We have a resources exchange organization. User account is on main domain; contoso while exchange is on resources domain;adatum.

There is a trust between contoso and adatum. When we create mailbox, it will create a link mailbox as we know.

The user have to access a group mailbox. I would like to know what permission on group mailbox.

The full access on group mailbox shall look like:

Adatum\UserA

Or

Contoso\UserA

Why adatum\userA since by default it is a disable account

Really depends on what you want to achieve

You can open the mailbox 2 ways.

1. Contoso\UserA login to Adatum\UserA mailbox. it add Adatum\Group to the profile
in this case, you give access to Adatum\UserA

2. Contoso\UserA want to access Adatum\Group from Outlook directly without login to his own mailbox, then you will need to give access to Contoso\UserA


I will usually prevent method 2, but is your call.
IF you did it wrongly, the username/password will be prompted and not accepting the password. Nothing hurt.
