I'm trying to add guests to a channel on Teams. I've confirmed from the admin suite that guests are allowed and no policies are prohibiting them as far as I can tell. When I go to the 'add member' option on the channel OR in the team at large, and type in an email address, the 'add' button remains greyed out. There is no option to 'add as guest'.

    Hello

    Is the guest user coming from a personal account holder?

    If so, please make sure your admin user specifically turned on External users with Teams accounts not managed by an organization can contact users in my organization checkbox.

    If you're unable to add guests to a channel in Microsoft Teams, there are a few things you should check:

    1. Guest Access Settings: Ensure that guest access is enabled for your organization. You can verify this in the Teams Admin Center under the Org-wide settings > Guest access section.
    2. External Collaboration Settings: Confirm that the external collaboration settings in Azure Active Directory allow for guest invitations. An admin needs to sign into the Azure portal and check the User settings under External collaboration settings to ensure that members can invite guests.
    3. Channel Owner Permissions: Make sure that you are listed as an owner of the channel. Only channel owners can add members, including guests.
    4. Correct Email Format: When adding guests, ensure that you are using the correct email format. If the email address does not match the guest's account in Azure AD, it may not allow you to add them.
    5. Check for Policies: Even if guests are allowed, there may be specific policies or settings that restrict adding guests to certain channels. Review any policies that might be in place.

    If you've confirmed all of the above and are still facing issues, it may require further investigation by your IT department or Microsoft support.
