Chronic issue with Outlook "cannot open this item"

Posted on 2007-08-02

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?

    Detect and repair and reinstalling Office will usually not fix these problems.
    Does the problem follow to another machine?
    If it does not, then there are only three fixes for Outlook issues that I find work...
    - new Outlook profile
    - new Windows profile
    - wiping the machine.

    I discovered it was a third party plug-in within Outlook that caused the issue.

    Which third party plug-in was causing this problem for you as I have 1 user having this problem and I can't figure out why as it is very random. Thanks!!

    In my case, it seems the attachment was corrupted, and that was causing the issue
