I also had this issue in Outlook 2003, but also in indows Live Messenger and Internet
Explorer 7.

I spend hours and hours searching the internet and could not find the solution. The
only possible solution you find on almost all forums (but does not help in most cases
is to repair the protected storage system provided registry key: http://support.microsoft.com/kb/290684.

So, here is a solution that is not even in the Microsoft knowledge base. It helped
me and hopefully many others. It was found because I new exactly when it started
to happen: after uninstalling a software program. The uninstall procedure removed
to many registry keys...


HERE WE GO...

Important: this solution contains information about how to modify the registry. Make
sure to back up the registry before you modify it. Make sure that you know how to
restore the registry if a problem occurs. View the following article in the Microsoft
Knowledge Base for information about how to back up, restore, and modify the registry:

It is possible that additional registry keys are missing. Below is a list of all

these keys again:
* Use the instructions provided on http://windowsxp.mvps.org/usershellfolders.htm
