Step 1: Add a Signature Line

To insert a signature line:

Step 2: Add the Signature

You can add your preferred signature once the signature line is in place, but you must have a digital ID, and you can get one from a Microsoft partner. 

Also, ensure that the document's content is intact and there is nothing more to add. Then, you can add the signature as follows:

  • Double-click the signature line and a Sign window will display on the screen.
  • A quick prompt will display instead if you do not have a digital ID. Click the Yes button on the prompt to get an ID from a Microsoft partner.

  • Next, click on Sign to add the signature.
