Dear All, we have acquired a new domain on internet and want some users (all in one main OU) to set there new aliases. e.g. if new domain is contoso.com I want all users to be able to receive the emails on firstname.lastname@contoso.com. Please note that users already exists in the exchange. For new users I can set in EMC >> Hub Transport >> Email Policies. Many Thanks

Hi, You should also be able to set the new address for existiing users through e-mail policies. Leif

Hi Agree with Leif. You can create a new EAP for users in that OU containing the new domain name and if you need it the existing name can be included too. Steve

Thanks for the prompt response, I did the policy it worked but I need to change the priority but unable to do so. I followed the following link for changing priority, http://technet.microsoft.com/en-us/magazine/dd553059.aspx I am unable to see the 'Change Priority' on right click. I can only see 'Apply, Edit, help' in EMC>>Hub Transport>> Email ADdress Policies. Many Thanks

You should be able to change the priority for all EAPs other than the default policy.

Verify that your account that you are using to make the change is in the Organization Administratiors security group.Jason Apt, Microsoft Certified Master | Exchange 2010 My Blog
