Hi everyone, Have a single Exchange 2003 server (all clients Outlook 2003) and am having a few calendar based issues I'd like some help with; 1) When calendar appointments are made for one particular user, the person making the request always gets a bounce message saying that one or more recipients does not exist on the server. The failed recipient was a legit user, but has long since left the company and I can't find anywhere through AD where this non-existant user account has any permissions or forwarding set on the problem account. How might I go about finding why this non-existent user is being emailed calendar appointments for another user? 2) Person has shared their calendar, however it is empty whenever anyone tries opening it. I assume this is a sharing issue, however just wondering how I can verify exactly what the problem is without being able to remote desktop to the client PC?

Hi, Is the same error occurs when meeting request in sent from OWA & only for this user, when was the user deleted for which NDR is generated, for calendar sharing try to share it for user ID & check if some error occurs if not then there are no issue in calendar sharing it just a client machine issue.Ripu Daman Mina | MCSE 2003 & MCSA Messaging

Make sure the mailbox of the user doesn't have the unknown recipient as a delegate on their mailbox. >2) Person has shared their calendar, however it is empty whenever anyone tries opening it.

Give yourself Full Mailbox Access on that mailbox and create an Outlook profile on your machine. When you start Outlook, select that profile. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Hi, Regarding to the first issue, please assure that the user account is not exist in any group in your company when trying to compose a new appointment. As Rich mentioned, you can give your email box full Mailbox Access to the problematic user mailbox. For more information, please refer to the following article: How to Give a User Full Access to Another User's Mailbox Thanks.Novak Wu-MSFT

Hi, Check the users attributes for publicDelegates & publicDelegatesBL in ADSI.Remove the unknown user who has been added in delegates. Sathya
