Organizing, editing, and coordinating meetings and events within Microsoft Teams calendars
Hi Roxane,
Thank you for reaching out.
To narrow down what is preventing the changes, please share the following information:
- Did you originally create these meetings, or were they created by someone else?
- Do you receive an error when editing or deleting them? If so, please share a screenshot of the error message.
- Are these individual meetings or part of a recurring meeting series?
- Does the same issue occur in both the Teams desktop app and Teams on the web?
In the mean time, please try the following workaround if you created the affected meetings:
- Sign in to Outlook on the web using the same account used in Teams.
- Open Calendar and locate the affected meeting.
- Open the meeting and edit or select Cancel.
- If it is recurring, choose whether to update or cancel only that occurrence or the entire series.
Thank you again for your time and patience. Looking forward to your response.
