Fixing ActiveSync woes with Outlook 2007

Microsoft ActiveSync

Now here’s a remarkable (even blogable) thing: my slow Windows Mobile to Outlook ActiveSync synchronization woes now appear to be a thing of the past. But not before running into some difficulties.

After I upgraded from Microsoft Outlook 2003 to Microsoft Outlook 2007 ActiveSync point-blank refused to connect to my beloved O2 Xda Orbit.

Not only had I upgraded Outlook itself, I’d also moved from the older “Outlook 97-2002” PST file format to the newer “Outlook 2003-2007” format. I didn’t even realise that I had been working with the older format. That must go back to my upgrade from Outlook 2000 to 2003.

My usual solutions did nothing to help:

  • Remove the Windows Mobile 6 device from the cradle and then reseat it.
  • Reboot the Windows Mobile 6 device.
  • Reboot the Windows XP device.
  • Run scanpst.exe on my Outlook.pst file.

I went for a solution-hunt on Google, and discovered that disabling the advanced nework functionality might just do the trick. And you know what: it did.

What I did

  1. Click Start > Settings
  2. Click on the Connections tab, and you see this:

Windows Mobile 6 Settings

  1. Double-tap the “USB to PC” icon
  2. Now untick the only option available: “Enable advanced network functionality”.
  3. Click OK button (top right).

Now everything seems to be running faster and more responsive on my O2 Xda Orbit (not just connecting to ActiveSync but accessing menus, calendar data, contacts, applications start faster), and it connects to ActiveSync first time, even straight after a system reboot. Previously it would always object, and I’d need to remove it from the cradle and leave it until after the system had completely booted up.

But …

The only thing is that I’m not entirely sure what “advanced network functionality” is. I’m not sure what I’ve disabled, what I’m missing out on … any ideas?
