Associate a dedicated Group inbox (like in SharePoint), which we could Cc or Bcc for each email that could interest the Group.

In today's world communication by club executive to members is best serviced' via a group email. If Telstra Webmail can provide for the formation of a group why not Outlook!

If I receive an email as a part of a group alias and the sender has send it to multiple groups, it would be great to see the group I am a part of highlighted. This way I can see which group I am in and if it is not useful for me right now, I can unsubscribe. If you do highlighting on the to and cc list, that would be the best.
While the conversations option is handy, being able to move related emails into the conversation, similar to a folder, is helpful!
