Why am I not seeing participants in my teams meeting options to add as a co-organizer?

Hi Didi,

The individual that I would like to add as a co-organizer was added a required attendee. The issue seems to be tied to if the individual is added during he initial meeting invite creation or if after in edit mode. If added initially, they will show as participants available to add as co-organizers. Individuals who are added as required attendees after an invite is created, so through editing, are not available in the drop-down or through search to be added as co-organizers. To me it seems to be something in the versioning of the meeting.

Do you (or anybody else) know how Microsoft handles meeting invite versions? It seems like it is a create duplicate and delete old since outdated versions of the meeting invite always get moved to my deleted folder in Outlook. I am curious if this is has something to do with it, and if Teams meetings don't recognize new versions that same way as they do with the original.

Thanks,

CJ

Hi Steven,

I was able to get a technical ticket on this issue opened and provided the engineering team with some log files. I haven't followed up with it, as my specific incident eventually resolved.

I have encountered it again when I've forgotten to add somebody or we have a new team member hired that needs to be made a co-organizer. It does seem like there is a delay in their servers in processing additional attendees added after the initial invitation creation, but I've eventually seen it resolve if I wait long enough/if I have the time to wait.

Hopefully there are still working on a real fix.

Update: I've tried to replicate the issue. The error seems to be tied to when required attendees are added to the invite. For example, I created a new invite and added a required attendee and then sent out. She was available for selection. I then went to edit and added a second required attendee. He was not available to select in co-organizer, so the same issue as my initial post.

Hi @Ahmed-Masoud97,

Thank your for these suggestions. I've tried all of these steps and the issue is occurring. This isn't the first time I've experienced the issue, but it seems to be sporadic and often related to items coming from a group or channel calendar instead of when a Teams meeting is added to an invite being sent from outlook.

Hi CJ,

I'm Ahmed and I am here & happy to help.

It's a weird issue!

Please check the following steps:

• Clear Teams Caches:

2. Cut and paste %appdata%\Microsoft\Teams into File Explorer.
3. Delete the contents of the entire folder.
4. Restart Microsoft Teams.

If you're using Mac, try clearing the Teams app cache this way.

1. Sign out of Microsoft Teams
2. In the Finder on the Mac, choose Go > Go To Folder. Enter the path to the following folders and delete the files they contain:

~/Library/Application Support/Microsoft/Teams/Application Cache/Cache

~/Library/Application Support/Microsoft/Teams/blob_storage

~/Library/Application Support/Microsoft/Teams/Cache

~/Library/Application Support/Microsoft/Teams/databases

~/Library/Application Support/Microsoft/Teams/GPUCache

~/Library/Application Support/Microsoft/Teams/IndexedDB

~/Library/Application Support/Microsoft/Teams/Local Storage

~/Library/Application Support/Microsoft/Teams/tmp

3. Restart Microsoft Teams

I hope this helps! Let me know if you have any further questions or concerns.

Best regards,
