Pointless forwards

Emails : A preferred medium of communication in large enterprises where the teams are spread across different time zones and geographies.

Email groups : A natural response for creating a single source for communicating information to multiple people.

Nesting of email groups : An email group can be part of another email group. Advantage : Easy to send information. Disadvantage: Easy to send anything to multiple people.

I am part of an email group called "Product A", There is another group called "Product B". At some point of time, "Product B" group was expanded to include "Product A". Advantage : I get all the updates automatically sent to the "Product B" group. Disadvantage: There is one person on my team who religiously forwards all relevant emails sent to "Product B" to the "Product A" emails.

Now I receive all those emails twice and I had to resort to setting up a rule in my outlook to delete the second copy as soon as it arrives.
