Whenever a particular user opens Outlook, the application prompts him to also sign into "Management" which I have tracked down to an old site built w/Sites in Office 365. However, I have not been able to figure out how to remove this feature, as it is no longer used, nor how to prevent it from opening a dialog box and prompting for credentials.
Has anyone else heard of this before? Does anyone else know how to handle/remove this? I'm guessing there's a nice/easy PowerShell way to do this.. otherwise, maybe it's in the Admin console and I just haven't discovered it yet...
Thanks in advance!
EDIT: It has crossed my mind to make his mailbox "shared" and then delete his user, create a new user, add back the shared mailbox and go from there (figure it would unhook).
