Here's the deal: I went on to the Outlook forum and tried to resolve this issue, however they told me I needed to come here because they were unable to find a resolution. I have 2 users each sending out appointments. Sometimes by group and sometimes by choosing addresses from the GAL. Either way, the same few email addresses send out a "recipient does not exist" error, even though the recipient does get a copy of the appointment in their mailbox. Here is information about my system: Windows 2000 SP 4 server running Exchange 2000 SP3 on dual Xeon with 4Gb of Ram. Outlook 2002 clients Exchange running about half full. Below is what we did on the other site to diagnose and troubleshoot. I am at my wits end with this thing. Oh, by the way I should also mention tht we had a catastrophic failure of the exchange server and had to rebuild it using a backup of the databases. There was some mention and thought that this may be an SID issue, however I can't confirm it. Thanks for any assistance you can render.

Be sure and include all information, including the Exchange version, the Outlook Client versions, and all symptoms, and what you have done so far to troubleshoot.

I can't believe that with the cumulative knowledge on this board, that I am unable to find anyone who can assist us, or even wants to take a stab at it. Unbelievable. Isn't there even one of you with enough guts to try? -Mac

This is generally a delegate issue, and where I would start looking; A script to find delegates in your domain by Kristina Waters http://krisdev.blogspot.com/2005/06/vbscript-for-all-domain-users-write.html A few ways to get rid of themhttp://support.microsoft.com/kb/909638 A more agressive way to get rid of them http://support.microsoft.com/kb/253557

I found the Solution. As Kblock stated its within those links. What you need to do is downloadThe Microsoft Exchange Server Information Store Viewer utility found herehttp://www.microsoft.com/downloads/details.aspx?familyid=3D1C7482-4C6E-4EC5-983E-127100D71376&displaylang=enat the bottom of the page. It can be run on any computer dosnt have to be the server. Once downloaded you need to give yourself access to thecertain calender that is causing the issuesand add it as a mailbox to your outlook. Once that has been done follow the instructions on the link above and it should fix your problem.
