Is there any documentation from Microsoft about the forest trust requirements in a GalSync scenario when one of the organizations has their Exchange org in a Resource Forest attached to disabled user accounts with linked mailboxes (user accounts residing in separate production forest)?
I found a blog entry stating that with linked mailboxes a trust is needed but I cannot find any official Microsoft documentation one way or the other. Any help would be appreciated! If possible, we would like to accomplish this without the trust but due to the Resource Forest scenario a trust may be required. Thank you in advance!
