Our domain name was 'longername' and we purchased a 'shortername'
We had a member of staff who has left. I have removed her from the domain.
Now we have new finance groups set up, but because the old user still had some people who had not changed their contact details they still send mail to oldun@longername
So, the problem.
I have added oldun@longername as an email address to newun@shortname's exchange account.
What newun@shortname wants to do is when she receives an email sent to oldun@longername, she wants a reply sent to the sender saying this is an old address, here's the new one.
Now, because oldun@longername is not part of the domain and just an address attached to a user, I cannot create a rule, even if I add her as a contact in AD.
Any ideas how an smtp address attached to someone's account can have email replied to?
It doesn't have to be attached, but what else can I do?
I tried the quick and dirty methond, just deleting it, bit Finance aren't happy as some email to that address are auto generated, so a bounce back might not be picked up.
