I'm trying to build an Outlook Add-In using javascript. I couldn't find a way to retrieve the current user's signatures. I need that in order to insert the propper signature according to the selected FROM email (which the user controls while composing a message). Any clues?
Currently getting user's signatures in an add-in is not a part of the product. We track Outlook add-in feature requests on our user-voice page. Please add your request there.
Feature requests on user-voice are considered when we go through our planning process. https://officespdev.uservoice.com/forums/224641-general/category/131778-outlook-add-ins
