Hi, I have 500 Distribution Groups and 700 Mail Contacts in my Exchange 2010 Env't

we are going through a company merger and require us to add in a Secondary Email Address to the above.  We cannot use Email Address Policies for a few reasons, which I won't get into, so we are either doing this manually 1x1 or if can powershell it?  I am a newbie to powershell so would requite good step by steps please

Thanks,

Sorry -  not enough information.  Please consider using policies. If you cannot understand how to do this then post in Exchange forum for assistance in this deployment.
