Microsoft Dynamics CRM Online uses Windows Live ID service credentials to control access to the application. To change the user's sign in, you must update the user's record and send a new invitation. The person will not be able to access this organization until the new invitation is accepted and the person has signed in with the new Windows Live ID service.
Note If the new e-mail address is not a Windows Live ID, then the user will need to make it one before signing in and accepting the invitation. A new invitation will be sent to this e-mail address.
The User record for this person will be updated with the new Windows Live ID and the Invitation Status field will be reverted to Invited.
