Hi @J-3804
Welcome to post our Q&A forum!
You can try using the Exchange Online PowerShell to remove the meeting series. You can use the Remove-CalendarEvents
cmdlet to cancel future meetings in a specified mailbo, such as:
Remove-CalendarEvents -Identity "<MailboxIdentity>" -SeriesId "<SeriesId>"
Replace <SeriesId>
with the ID of the meeting series you want to remove. You can find the SeriesId
by opening the meeting series in Outlook on the web, clicking on the “Cancel Series” button, and then copying the SeriesId
from the URL in the address bar.
Hope it can help!
