When I use the user b11 and b12 i can look in the mailbox of another user. When I ask the dropbox of an user for uploading and double clic on this mailbox I can see the mail etc of that user.
This problem is not in every accesgroup. I enclose in you private mail the accesgroup which is wrong. I can not test further becouse of my hollyday and busy becouse of moving to antoher house. Hans
