I'm using this function to send e-mails with a Sharepoint Hosted App with sucess, but I can only send e-mails to the users from the Sharepoint Site (I know this is for security) but My app will be used in a public web site where I can't validate the user will be in my sharepoint site (he don't need to be) and I need send the e-mail to him. There is any way besides change my application to Provider Hosted and use


In my c# code? It's a conversion from Sharepoint 2010 to Sharepoint 2013 and we can't add the cost of a provider hosting too this.

  • Sorry, they changed a lot in two years and I don't have a MailChipm account to check the new configuration, but as sharepoint public web sites will be dead in a couple months, you should check a migration for your web site for a new plataform. Commented Aug 12, 2016 at 18:56
