I have about 30 accounts that I have to migrate from IMAP based folder system to an exchange based system. Th desktops all run OSX apple mail.
I have access to all the credentials for all the accounts. There is currently mail being delivered to both sets of accounts. (not my fault, the hosted exchange accounts recongise the domain and deliver locally instead of to the main mail server).
In effect what I would like to do is run a script/app/program that checks account A and if the email is not in account B, move it over.
What's the best way to do this?
