  • Cross-tenant synchronization
  • Unsupported synchronization scenarios
  • Updating exchange attributes such as proxyAddresses and HiddenFromAddressListEnabled

    Cross-tenant synchronization can manage user properties in Entra. It does not directly manage exchange attributes. For example:

  • SMS sign-in enabled users are skipped

    An external user from the source (home) tenant can't be provisioned into another tenant. Internal guest users from the source tenant can't be provisioned into another tenant. Only internal member users from the source tenant can be provisioned into the target tenant. For more information, seePropert

    Configuring synchronization from the target tenant isn't supported. All configurations must be done in the source tenant. The target administrator is able to turn off cross-tenant synchronization at any time.

Ensure that the mail attribute is not shared among users in the source tenant. In addition, please ensure that t
