We are now running Exchange 2010. Previously ran Exchange 2003. We have several domains in our forest. Previously, if someone from another domain, lets say for the sake of this question it was the "Houston" domain, wanted to have access to a mailbox in the "Toronto" domain in active directory I would assign that users account houston\%username% to the mailbox toronto\%mailbox% with whatever level of permissions were being requested. However, since we have upgraded our domain controllers from 2003 to 2008 and upgraded exchange from 2003-2010 I no longer have the same permissions tab in AD as we use to.
Previously I would just go to the resource in AD and right click it, go to "Exchange Advanced" and then click on "Mailbox Rights" then
See picture:
Then I would assign the persons account to the resource by selecting the domain to whom the user wishing to have access to the resource originates from. (see below - you can see that all of the trusted domains are listed)
However, in Exchange 2010 when I click on "Manage Full Access" the "Picker Scope" only detects the parent domain (see below) to assign permissions for other users and not cross domains.
I would like to know how do I add permissions for accounts from doamins other than my own in Exchange 2010.
Please let me know if you have any questions or comments, thank you in advance for your assistance.
Thank you, Chris
