This relates to the "Permissions" idea that has 143 votes as of now. There should be a default or permission of "all" for attendees on creating an activity/appointment/task. My assistant sets appointments and items for me on our calendars and I want both our calendars to look identical. Each time we set something on the calendar we have to manually check the attendees dropdown to ALL. If one of us forgets to select all, the default is to the current user and just shows up on that user's calendar. That causes issues. My assistant is new and still learning, and didn't select all on the attendee dropdown for an appointment he set up for me, so I was surprised when some clients showed up and said they had an appointment and weren't on my calendar because of this issue. I have this issue EACH time I have a new assistant. I tell them, but it's easy to miss it. It sure would be nice to have the attendee dropdown default to select all.
