Service restored at 6:00 p.m.: All client services (desktop clients, mobile devices, web applications, and IMAP) are now successfully accessing the Exchange email and calendaring service.

Service issue updated at 1:05 p.m.: OIT and Microsoft are still actively investigating issues accessing Exchange from off campus from various desktop clients such as Windows Outlook clients, Outlook 2011 for Mac clients, and Apple Mail. The workaround remains logging into your account from OWA (Outlook Web Access), which is available at, or accessing your account from a mobile device.

Service issue upated at 11:15 a.m.: If you are unable to access Exchange mail and calendaring service due to "Exchange Web Services" issues referenced below, a workaround is to log in via OWA (Outlook Web Access), available at

Service issue updated at 10:45 a.m.: IMAP client connections to the Exchange service have been restored. Mobile clients, Windows Outlook desktop clients, and web application clients are functioning normally. However, OIT and Microsoft are still investigating issues with "Exchange Web Services" clients such as Apple Mail and Outlook 2011/2010 which are not able to access Exchange from off campus (on campus connections via "Exchange Web Services" clients appear to be working).

Service issue reported at 8:05 a.m.: Due to the planned maintenance work that began this morning for the purpose of bringing the Microsoft Office 365 servers into the current Microsoft 2007 production environment, IMAP and Microsoft 2011 for the Mac client access services are not able to connect to OIT's Microsoft Exchange service. The vendor, Microsoft, is engaged and is working with us to diagnose these issues and help restore functionality. More information will be posted here as it becomes available.
