I have a new HTC Trophy with Windows Phone 7. I have set up Activesync and all works fine apart from a synchronisation with Deleted Items. If I read an email on the device, then delete it, it moves correctly to deleted items (viewable both from the phone and Outlook), however it shows the item as unread in Outlook.
Only a small problem but it is being used by my boss and he finds it annoying. Any advice someone can give as to why this happens? Incidentally I have activesync set up on an iPhone and it doesn't show this behaviour. Is it just another early release bug?
