My 2210 was syncing fine, but I connected recently and it is no longer connecting. Message says"cannot connect for unknown reason. Check connections" etc...but all that's unchanged from before when it was working just fine???

Check all your connections first, but if they're ok, try unplugging them and them putting them back in. Seems simple, but sometimes works.

I had a similar problem and had to uninstall and then reinstall active Sync on my PC, then everything was fine.
