I have about 12,000 gmail emails many of which contain very important attachments.
I bought and read the take control book about Apple Mail by Joe Kissel, and am following his recommendations which is to use Apple Mail to backup my gmail account.
My problem is that Apple Mail email attachements keep getting deleted after some period of time (few days or weeks) and I have no clue as to why.
what I tried
I tried deleting, then adding the account multiple times. The attachments are there first, but then disappear after a few days or a week.
My Apple Mail accounts are configured (Mail → Pref→ Accounts) as download ALL attachments.
I don’t have any other apps which deletes mail attachments. I sometimes use Clean My Mac but always check that the delete mail attachments is turned off.
In Apple → About this Mac → Storage → Manage, I don’t see any setting which would delete email attachments
thanks in advance for your time and help
