I have recently been trying to simplify a task of forwarding emails to colleagues by using a mail rule to autoforward to a select list of people.

Unfortunately it seems that the rule insists on running 3 times so the recipients receive 3 identical forwards.

I initially tried creating a rule where each of the forwarding recipient emails was listed (Outlook 2011 doesn't like having multiple addresses in one forward rule task and won't accept a mail group). Then I decided to forward it to an email address which is in itself just a forwarding email setup on my domain. The same thing happens every time... it performs the rule 3 times.

Any thoughts on what might be going on here?
