Not directly. I sync ACT! > Outlook via DoubleLook from CompanionLink Software. I then sync my 7250 directly w/ Outlook. So far it's worked pretty good, no duplicates, quick sync'e, etc. The only issue is that recurring appointments from ACT! have to be manually deleted from Outlook, as DoubleLook doesn't automatically delete them.
BTW, ACT! 2005 does suck big time. May be the version that pushes me to Outlook for good.
