Hello. I always encountered this strange behaviour after a new installation of Mac OS X. I used Mail for two Google Mail accounts, saved the Users/ME/Library/Mail folder to an external hard drive, for putting it back after a I installed my system again. So, now that I have done it, still the Welcome to Mail screen appears where I have to input my data for my account. I did so, but even the import mailbox function did not function properly. So how can I use my account for Mail, that I saved to an external drive? I used and use Mac OS 10.5.5 and Mail 3.5. Thanks in advance.
