How to have a secondary email address in exchange 2010
We have exchange 2010 implemented and we have user called Graham Clark and his main email address is email@example.com and all the emails are received in this address in our organisation. He says that he wants a secondary address as firstname.lastname@example.org.
Is there way to have this address without having an account in AD or what is the best way to do this. I have around 20 users who needs a secondary address .Any tutorials will be helpful
