My version of WLM is Version 2009 (Build 14.0.8117.0416).

When I try to search for emails, it saying:  'Search results may be incomplete while Mail scans your messages.' Messages with the search words in the subject line are found, but are not found where the search words are, in the body of the message. I have tried rebuilding the Windows 10 index having checked that the WLM folder is included. I updated windows with the latest updates, but still doesnt work the search engine. Microsoft support told me that, since 2015 there is no support for windows Live Mail and I should try Office 365. I am really familiar with Windows Live Mail and I am using since 2009, in my opinion this is a windows update problem not a Live Mail support. Did anyone find a solution for this problem? 

Thanks,
