1. During email migration from @berkelapg.com to @berkelandcompany.com, a generic error was encountered (screenshot attached) that indicated the user couldn't be updated.
2. The cause of this is the same kind of profile corruption that we're used to seeing in pre-Office365 versions of Outlook, so the solution is similar:
a. To force recreation of the profile, change the Set As Primary address from the problem @berkelandcompany.com to an undesired primary account (e.g. @onmicrosoft.com)
b. Save the change then reopen the Edit dialog
c. Under User ID at the top, ensure the @berkelandcompany.com is selected in the domain portion of the User ID, then Save that
d. Next, you should now see the @berkelandcompany.com address listed again as an option to Set As Primary - go ahead and Set As Primary and Save
3. The user account should now show properly with the @berkelandcompany.com domain with no errors.
