1. To see your "drafts", initiate the Mail app, make sure your'e in your Hotmail account in case you have more than one email account configured on your iPad.
2. Press and hold the compose icon (paper w/pencil). Your drafts should appear to you.
Now, go to Settings, Mail, Contacts, Calendars and tap on your Hotmail Account. Look for the heading "Mail Days to Sync". Make sure it is set appropriately. If you're unsure what is appropriate, set it to "No Limit". All of your mail should now sync to your iPad.
Now, as simple as the iPad is to use, it still requires some learning.
