If you are the "Sender" of the envelope, go into your DocuSign account and locate the envelope under the Manage, Sent folder and select "resend". This sends a notification to the current responsible Recipient (s).

Thanks for response. I would like to resend to 109 of 264 people. Is it required to check 109 boxes to resend or is there a way to drill down to "waiting" and select "all" ?

You can send out multiple "resends" by checking the box in front of each envelope and hitting "resend" at the top of the DocuSign page. I believe it limits you to "resending" 50 notifications at a time.
