Teams user shows up twice in the same meeting

Hello Teams Community,


Please I need your help on this.

One of our MS Teams users has a problem where the account shows up twice in a meeting. 1 normal account and 1 guest user at the same time.

The user is only seen as a guest user when calling from the mobile version of the Teams app.

When using the Desktop Teams app this problem does not occur.


Could you please help?

Hi @66304432,

Does this only affect the particular user and can be reproduced in all meetings the user is invited in?
Is the user an internal user in your organization?

Please make sure the user is attending the meeting from only one device. Besides, by "calling from the mobile version of the Teams app", do you mean the meeting was joined by dialing the phone number included in the meeting details? If this is the case, it's suggested to try directly joining online from within the Teams app and check the result.

Thank you for your reply. I will answer your questions:

  1. It only affects this user and can indeed be reproduced in all meetings that this user joins, including meetings created by the user.



  2. This is an internal user for our organization and also does not have a guest account of any sorts in our domain.


  3. it happens with any regular Teams meeting, no channels.


When user only joins from Mobile, the user is seen as guest and has to wait in the lobby until someone lets the user in.

The user only uses the same Teams / Microsoft account on both devices. There is no Teams channel involved and the user does not have a guest account, I checked this.



The user only joins the meeting from the mobile device, using the Teams Calendar. No Number dialing.

I would also like to add that this user had no problems until the user had gotten a new Mobile phone. With the Teams app on the new Mobile phone this problem started occurring.

On this phone I also tried removing the account, clearing the Teams app cache and clearing the app data, as well as reinstalling the Teams app entirely but it did not help.

Looking forward to your response.

Hi @66304432,

Can you try testing by adding this user's account to another normal user's Teams app on mobile phone and see if the issue can be reproduced?
Or you can try logging in on this new mobile phone with a user's account which hasn't met this issue and check how it goes. This helps further confirm whether the issue only affects the particular device.
