Office 365

Known Issues

Known issues related to the Outlook 365 migration are outlined below, along with any workarounds available.

eScheduler Users - The eScheduler application is not compatible with Office 365 at this time.  If you receive notice that you have been scheduled to migrate, please contact IT immediately.  We are working to address compatibility issues, and hope to have this application working with Office 365 very soon!

Sorted Address Lists

Sorted address list views that were available when using Exchange on-premise, are not available in Office 365.  If you miss the sorted address list view, there is a work-around.  If you click on the Address Book, then click on Advanced Find.  Enter the correct Department Name in that field on the search form, and click OK.  The address book will be searched, and all objects matching the Department Name entered will be displayed. 

Calendar Delegation

Calendar and mailbox delegation cannot be done between a user that is on Office 365, and a user that is using Exchange 2007 or Exchange 2010 "on premise".  Calendars can be shared so that others can view free/busy time, or meeting details on your calendar, but edit permissions cannot be assigned.  To grant view only permissions to a calendar on Office 365 with a user that is using on premise Exchange, use the Share Calendar function.  Assigning permissions in the properties of your calendar is no longer supported.


Many of our users have permissions to send email for another user or mailbox.  This is true for many of our shared mailboxes, as well as managers that have delegated this ability to their assistants.  In order for send as permissions to work using the same Outlook profile, both mailboxes must be either on premise, or in Office 365.  If the mailboxes cannot be hosted on the same system, the supported work around is to open the other mailbox in a separate Outlook profile.

Accessing Additional Mailboxes

If you use your Outlook desktop client to access shared mailboxes, you will need to remove them and then re-add them after your email account has moved to Outlook 365.  Instructions for doing so are provided below.
