Hi, I've updated my Default Policy to reflect additional email addresses which should be applied to the Users Mailboxes. With the EMC it was not possible to update the Default Policy. Therefore I've set the AddressTemplates via Powershell: set-EmailAddressPolicy -Identity 'Default Policy' -EnabledEmailAddressTemplates '%g.%s@domain.ext','%g.%s@domain2.ext','%g.%s@domain3.ext' Unfortunately this overides all Address-Templates which already existed in the Default Policy. So I've tried to recreate the X400 Connector and the "Microsoft Mail" Address. But when I run this command: set-EmailAddressPolicy -Identity 'Default Policy' -EnabledEmailAddressTemplates 'MS:ORGINT/ORGINT','X400:c=US;a= ;p=ORG;o=Exchange;','%g.%s@domain.ext','%g.%s@domain2.ext','%g.%s@domain3.ext' I'll get this error: The following error occurred during validation in agent 'Rus Agent': 'Failed to valid the proxy address template "MS:ORGINT/ORGINT". Additional information: Failed to find the address type object in Active Directory for address type "MS:AMD64".. ' + CategoryInfo : NotSpecified: (:) [Set-EmailAddressPolicy], ProvisioningValidationException + FullyQualifiedErrorId : 1001372F,Microsoft.Exchange.Management.SystemConfigurationTasks.SetEmailAddressPolicy Any idea why I can't readd the "Microsoft Mail" address? Many thanks in advance!

I've no tracked the problem down to this: http://technet.microsoft.com/en-us/library/bb217922(EXCHG.80).aspx I found out that the Address-Type "MS:AMD64" doesn't exist in the AD by opening ADSIEdit and goto: Configuration -> Sevices -> Microsoft Exchange -> [Organization] -> Addressing -> Address-Types The list contains: CN=CCMAIL:i386 CN=GWISE:AMD64 CN=GWISE:i386 CN=MS:i386 CN=NOTES:AMD64 CN=NOTES:i386 CN=SMTP:AMD64 CN=SMTP:i386 CN=X400:AMD64 CN=X400:i386 As you can see MS:AMD64 is missing. Is this intended or is this an issue?

Do you still have Microsoft Mail in your environment? If not, why do you want to add the address? -- Ed Crowley MVP "There are seldom good technological solutions to behavioral problems." .
