Chronic issue with Outlook "cannot open this item"
I am running Outlook 2003 on a Windows XP machine with service pack 2 that connects to a Exchange Server 2003. Often times, I am getting a message when I try to open calendar items or emails. It says "Can't open this item. You do not have sufficient permission to perform this operation on this object. See the folder contact or your system administrator." I close Outlook and reopen it. Once I do this, everything is ok for a while. Then it starts happening again. I have done numerous things to overcome this. I've done a detect and repair in office, changed windows profiles, and uninstalled and reinstalled Office 2003 to no avail. Any other suggestions?
