we have a user "x" who shares a adressbook to a lot of people.

When a user who had such a share is being deleted, the user "x" is not able to add or to delete an other user for sharing.
The adressbook crashes. (Gw 8.01 client)

I recognized, that with an old GW 6.5.7 client it works. The old 6.5.7 client asks if the deleted user should be cleared.

How to enable this clearing for gw 8?
