Question

Creating webinar in Teams Desktop app creating two events in calendar

MegD 0

When creating Teams webinars via the Desktop app it seems that two events get created and added to the calendar. When I make a webinars with the same settings via the browser, there is only one event. Is this a glitch or do these two events have different purposes?

Thank you

Hello,

Thank you for the response. In both cases, I am the organizer and not signed up as an attendee.

Hi @MegD,

Thank you for the quick clarification. I understood that in both cases you’re the organizer and didn’t sign up as an attendee.

When this happens without attendee sign‑up, it’s typically one of the two scenarios below. The quickest way to tell which one you’re hitting is to compare the Join links of the two entries:

1/ Two different meetings were created

This can occur if a new Outlook meeting was created (or an event was duplicated) and the webinar join link was pasted into it, or if the Outlook “Teams meeting” toggle generated a separate meeting behind the scenes. To verify, please open each calendar entry and copy the Join link/Meeting ID.

If they’re different > they are two separate rooms.

Keep the original webinar (the one created in Teams), cancel the extra Outlook meeting, and share the registration link or invite presenters directly from the webinar object going forward.

2/ One meeting shown twice

If the two entries have the same Join link, it’s usually a duplicate calendar item (e.g., added by a delegate, a .ics added by a client, or a cache/sync artifact). Please delete the duplicate entry, then sign out of Teams and clear the client cache (or try Teams on the web) to ensure it doesn’t reappear.

3/ Contact Support

If the behavior still continues, please contact your organization’s IT support team so they can help verify your Outlook–Teams sync, calendar permissions, and invite workflow on your tenant.

In case your IT department cannot access the necessary information or make the required changes, I recommend asking them to open a request with Microsoft Support team through the Microsoft Admin Center. They have access to backend configurations and can perform a more in-depth investigation. At the very least, they can provide the most effective workaround to ensure your experience remains smooth and secure.  

We kindly ask for your understanding that, as moderators, we do not have access to the administrative tools or permissions required to investigate or modify these configurations. We also do not have the capability to initiate remote sessions for direct assistance. Our role is to guide users to the appropriate resources and support channels.

I hope this helps. If there’s anything else you’d like me to check or clarify, please feel free to reach out.

Answer 1

Hi @MegD,

Thank you very much for sharing your experience regarding seeing two calendar events after creating a Teams webinar in the desktop app. I appreciate your patience and for the screenshot you provided.

1/ Why you may see two calendar entries for the same Teams webinar

This typically isn’t a glitch. In most cases, the second entry appears when the organizer (or someone on the team) also adds the webinar to the calendar as an attendee from the registration confirmation email (“Add to calendar”). In Teams, saving a webinar creates the organizer/presenter meeting (and the invite for co‑organizers/presenters), while attendees receive a registration email with an .ics to add to their calendars. If the organizer registers as an attendee to test the flow, you’ll see both items on the organizer’s calendar.

This is also why you may notice two items after using the desktop app (if you tested the registration there) but only one when scheduling in the browser (if you didn’t add it via the attendee confirmation).

Note: Two separate Teams meetings can unintentionally be created if a new Outlook meeting is made and the webinar join link is pasted into it Outlook generates a different meeting link/ID, which can split attendees between two rooms. To avoid this, please share the registration link or invite people directly from the original webinar object instead of creating a brand‑new Outlook invite.

2/ Best practices for the future

Please:

Keep the organizer/presenter webinar entry and remove any extra attendee‑style calendar item that came from “Add to calendar.”
Share the registration page with attendees (or add them in the webinar) rather than creating a separate Outlook meeting and pasting the join link.
If duplicates still appear without using “Add to calendar,” please update Teams/Outlook and clear the Teams cache, or try scheduling from Teams on the web to compare, these steps resolve most calendar duplication/plugin issues.
