Using New Outlook on Windows for professional communication and productivity
Dear @Henry Lee,
Good day. Thank you for posting your question in the Microsoft Q&A forum!
I sincerely apologize for the inconvenience you’ve experienced. I truly appreciate your patience during this time and thank you for bearing with us. Based on your description, I understand that you're running into an issue with new members not seeing past events in the group calendar.
In this case, please kindly allow me to provide some information:
There’s no automatic back‑invite for events that existed before someone joined the group. New members get permissions to the shared resources (including the group calendar) when they’re added to the group, but they aren’t retroactively added as attendees to past or already‑scheduled meetings. You’ll need to update the meetings (manually or with automation) so they receive invitations, and the events appear on their personal calendars
For reference:
