You can do this with a wildcard Find/Replace, where:
Find = [!^13^l;]@\<([!\>]@)\>
Replace = \1
Do note that the above won't work if the actual email addresses have already been converted to hyperlinks.

Note: If you're regularly send emails to groups of people, create one or more groups for them in Outlook. That way, you don't need to input each recipient's email address individually.
