Hello there,
In Teams, channel meetings do not automatically grant co‑organizer status to channel owners or members; co‑organizers must be explicitly added to the meeting invite by name. When a channel member is also added individually, Teams creates two calendar entries (one from the channel and one personal), even though they both point to the same meeting series with the same chat, join link, Loop agenda, and recordings. This duplicate appearance is expected behavior and cannot currently be merged or eliminated. There is no supported workaround other than avoiding adding channel members unless co‑organizer rights are truly required; if they are added, the extra calendar entry can be hidden but not deleted without losing access to the meeting.
Thank you
