Setting Up a Windows 7 Sync with Windows Mobile
When you click on Mobile Device Settings, the Windows Mobile Device Center begins the process of setting up a relationship between your phone and Windows 7. For this it initially requires you to give your Windows Phone a name so that you can recognize it in WMDC.
After this, it is time to check your sync settings.
By default, Windows Mobile Device Center will attempt to sync Contacts, Calendar information, Emails, Tasks, Notes, Mobile Favourites, Files and if installed Microsoft Office OneNote files.
As you can see, a considerable amount of data can potentially be transferred in a Windows 7 sync with Windows Mobile – as a result it is probably safer to clear the check boxes for Email and Files when setting up an initial sync.
Similarly, the Sync Settings link under each object to be synchronized can allow you to choose whether or not to sync data already on your phone that has been put there by a different computer. The less data involved in the first sync, the better, so you may choose to only sync one set of data.
