  • Those are mine and the alter ego is from this account and not the government side. So the two user agent’s where setup by me.

  • Follow these steps to configure customized settings for specific organizations.
    Sign in to the Azure portal using a Global administrator or Security administrator account. ...
    Select External Identities, and then select Cross-tenant access settings.
    Select Organizational settings.
    Select Add organization.

  • Yes, cross-tenant authentication for Exchange Online can be used to give users from one tenant access to Exchange Online resources in another tenant. This can be done by configuring a trust between the two tenants, which allows users from one tenant to be authenticated by the other tenant's Active Directory. Once the trust is established, you can then use Exchange Online remote sharing features to give users from one tenant access to the other tenant's Exchange resources, such as mailboxes and calendar items.
