I have a SharePoint 2013 farm hosted in Azure. I have configured the SMTP service and Central administration 'Outgoing emails', but when I test document library alerts I do not get the email. I have checked that the email is not being blocked.
I have read that Azure does not support out going emails?
I have read about SendGrid, but this does not seem to address OOTB SharePoint functionality?
What do I need to do to get SharePoint Alerts working from Azure?
