Prerequisites for the Exchange Mailbox User Mailbox Hybrid Environment

Before you set up Exchange Mailbox in the Command Center, you must perform the prerequisite tasks.

Assigning Permissions to On-Premises Service Accounts

Assigning Permissions to Online Service Accounts

If you are using basic authentication, you must perform the following prerequisite tasks:

Note:

  • Azure tenants with default security enabled are not supported as the default security setting does not permit configuration of MFA App password for service accounts.

If you are using modern authentication, you must perform the following prerequisite tasks:

  • Register the Application
  • When you upgrade to Feature Release 20, if you move from basic authentication to modern authentication and you are using a manually created app, you must have the Group.Write.All permission under Microsoft Graph and the full_access_as_app permission under Under Supported Legacy API in the Azure portal.
  • When you upgrade to Feature Release 20, if you move from basic authentication to modern authentication and you are using an automatically created app, select Authorized App under Connection in the Exchange Settings page so that the required permissions are added automatically.

Note:

  • Modern authentication requires only one service account. The service account can be an unlicensed Exchange admin user.
  • Azure tenants with default security enabled are not supported as the default security setting does not permit configuration of MFA App password for service accounts.
  • If you choose Express Configuration, by providing global admin credentials, Azure apps and unlicensed Exchange admin user is auto created.
