  1. I think it would be a more useful use case and video if you showed how to create Company wide Signatures template… I am sure many more business would like to do that and some which dont have a developer to do that will even love a really step by step walkthru.

  2. Hello, thanks for your videos.
    Is it possible to use 1 service account to update signatures for every domain users ? The only way I imagine it right now, is to loop with "http_auth = delegated_credentials.authorize(Http())" for each users, it seems heavy. thanks
