Shared channel not adding external users (One way issue)
Hello everyone, Hope someone can provide insight to this, i've been trying to find solution for the past few days to no avail. Background: Create shared channel between 2 organizations (My organization and the opposite organization) Both organizations have set up all B2B Direct connect inbound/outbound settings in cross-tenant access settings (Azure AD) Both organizations have ensured teams settings and shared channels are enabled. (Teams admin control centre) My organization is able to add the opposite organization into the teams channel as guest (in standard channel) Issue: The opposite organization is able to add me into their shared channel without any issue. When i try to add the member of the opposite organization, the following message popped up Solutions attempted: Adding the member from the Microsoft Teams admin control centre. Checked and confirmed that settings under admin.microsoft.com > settings > org settings > services | Microsoft Teams & Microsoft 365 Groups are identical for both organizations. Deleted the guest user and re-created again in admin.microsoft.com > users > Guest users > add new guest users via invitation (AzureAD) which led to the above screen cap scenario B2B collaboration and B2B direct connect in azure AD cross-tenant access settings all set up properly and identical for both organizations References: https://learn.microsoft.com/en-US/microsoft-365/solutions/collaborate-teams-direct-connect?WT.mc_id=TeamsAdminCenterCSH&view=o365-worldwide https://learn.microsoft.com/en-us/MicrosoftTeams/shared-channels#shared-channel-limits https://learn.microsoft.com/en-us/microsoftteams/shared-channels-errors https://learn.microsoft.com/en-us/microsoftteams/teams-policies https://learn.microsoft.com/en-us/azure/active-directory/external-identities/cross-tenant-access-settings-b2b-direct-connect
