Granting mailbox rights across forests in Exchange 2007

[astaylor]

I need to be able to add mailbox rights for users in a forest to a user in another forest. I have a trust setup between the forests. I dont have SP1 installed for exchange so there is no nice interface to grant these mailbox rights. what is the powershell command to be able to do this for a user in a different forest?

this is what i have tried:

Add-MailboxPermission -identity "Name" -User username@domain.local -Accessright Fullaccess -InheritanceType all

as well as:

Add-MailboxPermission -identity "Name" -User domain\username -Accessright Fullaccess -InheritanceType all

both result in a fail with this error:

Add-MailboxPermission : Failed to resolve the specified user or group "username@domain.local." If the user or group is a foreign forest principal, you must have either a two-way trust or an outgoing trust."
At line:1 char:22

the trust works perfectly as i am mapping shared drives across the forests successfully. i think i am just not typeing the right command.

thanks,
