You don't say how large the organization is. The *safe* way to do this is to create mail-enabled contacts in the AD for the users on the other e-mail systems. In this way you can still enable recipient filtering and avoid sending tons of undeliverable e-mail to another system by sharing your address space with them. The alternative is to share your address space which will send all messages whose address cannot be resolved to the other e-mail system: http://technet.microsoft.com/en-us/library/bb676395%28EXCHG.80%29.aspx --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
