every so often, when accepting a meeting, or sending a meeting request out, I get a bounce back message stating that a specified user could not be reached. the User was taken out of the system months ago.this is using outlook 2007, on a windows xp machine, in an exchange environment.steps taken to resolve this was checking to see if said user was still showing as a delegate, rebuilding the outlook profile, running command line switches to clear client and serverside rules as well as clean free busy. also usded the mfcmapi tool and couldnt find anything that way.Is there anything else i can try to resolve this problem?1 person needs an answerI do too
