Some options related to your Outlook 2010 address book may have been changed when your account was moved to Office 365, such as your default address book is now incorrect. Take these steps to make your Outlook 2010 address book work more smoothly. - Outlook 2010 repeatedly prompts me for my credentials.
You may have credentials stored in a format Office 365 can't read. This is most commonly seen when you try to connect to a Resource account (Exchange Group Account, Room account, or Equipment account).

- To confirm removal of the account, click Yes.
- Now add that account back in by following these steps.
- Deleting that resource/group account:
