Vista - Vista IE7 with OWA 2003 Issue

Hi,

I am getting an error when trying to send email on Outlook Web Access
Exchange 2003, the errors I get, is I cannot respond to emails or send
emails out, I get an APPSCRASH IE 7 also an error that after logging off I
get "There has been an error removing certificates from this workstation.
error0x80070005): Access Is Denied"


This was after the common issue when composing an email from OWA. We
applied hotfixes 911829 to the server but the error message won't
go away. Any suggestions?


Thanks in advance,

Sankar Raja
