Organizing, editing, and coordinating meetings and events within Microsoft Teams calendars
Hi @LanceAblin-8705,
If you're the meeting organizer, you can usually change the time of a recurring channel meeting by opening Teams > Calendar, selecting the meeting, and choosing Edit. Teams should give you the option to edit either a single occurrence or the entire series, depending on what you want to change.
Alternatively, you can open the meeting details and use the available options displayed there to edit.
Change the meeting time, then select Save. In the new Teams calendar, you may see Save instead of Send update; saving the meeting applies the change and updates the attendees.
Note: The meeting organizer typically needs to make this change. If the option is not available, you may not have the required permissions or may not be the original meeting organizer.
I hope this information is helpful to you.
