ActiveSync 3.8 - how to get it, and why you need it
ActiveSync might be one of Microsoft's most-maligned pieces of software. It's been around for years, and most of its users have a love / hate relationship with it. When it works, it's fantastic, and when it doesn't, well, it's downright painful.
The sheer freedom that can be gained from being to be anywhere in your home or work office and check your email, or change the time for a meeting is completely destroyed if you install ActiveSync 4.x. So my suggestion is just don't. Luckily you can simply uninstall whatever version of ActiveSync you are using, then download and install version 3.8 from the fine folks at HPCFactor, and you're back in business.
