Hi All, The Validate Signature is Greyed out, hence I am not able to add this to the trusted certificates and not able to validate the signature either. Please help
It's unsigned, there's nothing to validate...
It is signed, just not visible when I open it in Adobe Acrobat Reader DC.
It's not signed properly, then.
Looks like issue with Adobe itself. I re-installed Adobe and now I was able to verify the signature. Thank you.
