ANSWER 1
Score 80
I've found that for me this occurs because Outlook crashed for some reason but the Lync 2010 client still has a handle to the .ost file. Exiting Lync completely allows Outlook to restart.

- Run Process Explorer and choose "Find Handle or DLL" from the Find menu.
- Search for '.ost'. This will display all open handles to your Outlook data file.
- Choose to close all handles to your .ost file
- Start Outlook again
- optionally - run C:\Program Files (x86)\Microsoft Office\Office14\SCANPST.EXE

I couldn't find any processes that had a lock on my OST. Further, closing Lync provided temporary relief since I actually need both programs running. I finally just threw in the towel and uninstalled both office 2010 and Lync 2013. I then re-installed office 365 (with Lync). After 2 days, I have yet to see this error again.
