HiI am trying to change the default accepted domain in Exchange 2010In the EMC, under "Hub Transport", "Accepted Domains"When I try to set an Accepted domain as the default I receive this error: "Email address policy opject doesn't have a primary SMTP E-Mail address specified in the template"I think that this is because the Default email address policy is not configured correctly.When I go to the "E-Mail Address Policies" tab I receive this warning:--------------------------------------------------------Microsoft Exchange Warning--------------------------------------------------------Warnings Get-EmailAddressPolicyCompleted Warning:The object Default Policy has been corrupted, and it's in an inconsistent state. The following validation errors happened: Warning:The e-mail address policy object doesn't have a primary SMTP E-mail address specified in the template.--------------------------------------------------------When I try to edit the Default policy I find that there are no SMTP addresses conifgured, so I add: %m@example.comBut this operation always fails on the completion step:--------------------------------------------------------------------------------------Summary: 1 item(s). 0 succeeded, 1 failed.Elapsed time: 00:00:03 Edit Default PolicyFailed Error:The operation can't be performed on the default e-mail address policy.

I have managed to set the primary SMTP address in the default policy.On the Domain Controller I ran: adsiedit.mscConfiguration [dc.example.com] CN=Configuration,DC=example,DC=com CN=Services CN=Microsoft Exchange CN=Example Company CN=Recipient Policies CN=Default Policy gatewayProxy: SMTP:%m@example.comI can now change the default accepted domain.

Did you make the change in ADSIEDIT, delete it or ?

Or better - use powershell: Get-EmailAddressPolicy def* | Set-EmailAddressPolicy -EnabledEmailAddressTemplates 'SMTP:@New.Domain'
