Outlook 2007.
Got back to work only to find Outlook won't open as the pst file is not 'recognised'. Located the outlook pst file which is showing as 0Kb.................aaaaaaaaargh!
Tried scanpst.exe, no luck and also a repair Office install, no joy. I always do back ups of pst files, but in this case not for at least a year

Anyone come across this before?
Damned irritating.
