My husband uses Outlook 2000 at work and we have 2003 at home. When
he sends me an invite, it comes through as text. When he uses his
blackberry I get a vcalendar email.
How can we change this so that I receive invites that I can accept
and be entered in to my calendar?

He sending you the invitation from Outlook in a format other than Rich Text.
He has to make sure you are receiving Rich Text in order for the invitation
to appear as it should.
