The biggest issue with Microsoft Exchange is its high cost, especially in pricing for license upgrades and expansion to more users.

The quarantining is not fantastic because it lets a lot of spam through, and when it is notified of spam, it does not particularly alter its behavior quickly.

Featured Reviews

Owner at Marinov
Centralized email accounts have streamlined routing, security checks, and long-term organization
While using Amazon WorkMail over time, I haven't encountered substantial disappointments, but there have been usual glitches with the web interface. For instance, while the service is generally 99.5% perfect, I experience issues like the folder structure I set up sometimes not remembering the state of expanded and collapsed nodes after refreshing the page. This lack of persistence in which nodes are collapsed or opened can be frustrating. However, since it's a minor technical issue, I doubt the average user would notice it. If Amazon WorkMail were not discontinuing, I wouldn't think there is much to improve or enhance about it. It is standard enough and easy to use, and any glitches are minor, not worth evolving or disrupting its current functionality. As for whether the user interface is intuitive and if I'm satisfied with its flexibility and customizability, there are some minor features lacking, but I don't feel a need for changes since it works as designed. The most crucial aspect is that I can set up my address book with the complex organizational structure needed for the accounts connecting to AWS. The lower-level functionalities suit me well enough. Other services often have customizable views of email representations with senders, subjects, and even snippets of content. While my external application on mobile can show customizable lines with my email list, Amazon WorkMail does not offer that feature. I don't really need it, but it would be a nice addition for power users.
