We have a strange problem.
Setup: SBS 2003, Users on Windows XP with Office 2003.
Old users scenario: When the users leave, we delete the user and assign their email address as SMTP alias to the new user who takes over.
We have a secretary who manages calenders of two solicitors.
After we setup the latest new user account for the new secretary, when she send an calender invitation from her Outlook to either/both of the agents, she receives bounce back messgaes saying Your message couldn't be delivered to the following recepients. And the recepients listed are 3 old users who has left the company. Currently they are SMTP aliases to the new user who is sending the invitations.
Now I have checked for forwarding, there is no forwarding setup the exchange server end and also there are no rules in Outlook which is forwarding.
There is one thing I found. One of the solicitor's Outlook had Delegation setup to one old user and one new user. I removed this and this fixed the problem for that solicitory. So now, if the secretary sends invitation to one of the solicitor, she doesn't receive any bounce back messages.
But the second solicitor is a problem as he doesn't have any delegations setup at all and for any invitation to him sends back bounced messages.
This is not for just secretary, it happes if any user sends invitation.
I am quite surprised that this is happening. I do not suspect it to be corrupt install of Outlook as this has happened to the other solicitior as well although now fixed.
If someone can help, that will be great.
