Original title: Windows Live Mail

Once again, I opened my Windows Live mail Version 2012 (Build 16.4.3528.0331) to see that a subfolder of my  "Inbox" folder is missing since last night.  It was the folder I was keeping the latest most important emails.

There were no Windows updates since I last opened it, except the daily Windows Essentials A/V, and I had made no adjustments to anything.  I have searched the computer fruitlessly for it.

This has happened before and it is very worrying indeed, not to be able to rely on my emails being where I filed them. Some need answers today!

Can anybody help me find it and also tell me why and how it happens?  Thanks
