Provide credentials to access the production environment of an organization that contains data to which you want to compare your current backup state.
Depending on the organization type, the first step of the credentials dialog will be different:
When comparing with on-premises Exchange organizations, specify the Global Catalog server name and valid access credentials. For more information on required permissions, see Required Permissions.
When comparing with Exchange Online organizations, specify the account to connect to the target Exchange server. You can use your current account or provide another one in the <username>@<organization>.onmicrosoft.com format.
