Hello, I'm running Windows Vista with outlook 2007. Whenever I open outlook lately I'm getting the following message.
Its showing up under the "tumbleweed desktop validator" pop up. It says "unable to validate certificate". When I click on it I see the below

"DV even description"

Certificate Revocation Status
Calling Application: Microsoft Outlook
Certificate Name: /C=US/ST=Washington/L=Redmond/O=Microsoft Corporation/CN=Microsoft Corporation
Certificate Issuer: /C=US/ST=Washington/L=Redmond/O=Microsoft Corporation/OU=Copyright (c) 2000 Microsoft Corp./CN=Microsoft Code Signing PCA
Certificate Serial Number: 61469ECB000400000065
Revocation Status: Unable to verify
Validation Protocol: CRL
Validation Url: http://crl.microsoft.com/pki/crl/products/CodeSignPCA2.crl
Revocation information not yet valid

My boss is getting annoyed by it popping up everytime and wants me to find a way to make it go away. I can't uninstall the program as its part of the PKI, but is there a way to remove the certicate thats having problems?

Part of your error message says "Revocation information not yet valid"

Maybe your boss's machine's system date is not correct.
