Hello, I am using Exchange 2007. When I send calendar invitation to a user from Outlook or OWA, I receive an error message back. The user (Paul) does receive the invitation and an error message is always sent to the requestor, mentioning that another user is not found!! That user is deactivated in the Active directory and hasn't got any email account on my Exhcange server. I have check Paul's account and have no delevery option or any rules set up on Outlook. Would you have any idea of how to get ride of that error message?

It looks like you have a bad address in the Outlook address completion cache -- or in your Contacts folder since this happens with OWA, too. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Hi, Agree with Rich. If the issue does not happen when picking his address from the GAL, please clear the email address cache for outlook: Open C:\Users\YourUserName\AppData\Roaming\Microsoft\Outlook, change the outlook.nk2 or YourprofileName.nk2 file to xxxx.old. If you are using Windows XP or 2003, please go to the following folder: C:\Documents and Settings\"youruser"\Datos de programa\Microsoft\OutlookPlease remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Hello guys, Thanks for th imput but it does the same from OWA and from EMC I did a copy of the user's primarSTMPaddress and copy it into the To filed on Outlook application.
