Live@Edu - Open another mailbox
On Live@Edu, users have the option to open another mailbox (click username in top right corner). What does this do exactly?
The help says "To obtain full access to a mailbox other than your own, contact your help desk or system administrator". I'm the admin and I don't know.
What do I need to do to allow other users to access a mailbox? I've seen threads relating to running PowerShell scripts. Is there way to change mailbox permissions through the Live@Edu GUI?
