Periodically, I have problems connecting to our Exchange server using Evolution. I’m not really sure what causes it but it appears to be a problem retrieving new messages. The message I get in the GUI is that “Evolution lost the connection to the Exchange backend server.” Restarting Evolution does not correct the problem, not noes rebooting the system entirely.

Fortunately, I can correct the problem with the following procedure.

Close Evolution, and in a shell, execute the following:

evolution –force-shutdown

cd ~/.evolution/mail/exchange

rm -fR *
