I can share of course but everything was written in similar posts ("Unknown
error").
Wmutil151 didn't helped me - it repaired an index file but the unwanted
message still were there.
I deleted (renamed to have a chance go back) WindowsMail.MSMessageStore and
when restarted the application all the e-mails were found (it took ap. 15
miunutes) and placed in a new folder. It was simple to move them to right
places.
