Unable to add an internal TEAMS member to a shared channel

Hello everyone,

I have a problem adding a user to a shared channel.

I am the owner of the channel, the user is an internal user of the community.

For all users everything goes well but this user is systematically rejected. I waited to see if it was a one-time problem but the problem noted last week is still present. This user is denied on all shared channels and accepted on private channels.

teams

I checked the user's configuration, his licenses, everything is the same as other users, I checked his Teams policies, he has the default policies.

I don't know where to look, do you have an idea or a link to Microsoft support so that they can intervene?

Thank you,

Best regards.

    Hi @Lionel PERES

    Would it be possible that the user had something changed recently?

    For example, his alias or UPN was changed.

    And since we cannot get useful information from the error message, I would suggest using Teams Powershell to see if it can work as a workaround.

    If not, if it would return more detailed information.

    You can use the following cmdlet:

    Connect-MicrosoftTeams
    
    Add-TeamChannelUser -GroupID (Get-Team -DisplayName "Team name here").GroupID -DisplayName "Shared Channel name" -User "user@domain.com"
    

    If still no luck, please consider contacting support via opening a new service request in Microsoft 365 admin center>Support>New service request to have them look deeper into this issue.

    I execute the command, here is the return:

    57f44a3a-766f-4c29-84b5-34bca0768a21

    It therefore seems that this user is a former "guest" who has been converted into an internal member.

    This is already an explanation. Should we delete this user and recreate him as an internal member directly or would it be possible to convert him well so that he is accepted in the shared channels?

    Thanks for your help.

    it's strange the user is indeed a "type: Member" it is not a guest.
