After working fine for months I've just noticed that phone to ms outlook sync of calendar is not working. It started a few days ago but I can't be specific when. Pc to phone of calendar is fine, contacts sync fine both ways. I debranded from Vodafone and went to Froyo 10 days ago. Could this be the cause? Just installed the latest sync 2.0.33 from HTC - no change. It's a pain because I started using the phone to make work appointments, fortunately spotting the problems before any real damage was done with clients. Has anyone else come across this and if so found a fix? Many thanks.
