I mean searching for a message that isn't locally synced. For example, my client is set to sync the last 2 weeks, but if I'm looking for a message from 2 years ago, I'd like to search on the email server and then download/view that message. This is a feature that works on the Windows Phone 7 Mail app, but I can't find it on the Windows 8 Mail app. It makes the app fairly useless unless you want to sync your entire email history (I don't really need to store 5 GB/ 8 years of email locally).
