Suddenly, Evolution can't connect to Exchange server

[Matthew Saltzman]

It seems like it started after the latest round of updates.  If I have
an Exchange account in Evolution, Evo opens a dialog box prompting for
the Exchange password when I start it up, and freezes instantly.  I
can't type in the box or do anything else.

Any idea what would have affected this?  The updates, from yum.log were:

Annoyingly, Evo attempts to connect to Exchange whenever I start it, if
the Exchange account is active.  Starting with the --offline option
doesn't stop that.  The only way around it is to remove the
evolution-connector RPM and start Evo.  Then the Exchange account is
converted to have no server type.

Outlook seems to work OK on my Windows machine.  I don't think anything
changed on the server side.
