The e-mail address you entered couldn't be found.

I receive the following message when sending an invite to one particular user. These emails addresses do not exist in the exchange any longer nor is it in the n2k cache file on any machine. Please help me isolate where these hidden recipients are...

The e-mail address you entered couldn't be found. Check the address and try resending the message. If the problem continues, please contact your helpdesk.

Look through your Active Directory groups, The person is probably in a distribution list of your First Administrative Group

Delegate most likely.
Someone has the user still listed as a delegate and they need to be removed.

But the user was removed completely from the system. There is a calendar invite that is sent to a valid user but then the invitor gets a kick back message showing that 2 people that are no longer in Active Directory cannot be found. So there is no distribution list or delegation with this users. I found several technet articles that say something about the old x.500 connectors are cached somewhere but I tried that procedure and nothing is working. They mentioned that the old emails may be stored in the outlook n2k file but they are not there either. How can I find where these invites are finding these old users that dont exist. Clearly there was a delegation or distribution that existed originally but as I said those users are no longer in AD anywhere so how can I find those old associations and get rid of them. Ive been searching for an answer for over a month now, please help!
Your help has saved me hundreds of hours of internet surfing.

This worked beautifully. After so much research and no article could point me to this simple delagate button.  I did not have to re-add or re-remove any users, they showed up as (not found) in parenthesis and when I tried to remove them I got the error,...you dont have rights etc. I had to add the write personal information option under the ADUC, advanced view, properties of the user, security tab, SELF item. Then I could remove successfully. Thank you for taking the time to help...
