Madmatt/Mastershakes... If you remember the issue I was having, is that Outlook was not auto-resolving from previously sent to addresses or out of the contact list. Unfortunately, I know both of you had posted things that I hadn't yet had a chance to read. Could you re-post if possible? Thx! EDIT: Also, I don't know if this matters or not, but the problem started happening after I added this laptop to a domain environment. Previously, it was working locally (no domain attached) and working fine. When I transferred to the domain, I exported the entire inbox (including contacts), to a .PST. When I logged into the domain, I imported the .PST. Not sure if that matters, but I figured I would post that.
