Recurring meeting disappeared from my calendar (Host) but appears on attendees calendar

Question

A recurring meeting invite that repeats once a week is no longer appearing in my calendar, but on all of the attendees' calendars. I want to cancel this recurring call, however, when I scrolled to Feb 11th (a Wednesday that should show this same invite), it showed a completely different invite that I never sent that is referencing the same ZOOM invite. I then deleted this second attachment to see if it would delete the recurring email from all attendees’ Outlook calendar, and that did not fix the issue. I’ve also deleted the Feb 11th ZOOM meeting from my ZOOM portal and nothing worked.

 Please note that the calendar meeting is not showing up on my mobile or web portal either.

In addition, I’ve asked my colleague to forward me the meeting invite to see if this would bring it back onto my calendar, but it keeps giving me the same error message shown in the third attachment: “We couldn’t find this meeting in the calendar. It may have been moved or deleted.” I’ve also tried forwarding the initial invite back to myself and it keeps giving me same message. Could you please advise on how to cancel this invite?

Hi @Lizzy Tiano, 

Welcome to the Microsoft Q&A forum. 

Thank you for the thorough checks you already performed across classic Outlook, Outlook on the web and mobile, as well as your efforts with the Zoom entry and forwarded invites. Based on the details you shared that the weekly recurring meeting has disappeared from your organizer calendar while it still shows for attendees, and you need to cancel the series. 

This behavior typically occurs when the series master was removed or became inaccessible in the organizer mailbox, so Outlook cannot locate the item to send a proper series cancellation. Microsoft has documented scenarios where meetings show on attendee calendars but are missing for the organizer and provides workarounds to regain control. Also, only the original organizer copy can issue a cancellation, which is why forwards report that the meeting cannot be found.  

To address this, please follow the steps below that suit for your situation: 

1/ Try to restore the series master, then send a series‑level cancellation 

• In classic Outlook, open Deleted Items and search for the meeting subject. If you do not see it, use Recover items deleted from this folder to restore from the Recoverable Items folder. 
• Once the series is back on your calendar, open the series and send a cancellation to remove it from attendee calendars. The same recovery options exist in Outlook on the web. Cancel a meeting - Microsoft Support 
• Go to Deleted Items and search by the meeting subject. If found, move it back to Calendar, open the series, choose Cancel, and send the cancellation. 
• If it is not in Deleted Items, choose Recover items deleted from this folder, restore the series item, then open it from your Calendar and send the series cancellation.  

2/ If recovery is not possible, ask your Microsoft 365 admin to run an organizer‑side cleanup 

• Your admin can use the Exchange Online cmdlet named Remove‑CalendarEvents to cancel future instances that you organized within a chosen date range.  
• This action sends cancellations to all attendees even when the organizer’s local copy is missing. Share the meeting subject, your mailbox address, and the date window to target.  
• Reference: Remove-CalendarEvents (ExchangePowerShell) | Microsoft Learn 

3/ Repair access to the item and use Microsoft’s documented workaround for older affected meetings 

• Use the Microsoft documented ICS workaround to regain control and generate a cancellation when the organizer copy is missing for older series. The article explains how to obtain the series as an ICS and complete the cancellation from your side. 
• Start Outlook in Safe Mode and temporarily turn off the Zoom add‑in, then retry opening or canceling the series. This rules out an add‑in conflict. 
• If you still cannot access the item, create a fresh Outlook profile to rebuild your local calendar state and, if needed, recreate the offline data file. Then check the calendar again.

4/ Contact IT administrator:   

Since your account is managed by your organization, please contact your IT administrator to review your permissions and policies. If the issue persists after these checks, ask your IT administrator to submit a support request directly to Microsoft Support team.
