Outlook is open and working fine, I go to do something else on the computer
and when I return to Outlook I can see the pane showing all the folders on
the left, Inbox with message headers in the middle but the display pane
shows:

"Cannot display the folder. Exited without properly closing your Outlook
data file ......\....\Outlook.pst"

I have to shut down the program and restart it and all is ok for a while
then back to above.

This has happening frequently for the last 3 days or so. I've not done
anything different than normal in Outlook - I wouldn't know how to exit
Outlook without properly closing the data file.

Anything I can do to correct this?
