Has anybody had problems regarding Windows Live Mail and the newest version of CCleaner. Is it possible that CCleaner interferes and deletes mails and folders in WLM?
Default CCleaner does not clean anything for live mail?
Are you using Winapp2.ini?
if so did you happen to notice the warning when you checked it off
This will reset the read counts, which will be recalculated when WLMail is started
even, if so the winapp2 entry only removes
RegKey1=HKCU\Software\Microsoft\Windows Live Mail|SearchFolderVersion FileKey1=%LocalAppData%\Microsoft\Windows Live Mail\Backup|*.*|REMOVESELF FileKey2=%LocalAppData%\Microsoft\Windows Live Mail|edb0*.log
so I don't think that this is your issue
