Read here to get a BT port below com 9

[Guest floepie]

This worked wonders for me at least. There is a good write-up floating around regarding how to activesync over BT. What the article fails to mention and what might incorrectly be assumed is that the incoming com port should be 7 to match the serial outgoing com port 7 on the phone. The incoming BT com port on your PC can be anything that is single digits. However, for some, getting there has not been so easy.

Several installs of BT stacks can leave phantom ports in use and new installations will simply grab successive unused com ports and assign them BT status. Time to get them back. The key is that you must first unhide them in the device manager. You cannot simply do this within the module itself - a feature by design by MS. You must enter a series of commands using MS's command line interface. Once you can see all the ports that are supposedly in use by either phantom devices or apps no longer in use, you can simply uninstall each one of them individually. If you only have one BT device (your smartphone) and you are using MS's BT stack, you can even get rid of all your BT com ports. After you reboot, windows may or may not reinstall three BT com ports. If it doesn't, you can always add them manually as per the BT pairing instructions, but this time, you will have BT com port numbers in the single digits, which activesync can then recognize.

Follow the MS reference on how to 'unhide' all devices.
