Can't remove external presenter in Microsoft Teams Webinar

Hello,

I am trying to remove some external presenters from my Microsoft Teams webinar, but clicking the 'X' button - which normally works - is not removing them.

It is likely worth noting that these external presenters who can't be removed are in fact, for some reason, duplicates. In other words, there are three real presenters here but they are each entered twice. There were two other external presenters that I was able to remove, and they did not have duplicate entries. I'm not sure if this has something to do with it.

I have tried this on both the desktop client and the web app. Please let me know how this can be solved.

Many thanks,

  • hi cs02​  This sounds like a sync/UI issue rather than something you're doing wrong, especially since the duplicated external presenters are the ones that cannot be removed.

    A few things worth trying:

    • Open the webinar from Teams calendar -> Edit event instead of the webinar management page
    • Remove the presenters there and save again
    • Try updating the webinar from Outlook on the web as well
    • Clear Teams cache or try an InPrivate/incognito browser session

    Sometimes duplicate external attendees/presenters get "stuck" due to backend sync issues between Teams and the calendar object.

    If none of that works, the fastest workaround is often:

    • Create a new webinar
    • Re-add the correct presenters manually

    Unfortunately, duplicated presenter entries in Teams webinars are a known type of issue people occasionally run into.
