have to worry about servers crashing."
"Overall, technical support is very good."
"The overall usage was all good."
"The product is stable and provides good performance."
"The product enables us to have remote meetings."
"It is very manageable."
"Exchange Online is consistent. It's easy to deploy and scale out to all of our organizations."
"Exchange Online is stable, scalable, and easy to use and administrate."
"It's a fast solution."
"We implement this solution in our data centers, and we have high availability."
 

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 must provide better security features."
"The problem with Exchange is that the attributes aren't flexible enough. I'd like to see more interaction with Office 365 and tighter integration between on-prem Exchange and Exchange Online. There's still a disconnect between mailboxes and the cloud."
"The solution’s technical support could be improved."
"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."
"The efficiency could be improved."
"The price could be an area of concern for many."
"Despite being a Microsoft-certified trainer, I am lacking some information."
"It's not a good solution for collaboration. We're using it because of the price. It's not very strong or comparable with Office 365."
 

Pricing and Cost Advice

"We have yearly licensing costs."
"The solution's pricing is reasonable."
"They have raised their prices, and obviously, it hits our customers. Some of them are deciding to step back from Office 365. For customers who have bought the annual subscription, they are moving to the monthly subscription."
"It is a reasonable solution."
"I think that the price is a little high, especially considering that Google have a similar, free email solution."
"I have no opinion."
"The price is not competitive."
"The model is one which is pay-per-use go. There is no license. We are talking about per-user subscription-based use."
"It's an open-source solution so it's free."
