I added a signature line to my Microsoft Word 2013 document (using Office365) and with inserting the signature image I get and error message:
The certificate you selected cannot be verified. Please check your network connection. Do you want to use this certificate?
If I continue, the signature is inserted with Recoverable Signature and it doesn't date stamp the signature.
I have a valid internet connection (attested by the fact that I am creating this question) and have confirmed that tracking is turned off, since I thought this may be the culprit.
Please advise.
