Exchange 2010 SP1 Multi Tenant and Recipient Validation RRS feed

  • Question

  • Hi there,

    We are running a multi tenant exchange 2010 sp1 installation. We have configured the setup to perform recipient validation by running

    Set-RecipientFilterConfig -RecipientValidationEnabled $true

    However, now all email is rejected with

    550 5.1.1 User unknown

    Yes, even for valid email addresses.

    Any help is appreciated,

    Regards

    Leon
