The user then attempted a reboot which I can only assume was hanging on Outlook and either forced outlook closed or the user accessed the power button to force a restart. When logging back in all related exchange profiles (there were several profiles from the same server) were no longer listed and seemingly deleted.
Unfortunately the users account of the events is sketchy so some of this is guesswork based on the user's usual actions/reactions but just in case profile deletion can occur from attempting to force this to end it is advised not to.
