Troubleshooting

If you don't see all your folders, right-click one of those that does show up and click Subscribe.  In the Subscribe window, check the folders you'd like to see and click OK.  If you want them all, click the first folder then hold down the Alt key and click the last folder.  Then, click Subscribe.  To prevent issues, you should uncheck non-email folders, like Calendar and Contacts, and then click OK
