please can anyone help me in this case

Hi @m.tareq88 

We apologize for the delay in response.

To safeguard the privacy of recipients and facilitate the security of document content, the lifespan of publicly accessible URLs (provided to recipients via email) must have a finite life span. 

However, work processes can have very different tolerances for how long that lifespan should be.

For this reason, Adobe Acrobat Sign administrators can configure, at the account level, how many days a public URL should remain viable after it is generated.

Recipients that trigger an expired URL will be prompted with an option to have a new URL sent to the email address of the current recipient. Redirection to a new email is not allowed through this action.

How this can be fixed, please refer to the steps suggested in this help article and make the suggested changes in Adobe Sign Account settings: https://helpx.adobe.com/sign/using/adobesign-document-link-expiration.html 

Thanks,

Akanchha
