I use MS Outlook on my device during some weeks. And when I was talking with friend the connection interrupted and my phone froze (Nokia Lumia 520). At the same time Outlook was launched. After I rebooted the phone, I got a new problem. Most of my messages disappeared from Inbox. I was searching something like microsoft outlook inbox repair tool over the Internet. but I found nothing.
You may try to solve your issue with the help of transferring data to computer and apply following actions below....
If you can't open your Personal Folders file (.pst) or your Offline Folder file (.ost), or you suspect that your .pst or .ost data file is corrupted, you can use the Inbox Repair tool (Scanpst.exe) to diagnose and repair errors in the file. The Inbox Repair tool scans only the .pst or .ost file, not your mailbox on the server running Microsoft Exchange. The tool determines whether the file structure is intact. If it is not intact, the Inbox Repair tool resets your file structure and rebuilds the headers.
The Inbox Repair tool works on both the Microsoft Outlook 97-2002 Personal Folders File
(.pst) and the Office Outlook Personal Folders File (.pst) data files in Microsoft Office
Outlook 2003 and Microsoft Office Outlook 2007.
Scanpst.exe is installed when you install Outlook. It is located at: drive:\Program Files\Microsoft Office\OFFICE12.
