I have one user who cannot open any form in Outlook 2003 SP3. Actually she only needs one but as this one did not work I tried others and each one fails opening with the following message:
"The form you selected could not be displayed. The form required to view this message cannot be displayed. Contact your administrator."
I tried - I think - everything. Cleared forms cache through Outlook and through file system. I changed Outlook profile from cached mode to non-cached. I tried settings the registry keys I found in some of the MS KB articles. I even created a new Outlook profile for her but to no avail and did a repair of the Office installation. so I am stuck here somehow and hope to get some help from a really Outlook expert.
