Unable to delete a recurring meeting (user was NOT the organizer but the organizer deleted the meeting without sending to participants) in Outlook 2003 Exchange mailbox on XP machine. When you double-click on the item in any view (including recurring appointments view) you get the "can't open this item" error. I've tried: Highlighting the item in the recurring appointments view and hitting delete. No luck. Right clicking on the item while in recurring appointments view (hoping to get a delete option). Nothing. Clearing the forms cache (both thru the Tools/Options/Other/Advanced/Forms and also deleting the the .dat file from the C: drive.) Changing the pdf addin value in the local user registry from 3 to 2. No luck. Any other suggestions? This wouldn't bother the user so much except the meeting 1. was set with no end date; 2. Reminder pops up continuously since user can't dismiss it... Any
