Subject: Recovering missing Mail folder from TimeMachine backup
March 10, 2021 11:25 EST AMTopic starter
Problem: have migrated to a new Mac, but for some reason the Migration Assistant failed to bring over the email (all other files were brought over successfully). I suspect it was due to the brand new IMac arriving (surprisingly) with Catalina installed, and the old Mac had already been upgraded to Big Sur. (We've upgraded to Big Sur on this new Mac post-migration, but found the emails still missing).
Was able to add the Gmail account from scratch and download all the server mail, but the "On my Mac" mailboxes (containing thousands of emails) are missing. Retrieving them from TimeMachine has been a failure.
When I bring the Mail viewer to the front and enter TimeMachine and pick at date, it sits and never reveals the email state of that day. We've let it sit for a couple hours, and it just doesn't go back in time. Alternatively, when I open the ~/Library folder in the Finder and and initiate Enter TimeMachine, it shows that there is no "Mail" folder that was backed up. Every other folder in ~/Library seems to be there, with "Mail" the only one missing. Have tried multiple dates going back months, as if the Mail folder had been excluded from TimeMachine (but it wasn't).
Any ideas how to retrieve these "On my Mac" mailboxes?

Do you have any offsite backups?

I didn't want to complicate it and just present the essence of the problem. But I'll go into the details.
