I had followed a guide about 6-8 months ago in the forum on using the powershell (I think it is called) interface to give myself as an admin access to remotely attach to a user's entire account via the "Exchange / Advanced / Mailboxes / Open these additi.. " feature in Outlook on the desktop so as to assist someone with a problem they were having.
I've just noticed that they user's account is still showing in my outlook, not only on my work computer which I was at when I set this up, but on my notebook and even the outlook on my new home computer when I set it to attach to my work email.
His name does NOT show up on the settings, it has no additional mailboxes to open. I'm wondering if I may have set something in the advanced mode which is doing this and if anyone can guide me through the undoing of it. I no longer need continual access to this person's email.
