Firstly I notice that all the contact photos were missing from the iPhone after I'd gone to great length over time to have a large percentage of the 3000 contacts with a matching photo. I thought syncing the iPhone would replace them from Outlook but it has just removed them from there too. I realise that they are probably gone now but it?s a bit of a mystery as they have been fine for over 2 years and there is no apparent settings to control it. Any ideas so it won't happen again.
