Exchange 2019 – Email Address Policy per User

androidemail-serverexchangeexchange-2019outlook

We have been tasked with changing our company domain for email. Active Directory will remain the same. I have created (but not applied) a new Email Address Policy that specifies the new domain. The only other Email Address Policy is the default with our original domain.

When we migrate, I need to be able to apply it to users one-at-time, to assist them with updating their devices. Google is failing me. Does anyone out there have experience / tips on this process?

Best Answer

  • Create the new policy and don't apply it, as you already did.
  • Turn off policy-based address management for all mailboxes:

    Get-Mailbox | Set-Mailbox -EmailAddressPolicyEnabled $False

  • When you want to apply the new policy to a mailbox, turn it on again:

    Set-Mailbox -Identity [email protected] -EmailAddressPolicyEnabled $True
