We have external sharing enabled for Teams an Invitation of external guest is allowed for members and group owners, all setup according to this article:

https://learn.microsoft.com/en-US/microsoft-365/solutions/collaborate-as-team?WT.mc_id=TeamsAdminCenterCSH&view=o365-worldwide

But an group owner is not able to invite external guest, the dialog just say, "unable to find the email address".

Any idea?

    There's a bunch of other settings that need to be enabled for this to work, as detailed in the article above. For starters, check the "members can invite" one in Azure AD, it controls whether regular users in the tenant ("members", as in not admins) can invite others.

    Hi @Yiru Chen

    Except for these settings above in this article, please make sure you have added a valid guest user account in Teams client.

    Moreover, we also recommend you contact with invited guest user and ensure if they have blocked your domain.

    If the above suggestions are not work for you, we have some questions to confirm with you:

    1.Does anyone else have the same issue in your organization?

    2.Have you tried to add the guest user in Teams web client?
