uncancelling a webex meeting

Because you have not selected Send, discard the cancellation draft without sending it, then reopen the calendar item and verify that it is still the original Webex meeting.

Recover the meeting safely

1. In the open cancellation window, do not select Send or Send cancellation.
2. Select Discard, or close the window and choose Close without saving/Discard changes if Outlook prompts you.
3. Refresh Outlook on the web and reopen the meeting from Calendar.
4. Confirm that it opens as a normal meeting—not a cancellation—and still contains:
   • The original attendees
   • The Webex joining link, meeting number, and dial-in details
   • The original date and time

Outlook on the web does not complete the documented cancellation workflow until you select Send on the cancellation form.^1^

If everything remains intact, no update is necessary. If you make a genuine change, send it only after confirming that the item is a normal meeting-edit form. Never select Send while Outlook identifies it as a cancellation or shows Send cancellation.

If discarding does not restore the normal meeting

Do not send anything from the cancellation form. There is no documented command that reliably converts a retained cancellation form back into the original Webex meeting.

• Preserve the meeting details or take screenshots.
• Contact your Microsoft 365 administrator or Microsoft Support before taking further action.
• If the Outlook event is intact but its Webex meeting or joining link was deleted, contact Webex support or create a replacement Webex meeting. Webex treats cancellation as a separate operation from updating a scheduled meeting.^2^

If the cancellation was already sent

A sent cancellation cannot generally be “uncancelled” to restore the same Outlook meeting object. Create a new Outlook event, add a new Webex meeting, invite the original attendees, and explain that it replaces the accidental cancellation. Outlook documents that sending the cancellation deletes the organizer’s meeting, including its agenda, notes, and attachments.^3^
