Hi, thanks for reply(my answer is in Blue Italic)
Deleted mail folder and recycle bin are not the same oK thanks
Your email sounds like its corrupted. You may want to download and try the most current, Windows Live Mail 2011 Yes I know Live Mail but not sure if it is ok or not, I mean I used to Windows mail that is not using Microsoft mail.
I have a hunch. Try with a clean boot. If I will try what will happen? http://support.microsoft.com/kb/929135
Bet its your maintenance software, or maybe antivirus
For further information that mail does not go to recycle bin, it goes to deleted mail folder. This is not a bin problem.
EDIT From the email client you have to set up send deleted mail to deleted items folder What are steps?
Are you using pop3 or Imap settings? I gues I am using Pop3
Is your folder set up to handle large emails? I think more than 1 GB
Did you check settings?
Tools > Options > Advanced > Maintainance> tick 'Empty messages from Deleted Items folder on exit > Close Attaching screen shot. Sorry everything is Japanese Thank you very much
