Baulon, France
What it is
imapsync is an IMAP transfer tool for migrating or backing up mailbox accounts. Its command-line software performs incremental, recursive transfers between mailboxes, and a transfer can be stopped and restarted without generating duplicates. It runs on Windows, Mac OS X, and Linux; listed compatible providers and server software include Gmail, Office 365, Exchange, Dovecot, and Zimbra. The online service offers free mailbox syncs below 3 GB, while buying provides unlimited syncs of any size. Buyers also receive a visual interface that can be installed on a Linux server, though that interface does not yet work on Windows. The tool supports staged and tenant-to-tenant moves, including Microsoft 365 and Google Workspace. The software-only plan costs €72, paid once; Imapsync + support costs €144, paid once. It cannot migrate contacts or calendars, keep two active accounts synchronized in both directions, or transfer messages to or from a local directory. The maker offers a 30-day money-back guarantee for purchases and says there is no trial version.
