Hi Kenneth,
Thanks for your response.
I have had a look through the link, so in terms of the permissions.... of course we can not assign this directly to the queue. But the owner of the queue has both the permissions showcased in that link.
So I am not to sure why it is still flagging the user does not have send as privilege? If I go into the email as a system administrator who has send on behalf of another user ticked, and try send an email from the queue the error still appears which is why I am confused.
Any suggestions appreciated.
