Hi,I have Exchange 2007 on separate box and Sharepoint on Separate box. for example, i am user so my emai address is user@exchange.com and if i have contact in sharepoint so my contact mail address is contact@sharepoint.exchange.com. Because Exchange is the relay server for Sharepoint.\Now i want to change contact@sharepoint.exchange.com to contact@exchange.com,Please share your comment.Thanks

Guys, Simply i created receipient policy for sharepoint as well and now both exchange and sharepoint document libraries emails addresses are same. Thanks Amit Rawat
