Comment 4 for bug 653503

I can also confirm, 10.10 x64, Evo 2.30.3, Exchange Server 2003.

When I kill it and reopen, clicking to expand the Exchange account doesn't work - it immediately snaps back to collapsed. If I open the preferences, edit the account and go to the Exchange Options tab, my Out of Office message and folder sizes are available, so it has connected successfully at least once - but once I click save, it hangs before I can close the preferences window.
