EWS Basic Authentication (Delegation)

To use Delegation to perform an administrator driven migration, follow these steps:

  1. Create an account (either an admin or user account) in Exchange or Microsoft 365 that will be used as the migration account. We’ll call this the “migration” account.

  2. In the Exchange Admin Center, edit the account of a user to be migrated.

  3. Click on the Mailbox Delegation tab.

  4. In the Full Access section, add the “migration” user account.

  5. Repeat for all user accounts being migrated, or alternatively select and edit multiple users at the same time (carefully).

  6. In Transend Migration Console, enter the “migration” account credentials on the Configuration Settings > Required page.
