I’m not really a fan of Outlook. I find it to be overly complex for most users, hell, even for seasoned technology professionals, but it is the defacto standard email/contact/calendar tool for corporate America.
This free plug in from Microsoft (free? Microsoft? Wow, Bill musta been distracted that day.) alegedly allows sending SMS messages via an attached GSM phone (such as my much loved Audiovox 5600).
I’ve not yet tested it and considering the source I take it’s operation far from granted. I don’t send many SMS messages but I can see the utility in such a function.
