Q: IMAP email accounts gone in Mail after Sierra upgrade
I have three main email accounts I use, all set up as IMAP accounts on my companies server. I access them with four devices - 2013 iMac, iPhone 6, iPad (3d gen) and a 2010 MacBook Pro. I did the Sierra upgrade on the MacBook Pro and while my email seems to be functioning normally (Inboxes and messages are still there - if I delete something from a box on the MBP, it shows up in the trash on the other devices, mail received as normal, etc), when you go into preferences->accounts the IMAP accounts are no longer showing up, although I do see them as POP (which they were originally set up as, but those have been deactivated when I switched everything over to IMAP and I just haven't deleted them. They are still showing as inactive). I also have an iCloud IMAP account and that shows up like normal.
Any thoughts?
MacBook Pro, OS X El Capitan (10.11.4), 2012 Model

It sounds like Sierra Mail pulled your data from the old V2 folder. If you have no V2, it completely removes V3 and moves everything into V4.
If you look inside the folders with the cryptic names, you should be able to tell what account it is by the folders. You can also drill down in the Inbox and view a message to see which account it was sent too.
