Delta Drive, Delta Trust & My Drive · Sharing and comments
Can someone I share with pass it on to other people?
Short answer: Only with Reshare or Owner access, and never wider than they were given — same item or less, same level or lower, and ending by your share's date. Reshares appear in your Shared list for you to withdraw.
Only if you give them Reshare (or Owner). Even then, what they pass on can never be wider than what they were given: never more than the item they hold, never a higher level than their own, and never past the day your share ends.
A share somebody passed on appears in your own Shared list, marked with who made it, and you can withdraw it exactly like one of your own.
