Best practices: Open OneDrive/SharePoint sharing but restrict Teams guest access by domain

Hi ​ VasilMichev​,

The challenge is that using Teams External Access domain restrictions would also restrict our federated Teams chat and meeting scenarios, which we would like to keep open for all external domains.

Our goal is specifically:

• Allow OneDrive and SharePoint sharing with external users from any domain
• Allow Teams external chat and meetings with users from any domain
• Restrict only Microsoft Entra B2B guest accounts that can be added to Teams to a defined list of approved domains

As far as I understand, Teams External Access policies would impact both chat and meeting federation, not just guest access.

Have you seen a way to restrict Entra B2B guests used for Teams guest access while keeping external chat, meetings, and OneDrive/SharePoint sharing open for all domains?

Thanks!
