It may depend on the Exchange settings. Our server does not expand distribution lists and this solution works for me.
I have another rule that email with the condition 'sent only to me' to another folder.
There are some other rules based on a senders.
Every email that includes my address (i.e. someone added my address to the To or Cc) goes to separate folder.
Any emails that are sent to a Distribution list that I am part of stay in Inbox or is subject to other rules.
Outlook has additional condition 'where my name is not in the To box' that could be used to move email to other folder. But that will move emails CCed to you (and not to a group).
Can you help me with specific settings that you use to differentiate mails where you are the only recepient vs mails where you are in to with others. – Tamil – 2015-10-05T16:47:24.253
