Need to find unused distribution groups in Exchange 2010.

I use Exchange 2010. I have a large number of distribution groups created over the years. I need to find all the distribution groups that have not been used in the last 6 months and identify them and eventually delete them over time. How do I go about this?

The solution provided by Mahesh above is very efficient but you need to be hands on in Exchange Power shell. There are also 3rd party exchange reporting tools that can be bought that pull the reports for you once the exchange logs are adjusted. Also, a manual way to do this would be to pull reports from your email relay service about groups that have not been used in the last 6 months individually which would get the job done provided you have a few groups.

Agreed Anosh
This will be possible with 3rd party tools most probably, however as exchange admin the free method above should not be an issue
probably your exchange admin can follow that
