We're using Sharepoint Foundation 2013. I have a workflow (2010 workflow) which will send an email when some1 adds something to the list. Tried it both ways - add the AD group to the email action in the workflow and tried to add the SP group with the AD group inside into the email action in the workflow, but none of it seems to work. Only if i add AD users one by one to the SP group it send the email. And thats not the way we want to proceed.
If the SharePoint Group or Ad Group has the Group Email, then the email sent the mail to group email Id.
There is no Out of the box way to achieve this.
Some possible workarounds
