I did some research but couldn't find the answer. Scenario: Forest1 and Forest2 with forest trust (bidirectional) Forest1 Excahnge 2007 SP3 Forest2 Exchange 2007 SP3 I run the ExchangePowerShell in Forest1 with the credentials of an account (Exchange Recipient Administrator) from Forest2. I try to mail-enable an account in Forest2. Nope. It is possible? Is there a switch to change the exchange org context? Thanks in advance Franco

After our testing we decided that it doesn't work. I think it will work with Exchange 2010.
