Permissions

[K.V]

We run exchange server 2003 SP1 on windows 2000 server. our domain is on
Windows 2000.

I have all possible (domain admin., enterprise admin., ) permissions on the
domain.

We have a user (X) on whose mailbox, calendar
- I had full permission once.
- another employee (Y) had permissions to setup his appointments etc.

This other employee left and i deleted her account including her mailbox
from the domain.

Now whenever somone sends a meeting request to 'X' i get the request and the
sender gets a NDR saying the system failed to deliver the request to
'Y'..which doesn't event exit on the system.

This is what i have tried so far.

- Delegates
- mailbox rights.

no Luck.

Can somone help.
