If the AD/Exchange password changes EWS doesn't detect that it's an auth issue. First you get an HTTP error about connections exceeded then the following SSL error "Unable to retrieve message. No response: SSL handshake failed" evolution-help-3.4.3-2.fc17.noarch evolution-NetworkManager-3.4.3-2.fc17.x86_64 evolution-ews-3.4.3-1.fc17.x86_64 evolution-data-server-3.4.3-1.fc17.x86_64 evolution-mapi-3.4.3-5.fc17.x86_64 evolution-3.4.3-2.fc17.x86_64
Thanks for a bug report. I moved this upstream as [1]. Please see [1] for any further updates. If possible, please CC yourself there, in case upstream developers will have additional questions. I think this is also related to bug #836740, where authentication issue causes high CPU usage. [1] https://bugzilla.gnome.org/show_bug.cgi?id=679303
