One of our users shared a calendar while one vacation. he is now back and wanted to unshare it, but those people he shared it to can still open it. I've done my research and seem like this settings are correct so no one can view it. I made a test user with his same permissions and shared the test calendar with myself. I can view it. Unshared the test calendar > I can still open it.
After some testing it found out that I really wasn't opening the Test Users calendar anymore. I believe this because I made new appointments on the test user's calender and I could no longer see the new appt. Our outlook is set to use Cache Mode. What I'm guessing is happening is when a user1 shares his calendar with user 2, user 2 opens said calender and user1 calender is downloaded to the .OST file of user2 outlook. After user1 unshares his calendar, it looks like user2 can still open it becuase he is opening via his .OST file.
Can anyone confirm this? If this is the case how can delete an already opened calendar? I don't want to go around and deleting .OST files from computer. That would take for ever and would only be temporary fix because it would happen as soon as someone shares their calender again.
