here i configured full mailbox access on both users (x & Y).
x have full Mailbox Access on y and y have full mailbox access on X
same way after installing exchange 2000 post sp3 rollup update,
configure security for send as permission & it is working, but not like as
before installing post sp3 rollup.
Scenario:
user x can read the mail of user y and reply it but instead of sending the
mail ,he save the mail & move that mail from darft folder to y's draft folder.
After that Y read that mail & try to send the mail but he can't, gets the
error : """you don't have sufficient permission to perform this operation on
this object.See the folder contact or system administrator."""..
user x is able to send using address from Y. but not able to perform the
above task.

Need Help ASAP.
