Can some one assist me with the EMS syntax need in order to add a cross forest permission to a user on a mailbox and also how to make it available in outlook 2010. The below syntax is what I have tried and it seems to go through with no error but i cant get it to show up in outlook:
add-mailboxpermission -identity "mailbox" -accessrights fullaccess -Inheritancetype All -user firstname.lastname@example.org
I then went to map the mailbox in outlook but the name is unresolvable, and i tried to user the FQDN. We do have a 2 way trust between our domains. Am I missing anything?
