eSignAnyWhere is an integration between Outlook and an electronic signature provider Namirial. In order to use the add-in users must have a valid Namirial account and enter its API credentials on the Welcome page. That page is accessible from the add-in and should be used by the Office365 administrators. Only enabled users by the administrator can use the add-in.
The add-in takes the content of the email and makes a context out of it. Title, recipients and documents become the envelope that gets sent for signing. Additionally, these can be changed to fit users’ needs.
