Team Webinar with Share Link creating 2 meetings

Dear @Loretta Walden-Gafcon,

Thank you for reaching out to the Microsoft Q&A Forum.

I understand you had an unexpected issue where your webinar resulted in two separate, simultaneous Teams meetings opening, splitting your attendees. From my research, when you created the webinar, a single, unique meeting ID was generated and embedded in the initial Outlook calendar item. The most common reason for this type of split is that a co-organizer or staff member tried to invite the 87 people by creating a brand new Outlook Calendar invitation and then manually pasting the Join Link from the original meeting into the new invitation's body.

When Outlook creates a new calendar event, it automatically generates a new, unique meeting link and ID for that new event. Even if the text of the old link is pasted into the body, the new calendar item's inherent, background link often takes precedence, essentially creating a second meeting room. This means the 87 people clicked the link from the new calendar event, which directed them to Meeting ID Y, while you and the co-organizers clicked the link from the original calendar event, which directed you to Meeting ID X.

To confirm this and provide you with a precise solution to prevent this issue from happening again, could you please provide the following details?

• Can you confirm the exact method used to invite the 87 external attendees?
• Did someone open the original calendar event and add the 87 emails to the "Required Attendees" field?
• Did someone create a brand-new Outlook calendar item and manually copy/paste the webinar link into it?
• Did someone forward the original Outlook calendar item or the email body to the 87 people?
• Could you or your co-organizers see two separate meetings listed in your Teams Calendar?
• Did any of the invited attendees see the webinar show up in their Teams calendar as a separate meeting, or did this confusion only happen via the Outlook calendar invitation and the link they clicked?

I hope this information helps clarify the situation. I look forward to your reply with the extra details so we can work together to find a definitive solution and prevent a recurrence of this incident. Please note that our initial response does not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution. Thank you for your patience and understanding. I'm looking forward to your reply.
