Hello,
For my company I sign a lot of contracts using an Adobe Acrobat digital signature and electronic ID. After I sign and lock the contracts I save them to my hard drive. I have noticed that a few contracts signed in the last year are missing my electronic signature. I checked both with contracts uploaded to Salesforce, and the same contracts that are still saved on my hard drive. The signature is missing! What is the reason for this? I did not delete the electronic signature profile or ID. Do the signatures expire? The contracts were signed in the last year and untouched since they were final.
Thanks!
