Error message when trying to accept meeting

[Richard]

I have been using Outlook 2003 on this computer for 3 weeks. The operating
system is Windows Vista Home Premium. Just today I started receive a error
message when trying to accept a meeting received. The message I received is
"The form required to view this messagecannot be displayed. Contact your
administrator.". This is not allowing me to accept, decline,..etc. What has
changed and how can I fix this?

Never mind. I found, while doing another search, a reply from Brian Tillman
dated 11/01/06 that corrected my problem.

Try clearing the forms cache. You don't state your Outlook version. For
Outlook 2003, it's Tools>Options>Other>Advanced Options>Custom Forms>Manage
Forms>Clear Cache>Close>OK>OK>OK.
