I did visit this forum about 4 times, Nov. - Dec. 2014; always the same misery.

Check mail, close WLM. Shortly after closing, a message pops up "Recovering unused disk space" and "The folder is in use by another application".

[The only mail today was Staples-junk, McAfee is up to speed 24/7]. I was already suspicious, opened WLM, the contents of every folder accumulated between Dec. 30 [the last wholesale loss] and Jan. 17 2015 ARE TOAST, GONE again.

I was experimenting using WLM +Word Pad rich text as editor, wipe outs.

I activated Office 365 and used OUTLOOK [instead of WLM + Word Pad], wipe outs, contents periodically wiped out, so I aborted Office 365.

The craptop is ~ 8 months old, used it for 100 hours maybe?

I don't use the "Cloud " space or "One drive" [knowingly/deliberately] yet it appears, something periodically purges all mail folders.

Of course, Microsoft/Dell are out of reach, NOBODY talks to you in spite of the box still being under warranty.

Anyone, a suggestion how to avoid this software terrorism?
