Can guests see who else is coming?
Turn on Allow guests to see who’s coming if you want attending guests to see the list.
Find Allow guests to see who's coming in event settings or through Search setup and features.
When it is enabled, attending guests can see the households that have answered Yes, with names and a headcount. It does not show their contact details.
The default is on for new personal events and off for new venue events. Check your particular event before assuming either setting.
This permission is separate from Who can come, which decides who can answer the invitation.
