Machine: Windows XP, IE 8, Updated

When opening Outlook, or OWA security alert says Entrust OWA certificate has expired.

Have tried everything known to man:

1) Installed all ROOT CAs
2) Removed all certs with OWA
3) Updated Windows XP
4) Updated IE to 8
5) Reset/Restored IE


6) Cleared all temp internet files/cookies
7) Rebuilt mail profile
8) pinged, arped, gupdated, netiped, and flushed

The message keeps popping up and there is already a GoDaddy cert in place of it. No other machine has this issue. Any known solutions?

Have you viewed all local certs on that workstation? If you have can you see and then delete the old cert and install the new one?

I have deleted anything referencing OWA. There are Entrust Certs I did not delete, as they are not expired.
