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 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
