Missing Mail folders
I recently had to wipe my MacBook Air and reinstall everything. I'm now in pretty good shape, except my Mail is missing some emails that I had in storage folders. Entire folders are missing.
One thought that occurs to me is that I have three different Apple ID accounts. Is it possible that different emails and folders are associated with different accounts? And if so, is it possible to pull in emails into Mail from three different accounts and combine them all?
Or am I on the wrong track? What else should I do to find and restore these missing folders?
