I just upgraded, and like a few other users I had issues with Evolution email after the upgrade from 11.04 to 11.10 and then 12.04. I know to make backups, but in this case I stupidly didn't think that the program would be changed (Firefox wasn't modified at all), and so I failed to make a backup.

Three days later I am still having issues, and recovering the emails is proving to be difficult with only partial recovery or it not working at all.

My question is, can I add in some source to use the 11.04 version of Evolution, since that version was working fine and would know what to do with the current files (Inbox, Outbox, etc.) I also noticed that Evolution's restore feature said it changed the way emails are handled, so it seems like a downgrade could put everything back to normal.

Worst case scenario, I start over, but I wanted to try everything first. Thanks in advance! I'm also open to any suggestions for restoring the old emails files to the current version of Evolution.
