Hi

For an approval task, I pick a group which is an Active Directory group. 

If I tick "Create individual tasks for all group members", I'm getting this error:

Error in request approval action. The user to assign the task to has resolved as blank text.

If I untick "Create individual tasks for all group members", there are no error however, no email notification is sent. 

This is using the same group. 

My questions are:

- In theory, are the email notifications supposed to be sent when assigning an approval task to an AD group ? Like is nintex capable of getting the members of the group from AD and then send email to each? 

- Why would the error about blank text occur in one case and not another  ?

- When you use an AD group in sharepoint, is it talking to AD directly or is it actually a Sharepoint Group that happens to be the "synced" version of the AD group ? (I suspect the latter but I'm a newbie self trained SP admin)

Many thanks in advance
