Happened just now.

Many of the historical storage folders have suddenly vanished.  I can see a few ......but 90% of them have gone.

Mail inbox works normally.

I have checked the folder tags to make sure all can be seen.  All OK on that front.

I have used the Windows Essentials repair programme.  No effect.

Where have my folders gone?  They contain literally 10 years plus of emails in various categorised folders. 

This is a global....HELP>>>>>>>     

Thank you
