Configuring Efflux Migrator with Non-Administrator Credentials

Question: While configuring the Efflux Migrator, do I need to use domain\admin credentials for the Source Exchange Server configuration, or can I use a non-administrator account? ( Instructions in this knowledge base article applies to: Efflux Migrator – On-Premises Exchange Migration)


Answer By default, it is common practice to use domain\admin credentials when configuring the Source Exchange Server in Efflux Migrator. However, if there is a requirement for using non-Domain administrator credentials, Efflux Migrator can also be configured using a standard domain user account, provided that user has the required permissions.

The domain user account in the Source Exchange Active Directory must be a member of the following groups only:

  • Organization Management

  • Recipient Management

For further reference on Exchange permissions required for mailbox migration, refer to Microsoft’s official documentation:
