We have been using the traditional GTM outlook add-in (not plug-in) and tray controls to create meetings, but they only use the default calendar and associate the meeting with the personal company email.
TL:DR - How do I change the Outlook plug-in's currently associated account credentials? I cannot remember if I told it to remember my login details, but even if I did there should be a mechanism to forget them and log in as another user. If you have OWA set as the homepage on the Access Gateway Enterprise Edition, then logout of OWA should trigger the logout from the VPN session. While the plug-in works to have the shared calendar 'own' the meeting, I cannot see a way to change the associated GTM account and log in another user. This article describes how to ensure Outlook Web Access (OWA) logout triggers VPN session logout of clientless VPN using the Responder Feature. The goal is to have an Office Admin create meetings on the shared calendar using one of our multiple GTM accounts so that if they leave the company (recently happened) all of those appointments are not tied to their personal company calendar. I am testing out the Outlook 2013 plug-in and it works well for scheduling appointments on a shared calendar.
