how to archive IMAP email?

[SilverNodashi]

Hi,


We acquired a client with 2 mailboxes containing 10GB and 12GB emails each. Email archiving wasn't enabled on his account on the other server beforehand so I can't download email archives. Since he uses IMAP and has various folders in his mailbox, Outlook 365 doesn't archive all the folders automatically either.

Does anyone know how to manually archive all the folders so we can download it and free up some space on the server?

Hi SliverNodashi,

You can try to use this IMAPSync Tool ( https://imapsync.lamiral.info/ ) to duplicate all IMAP folders between two hosts running IMAP services. Should you want to "archive" this email you can opt to sync all folders into specific destination folder instead of just mirroring the contents as is. Be sure to check the commands before you execute as you can remove the source files using this tool.
