[Evolution] "Lost connection to back-end Exchange process"

[Peter Saffrey <pzs dcs gla ac uk>]

I use Evolution to connect to my work Exchange server, both from a home
machine and a work machine. I get the above error message quite
frequently, about 10 times a day at home and 2 or 3 from work. It means
that I can't receive new messages or read those that I haven't already
selected during a session. It requires an Evolution restart.

I'd like to provide a more comprehensive bug report, but I'm not sure
where I can find the proper log files. Can somebody point me in the
right direction?
