GNOME Evolution LogoQuick Answer: Delete any related file ending in “.ev-summary” in the ~/.evolution/mail/local/ folder.  Make sure Evolution is closed before you do this.

Rant: Here’s my ordeal with this horrible error, at least to a noob in linux, like myself.  I couldn’t figure out why I was getting this error.  When I opened Evolution I would get a pop-up saying “Summary and folder mismatch, even after a sync”.  I thought it was my mail stored on my server, I have 4 pop accounts and I ended up deleting all the old emails 500+ each (Yeah I’m a pack rat).  It was literally driving me crazy because it wanted to redownload ALL my old emails.
