My organization has a master calendar set up for everyone to use. I currently have "Owner" permissions on this calendar. The issue is whenever I add a calendar appoint on this master calendar and invite myself to this appointment, normally you would be prompted as to whether or not you would like to add this appointment to your personal calendar. This does not happen for me. I get no prompt and do not receive an email for this invite. As far as I know, no one else experiences this issue.
