If you've experienced problems opening Office docs or OneNote notebooks from the SkyDrive app on your Windows Phone, you might need to reset the Office hub on your phone.
Resetting Office will delete the Office docs and OneNote pages saved on your phone. To backup important files, you can either add them to SkyDrive or follow the instructions later in this topic to email them to yourself. You can also email any OneNote pages that haven’t synced, or that are in Misplaced Sections. Also, when you reset the Office hub, you’ll lose anything that you’ve pinned to your start screen as well as any SharePoint sites you’ve bookmarked. You’ll have to add these again, later.
Resetting Office will delete the Office docs and OneNote pages saved on your phone.
On your Windows Phone, go to Applications, and then tap Office to go to the Office hub.
Tap the document you want to email (it will open), tap More, and then tap Share.
Tap the email account you want to send your message from, address it to yourself, and then tap Send.
On your Windows Phone, Go to Settings, tap Applications, and then tap Office.
Tap Reset Office.
