Hi Bjoern,
Those permissions allow to identify and display correctly the 'shared' mailbox type, but technicaly are not required for shared mailbox backup. Without those permissions, shared mailboxes will still be protected but displayed with the general 'user' type.
In v8, the permissions became mandatory while in earlier versions (7.x) they were optional to avoid any impact or interruption of existing backup operations.
Thanks!
