Outlook 2010 Creating a Contact Group from an Email

I received an email for a work group with a large distribution list. Instead of just replying all, I wanted to be able to compose a new message using my contact list for addresses. I found the answer here: http://office.microsoft.com/en-us/outlook-help/create-and-edit-a-contact-group-formerly-distribution-lists-HA010354963.aspx

Rather simple once I learned that the Members field will accept a large amount of copy and pasted addresses.

Create a Contact Group by copying names from an email message    

1. In the message that you want to copy the names from, click the names in the To or Cc box.
2. Right-click your selection, and then click Copy.
3. In Mail, on the Home tab, in the New group, click New Items, then click More Items, and then click Contact Group.
4. In the Name box, type a name for the Contact Group.
5. On the Contact Group tab, in the Members group, click Add Members, and then click either From Outlook Contacts or From Address Book.
6. At the bottom of the Select Members dialog box, in the Members box, right-click, and then click Paste.
