Migrate Exchange mailboxes with Admin account

Exchange servers allow the use of an admin account to migrate mailboxes without knowing the passwords of each user. Please notice the following advices for migrations with admin account:

  1. The admin account can be a standard user with full access rights on the mailboxes, which should be migrated. A guide to add mailbox permissions can be found here: Read and add mailbox permissions on Exchange servers

  2. If muliple mailbox migrations are run in parallel, throttling limits must be deactivated for the admin account: Disable EWS Throttling for Exchange 2010 users or Disable EWS Throttling for Exchange 2013 users.

Hint: A standard user with full access on the mailboxes can be used within our service. A domain admin account is not required.
