backing up/restoring a specific mailbox without using the profile
I have a profile containing three email accounts. It's huuuuge, but I was able to transfer it over to a second computer last year. I'd now like to update specific mailboxes on that second computer but don't want to have to recopy the profile.
Is there a way to update/backup/copy a specific mailbox for transfer to a second computer without having to use the profile?
Also, I'd like to be able to backup one of the three email accounts specifically. Is there a way to do this without using the profile? Thank you for any help.
