If you have the Hybrid Calendar and you've used @meet or @webex (or @spark) or included a video address in your meeting invitation, the service automatically updates the invitation with multiple ways to join the meeting. If you update the meeting later, the service does not automatically delete or overwrite the details for you. Follow these steps to update the meeting.
1

Go to your work calendar app and edit the meeting invitation.

2

In the body of the invitation, delete all the existing join details.

3

Change the meeting location or video address. (For example, change @meet to @webex.)

4

Send the updated invitation again.
