If your day is split between a work mailbox, a Gmail account and a calendar elsewhere, a browser with six tabs is a poor headquarters. Zimbra Desktop pulls mail, contacts, calendar and tasks into one app on your Mac. It was built around the Zimbra platform, but it also connects to Gmail, Yahoo Mail and standard IMAP or POP accounts. Messages sync down, so you can read and draft offline and send on reconnect.

Key Features

• One inbox view for Zimbra, Gmail, Yahoo and IMAP or POP mail accounts
• Mail, calendar, contacts and tasks together in a single desktop window
• Offline access to synced messages, with drafts and changes sent on reconnect
• Powerful search, tags and filters to keep large mailboxes organised
• Familiar web style interface that mirrors the Zimbra web client closely

FAQs

Can I use Zimbra Desktop without a Zimbra server?

Yes. It also works with Gmail, Yahoo Mail and other accounts that offer IMAP or POP access.

Does it work offline?

Yes. Synced mail is stored locally, so you can read and draft without a connection and sync changes later.

Is Zimbra Desktop free to use?

The desktop client itself has long been offered as a free download, though your organisation may run a paid Zimbra server edition behind it.
