Loop - Some Recipients wont be able to view or edit this.

We have been having some issues with Loop in teams when people create agendas.

Organisers were receiving an error that some recipients won't be able to view or edit this when creating notes / agendas with a loop component in the Teams meeting invite. After talking with MSFT the common thread was that those with issues were not showing as a user type of 'Member' in Entra ID, when their account was updated to be a 'member' their problem went away.

I am now seeing that even with the entire org being user type 'member' I am still getting this - I have a meeting with 17 people, 15 were auto added and 2 were not (everyone on the invite list is a User Type 'Member').

Is anyone else experiencing this? Any advice / ideas welcome on how to ensure that when you add notes/agenda's to a meeting that everyone on the invite list gets included and added by default.

Thanks in advance! 😀
