I have deleted a calendar invite by accident, I am the sender

Hello Thomas Hawkins

Based on the details you shared, I understand how frustrating this situation can be, especially since you were the original organizer and are now trying to restore and resend the same meeting invitation to all participants.

From my experience and after testing this scenario in my own environment, you may try restoring the meeting via Outlook on the web. Please navigate to Deleted Items, locate the deleted meeting, right‑click on it, and select Restore. After restoring, kindly check whether the meeting reappears on your calendar and if it is successfully reinstated.

I hope this helps.

If the meeting is still on your calendar (for example, only the invitation email was deleted), open the meeting on your calendar, make any needed changes, and select Send Update to resend it to attendees.

If the calendar event itself was deleted and you were the organizer, create and send a new meeting request:

1. In Outlook, open your Calendar.
2. Choose New Meeting (or New event, depending on your Outlook version).
3. Add the Title, Location, Start/End time, and any message details.
4. In To/Attendees, add the people who should receive the invite.
5. (Optional) Make it recurring if needed by using the Repeat options.
6. Select Send to send the new invitation.

If using Outlook on the web, the same can be done by selecting New event, filling in the details and attendees, then choosing Send.
