Using Classic Outlook on Windows for personal email, calendar, and contact management
I experience kind of the same problem, but my problem is not related to locking the screen. It happens when I open existing meetings without changing anything.
Steps to reproduce:
- Open any meeting.
- Press "Scheduling Assistant" pane (...without doing anything else).
- Press (X) / close calender window.
- No changes was made, but dialogue box asks if you want to save changes. However, this doesn't seem to happen on all meetings. It seems to primarily occur when a ressource/room is attached to the meeting.
