My way (I hope it's helpful, sorry if not) is that I only trust my local maildir that I sync across my machines and back up multiple times a day using rsync. I only use the mail providers' interfaces for mobile and web access as read-only if needed, any manipulation happens on the local maildir files.
For this reason I do two-way isync (Expunge Both) on INBOX, Junk Email, Drafts only. I process and sort my inbox locally into various folders (recently explored macros in Mutt, so this got quite a bit faster now), and sync the sorted folders only up with isync (Create Far; Sync Push). E.g. I recently learned that Workplace set O365 to only show via IMAP the freshest 5000 mails in any folder which could be an issue I believe if I tried a two-way isync on such a mailbox. The system seems to be working fine but happy to learn about potential flaws!
