Meeting series disappeared in organizers calender

Microsoft

Hi,

 

This is Sean from Geneva Actions team, and I am writing to ask help for an issue with my calendar. A meeting series are disappeared from my calendar and I am the organizer of this meeting series. Is there a way to get it back rather than create a new series? I don't want to deprecate it because our team has many valuable discussions in that channel. Could you give me some suggestions/instructions on how to fix it?

 

Thank you very much!

Sean

Here are some general troubleshooting steps you can try:

  1. Refresh your calendar: Sometimes, the disappearance of a meeting series can be due to a temporary synchronization issue. Try refreshing your calendar by closing and reopening it or by syncing it manually to see if the series reappears.
  2. Check your deleted items: It's possible that the meeting series was accidentally deleted. Look for the meeting series in your deleted items or trash folder. If you find it there, you can restore it to your calendar.
  3. Search for the meeting series: Use the search functionality in your calendar application to look for the specific meeting series. Enter relevant keywords or the names of participants to narrow down the search. It's possible that the meeting series got moved to a different location within your calendar.
  4. Check other devices and platforms: If you access your calendar from multiple devices or platforms, such as a smartphone, tablet, or web browser, verify if the meeting series is visible on any of these other platforms. It's possible that it's still present on one of them.
  5. Contact your IT support: If you're using an organization-wide calendar system, such as Microsoft Outlook within an enterprise, reach out to your IT support team. They may be able to assist you in recovering the missing meeting series or provide further guidance.
  6. Restore from a backup: If you or your organization regularly back up your calendars, there may be a chance to restore the missing meeting series from a backup. Consult your IT support or system administrator for assistance with this process.

Remember to inform your team members about the issue, so they are aware of the potential loss and can help in finding a solution. Additionally, consider creating a new meeting series or scheduling individual meetings to ensure that your team's discussions can continue even if the original series cannot be recovered.

These are not really addressing the problem. It is a recurring problem, where the meeting the organizer has created is missing only from organizer's meeting. The metting is not deleted, it is still active in participants' calendars, and room resources locked. And the invite in sent folder, but impossible for organizer to accept to get it into calender, since he/she is the organizer. There does seem to be a "bug" somewhere. The meting is gone on all devices and types of devices. So seems like an Exhchange bug.

 

Totally agree with @Morten_HP . I have the same issue and meeting is not visible in my calendar but it is in all attendee's calendar. I cannot edit or delete it and I cannot see it on any platform. It is an reoccurring meeting so it is really annoying I cannot just delete and rebook it. Please help!

If the issue persists despite the general troubleshooting steps, and the meeting series is consistently missing from the organizer's calendar but visible in participants' calendars, there could indeed be an issue that requires more advanced investigation. Here are additional steps you might consider:

  1. Outlook Web App (OWA):
    • Log in to the Outlook Web App (OWA) using a web browser.
    • Check if the missing meeting series is visible in OWA. Sometimes, issues can be specific to the Outlook desktop client, and OWA provides an alternative view.
  2. Cached Mode:
    • If you are using Outlook in Cached Exchange Mode, try turning it off temporarily and see if the meeting series reappears.
    • To disable Cached Exchange Mode, go to File > Account Settings > Account Settings. Select your Exchange account and click "Change." Uncheck the box for "Use Cached Exchange Mode."
  3. Recreate Outlook Profile:
    • Consider recreating the Outlook profile. This involves removing the existing profile and setting up a new one. Make sure you have necessary account information before doing this.
  4. IT Support Assistance:
    • Reach out to your IT support team again, providing them with detailed information about the issue.
    • If possible, ask them to check the Exchange server logs for any errors or anomalies related to the missing meeting series.
  5. Exchange Server Investigation:
    • If you have access to Exchange Server logs or have an IT team that manages the Exchange Server, investigate if there are any logs or errors related to the missing meeting series at the server level.

 

It may also be possible that the problem you are experiencing is related to updates, either to the Outlook client or the underlying Exchange server. Software updates can sometimes introduce unexpected behavior or uncover existing bugs. Here are a few considerations:

  1. Check Release Notes:
    • Look into the release notes or update documentation for the version of Outlook you're using. Sometimes, updates include information about known issues or bug fixes.
  2. Temporary Glitch:
    • Occasionally, a specific update might cause a temporary glitch. If the issue appeared shortly after a recent update, it might be worthwhile to monitor for subsequent updates that may address the problem.
  3. Rollback or Update:
    • If the issue started after a recent update, and it's critical to your workflow, you might consider rolling back to a previous version (if feasible) or updating to the latest version (if available) to see if the problem persists.

Before making significant changes, always ensure that you have a backup of important data, and consider consulting with your IT department or professionals if applicable.

Remember, software can be complex, and interactions between different components (Outlook, Exchange, and updates) can sometimes lead to unexpected issues.

Please keep in mind that I am a simple user like you and my knowledge of the possible update errors that currently exist is very limited. The text with the steps was revised with the AI.

I, too, have this problem and i have tried even rebuilding my profile and nothing works.   I can't create a new meeting because I can't cancel  this meeting!  If i did, my attendees would have 2 meetings on their calendar so that would be confusing and just not an option.  I need a way to put my meeting back on my Outlook.  Each time participants re-forward it to me I can't accept it. It's like it's there on my calendar but not appearing to me.  *sigh*

@KBeatty I too had this issue & struggled for weeks trying to resolve.  I tried all solutions offered under this thread, to no avail.  I was finally able to resolve yesterday & wanted to share in case it helps someone else.  I viewed one of the other meeting participants calendar in Outlook, then went to the meeting. Double click the meeting & then it gives you the option to open the appointment.  Select "The entire series", then click OK.  From here it gives you the option to "Copy to My Calendar" under the Actions section. Click it and then click "Accept the meeting" to receive updates to the copied meeting. Now click OK. It should now be added back to your calendar with organizer permissions.  Hope this helps.                                                                                  

QuietStorm's workaround helped, but didn't exactly work. Copying meetings is unavailable to me. However, I did find a way to get the reoccurring meeting back in my calendar using part of their method. Once I got full access to a colleague's calendar, I selected the meeting from their calendar and forwarded it back to myself. Note that my colleague forwarding the meeting to me themselves did not work, I had to go into their calendar and forward to myself. Once the meeting showed up in my inbox, it magically appeared back in my calendar.

@Sean_Tong,

I had the same issue and I found a way to fix this problem. First I had someone forward the meeting to me, and then while I did not have the option to accept or decline as I was the organiser, I clicked the button to forward the invite and it just appeared in my calendar. (I didn't have to actually forward it to anyone). If someone is able to send you the meeting series, it's better as the past meetings and future meetings will appear too. I'm not sure how this work, but it did for me, so I hope you have some luck as well.

 

EDIT: I notice this solution makes you appear as an attendee and not the organiser rights to amend or cancel the meeting. It can be fixed by downloading the meeting as an iCalendar (ICS) file, opening it in Notepad (Right click and Open With, selecting Notepad, but don't check the box to always open it in Notepad), and removing your name from the Attendee list. It should still be in the Organiser field, as expected. Save and close the ICS file.

 

Then, instead of dragging it into Outlook which won't work (it'll open it as a meeting instead, which won't add it to the calendar), you instead have to go to File -> Open/Export -> Import and select the modified ICS file. It'll prompt you to open as a new calendar or use the existing one; choose existing, and it'll pop up in the calendar with you having the organiser rights.

I think it's to do with the fact that clicking Forward adds you to the attendee list despite also being the organiser so the organiser rights are lost when the event is put back in the calendar when you just press Forward.

Kind Regards
Sumble.

I have the same problem with the new version of Outlook, where meetings randomly disappear from the main Calendar window on my desktop, although they are still present on my mobile and tablets. Microsoft should correct this major bug quickly, as it is causing serious time management issues.
Encountered same issue and it's a recurring meeting for large group of ppl. I tried all the above and still did not work.

Even go to the meeting option setting to add "co-organizer", hoping that co-organizer may be able to cancel the meeting while it still does not work.

Really hope this can be fixed soon...

I agree with @Morten_HP. I experience exactly the same problem. I find my own meeting in my "sent" folder but not in the "deleted" folder. I also checked other devices as well as the web application, but without success. 

 

Additionally, I have asked two of the people who received the meeting to forward the meeting to me. I get it in my inbox, but it states that I'm not able to accept the meeting since I'm the organizer. 

 

Definitely a bug.

@QuietStorm78 

I ended up having my IT director roll back my Outlook to 4 days before the issue and was able to resolve that way.  But I've screen shot your solution for when it happens again.  This has happened now twice to me (both on the same meeting which has over 300 invitees) to it.

 

fyi

 

Thanks!

Seems like a burgeoning issue. Same thing happened to one of my meetings and there seems to be no remedy other than rolling back via IT. Half way through 2024, it would seem like this should not be an issue with a mature calendar tool like Outlook.

@Sumble23 This worked perfectly, thanks!

We have a large number of cases where meetings disappear from the atendee's calendar when they accept the meeting and organizer meetings disappear after they send the invitation.

Workaround is accepting the meeting from OWA. No clear solution to recover the organizer meeting, in some cases it helped to have one of the atendees forward the meeting back to the organizer.

This on top of the meeting conflict issue, it's a nightmare.

What update channel and build are you running?

We see some of the same issues in our enviroment.

We have a case open with M$ support.  We were able to do extensive logging and repeat the issue several times for them to have data and a lead to follow.  The Outlook team deemed it an Exchange Online issue.  The Exchange team hasn't responded yet.

 

Issue:  Organizer creates or modifies a meeting and sends it.  It gets deleted from the organizer's calendar (immediately), or sometimes from the attendee's calendar.

 

We have ruled out anything we can do with Outlook.  Update, rebuild OST, new Outlook profile, etc.

There is a way to put it back in the Calendar, but nothing to prevent it... SOOOO AGRIVATING!!! 

 

From MS:

Outlook debug team has analyzed the data collected from Ryan’s PC. Their analysis confirms my initial analysis of the data, we need to understand why the server is throwing this error on frame 922 when “Test13” gets created by Outlook.

Here is a PIA procedure to get the meeting back into the Organizers Calendar.  It is not a fix.

 

  1. Find the missing meeting from someone internal. It doesn’t have to be the Organizer, but if it is, it hopefully is still in their Delete or Sent folder.
  2. Forward the meeting to yourself WITHOUT NOTIFICATIONS/ALERTS/UPDATES
  3. Tentatively accept the meeting, again WITHOUT NOTIFICATIONS/ALERTS/UPDATES
  4. Open Outlook and navigate to the Calendar view.
  5. Find the Meeting you want to export.
  6. Double-click the Meeting to open it.
  7. Go to the "File" Menu: In the meeting window, click on "File" in the top left corner.
  8. Save As: Choose "Save As" from the menu options.
  9. Select File Type: In the Save As dialog box, select "iCalendar Format (*.ics)" from the "Save as type" dropdown menu.
  10. Save the File: Choose the location where you want to save the ICS file, give it a name, and click "Save".
  11. Open the ICS file in notepad (or some Editor) so we can make a modification. Change the following text:
  12. Find and Replace - METHOD:REQUEST to METHOD:PUBLISH
  13. Save the modified ICS file.
  14. Copy/Transfer the file to the person missing the meeting.
  15. Double-click the ICS file on the user’s computer.
  16. Accept the Warning message if one appears.
  17. Close the appointment window WITHOUT Accepting or Tentative Response.
  18. Outlook will ask if you want to Save, say YES.
