Just like MS Outlook, Zimbra Desktop is an email client available for both offline and online use. The Zimbra web client offers one of the best browser-based interfaces for connecting end-users to the information and activity in their personal clouds. Likewise, the users can enjoy the same powerful experience offline with Zimbra desktop client. It offers cross-platform functionality for Windows, Mac, or Linux desktops using IMAP/POP, CalDAV, CarDav.

Unlike Outlook, the Zimbra desktop client and server applications can be downloaded for free, which can be a game-changer when choosing between the two services. Although it wouldn’t be right to compare the two services as Outlook is far superior to Zimbra in terms of features and support.

Additionally, it is also possible to import Zimbra mailbox files (EML format) into the Outlook desktop client using the drag and drop functionality.
