I have migrated from a 2009 iMac (El Capitan) to a 2019 iMac running Big Sur. The new iMac's MacMail has no email accounts installed. It appears completely empty. How do I get them back?
iMac Line (2012 and Later)
If there are no accounts then I would just add account and setup again. If IMAP they should populate again. If you have any older emails you want back they would be in your library/mail/V folders that can be exported and then imported back into mail.
So, the next stage in my saga…
Big Sur's mailbox arrangement/content is nothing like the one I had on my old Mac - it's just a very basic; inbox, drafts, sent, junk and bin mailbox for each account.
Is there an *easy* way to recreate the mailboxes that I had before migration and populate them with the emails each mailbox had (I had a lot)?
It turns out that all the accounts were set as in active after migration. Resetting them as active and enabling Apple ID resolved the matter. Thank you anyway
