Comment 36 for bug 34199

OK...same trouble here. Trying to put a common thread. My Fiesty-Gutsy upgraded box running Evolution 2.12 was doing the same. I deleted the folders under ~/.evolution/mail/exchange/. Exchange can only be configured for one account. For my part I had 3. I monitor the windows system administrator's box. I tried (apparently twice) to make an exchange box with that account. It failed, and I configured the admin box with an IMAP account. The backend seems to pop when I attempt to forward mail from the Admin box. I will let you know how it works after I noodle around for a while. Right now seems to be back to good.
