imap-backup VS got-your-back

Personally, I use https://github.com/joeyates/imap-backup to archive all my emails and then only keep them on the remote server for as long as I need to (basically until I read them and respond or download an attachment into https://docs.paperless-ngx.com )

I use imap-backup to backup my MailCow email boxes.

You'd need an IMAP backup tool. For example: https://github.com/joeyates/imap-backup . Add it to cron if you want it to backup periodically.

Here's a bad idea that may work. https://github.com/joeyates/imap-backup. I used something like this when we migrated from ridiculous email system to exchange. However the clock is ticking on this option as it doesn't support modern authentication.

Got your back is the right tool https://github.com/GAM-team/got-your-back/wiki

alternatively, give them access to the user account and have them use Got Your Back ( https://github.com/GAM-team/got-your-back )

This tool from the creator of GAM will allow you to purge a mailbox: https://github.com/GAM-team/got-your-back

THe information it gives is inaccurate and it can sometime just stop. never had a good experience with it. for a couple accounts I'd go for GYB - https://github.com/GAM-team/got-your-back

GYB - gmail backup tool (I use the linux version, but it does have a version for mac).

if you don't want to spend you can also get only emails with "got your back". https://github.com/GAM-team/got-your-back

Either Google Takeout for everything, or GYB (got-your-back) https://github.com/GAM-team/got-your-back for email. You can try GAMADV-XTD3, but it can be super complex and I’m not sure if a standard account can use it or if you have to be super admin.
