How to hide invitation list in teams meetings?

In Microsoft Teams, when you enable the Hide Attendee Names feature, it prevents attendees from seeing each other's names during the meeting. However, if someone forwards the meeting invite, the full list of attendees can be revealed to the new recipient. This behavior occurs because the forwarding action sends the original invitation, which includes the attendee list.

To ensure that attendee contact details remain hidden, consider the following options:

1. Do not allow forwarding: When setting up the meeting, you can disable the option to forward the invite. This can be done by the meeting organizer in the meeting options.
2. Use a distribution list: Instead of inviting individuals directly, consider using a distribution list. This way, only the name of the distribution list will be visible to the attendees, rather than individual names.
3. Communicate with attendees: Inform attendees not to forward the invite if confidentiality is a concern.

Unfortunately, there is no built-in feature in Teams that completely prevents the visibility of attendee names when an invite is forwarded. The option to hide attendee names primarily applies to the meeting interface rather than the invitation email itself.

Dear @Caro B, 

Thank you for posting your question in the Microsoft Q&A forum.   

I’ve experienced a similar situation. The “Hide attendee names” option protects privacy during the meeting. It does not change how Outlook/Exchange stores the meeting object (where the recipient list is needed to track responses, scheduling conflicts, etc.). So, when someone forwards the invite, they forward the original meeting object, including all the people you added. 

“Names of people invited won’t be hidden in the meeting details.” In other words, the Outlook/Teams calendar item still contains the full list of invitees. 

So in this case, you can try these steps: 

• Create the meeting just for yourself (don’t add attendees)  
• Turn off Allow forwarding 
• Enable Hide attendee names 
• Send the join link and use BCC for recipients 
• This way, there’s no recipient list in the meeting object, so forwarding won’t reveal anyone else. 

However, as the article says, “Names of people invited won’t be hidden in the meeting details,” so they will still appear in the meeting details.

This is an interesting point you discovered, and it made me pay attention to it as well. In this case, I suggest you raise feedback on the Microsoft Feedback Portal Ideas · Community. The Product Team manages that site and constantly reviews customer comments and feedback. Many features have been developed or improved based on user suggestions. 

Looking forward to your response!
