Hello, @Rohit Jalwaya
Welcome to the DocuSign Community!
How are you doing to see the completed envelope? Are you the Sender? If so, you can see the envelopes in the Manage page.
If you’re talking about the email notification to a recipient signs an envelope (Review Document button) so the error about expired link appears then it’s part of the security measures when a recipient does not sign the document in a 48 hours period.
For unauthenticated users, as a security measure, the envelope links in email notifications automatically expire after five clicks or 48 hours. Signers can easily request a new link, or, if they have a DocuSign account, they can access the document by logging into their account, even if the email link has expired.
I hope that helps!
