OUtlook doesn't recieve response when sending meetings

I'm stumped. I have a user who is not recieving meeting notices when people are sending her them via Outlook 2003 (SP3). Also, when she sends meeting invites and people respond, she is not recieving the responses. Have tried repairing Office but no luck. Any ideas? Thanks

Fixed it. Here is one solution in case anyone comes across this down the road:

 You have added a Delegate and selected 'Send meeting requests and responses only to my delegates, not to me'. (e.g., Tools | Options | Delegate).
 You have your calendar set to auto-accept meeting requests.
 You set 'Author' permissions on your calendar. This allows a person to open your calendar by choosing 'Open a Shared Calendar' and schedule a meeting directly on your calendar. Therefore, no email notification is sent.
