Apple Mail 8 shows welcome screen on every launch
howapple - hello
Yes, but that did not make a difference as well. I fully deleted `~/Library/Mail/V2` as well as `~/Library/Preferences/com.apple.mail.plist`, rebooted the system, re-added my IMAP account and had my ~50k mails re-indexed. This took about two hours but now Mail.app behaves as expected (at least in this case). Another poor Apple job in being verbose.
