I recently downgraded from Windows 10 back to Windows 7 Home Premium and am experiencing problems with Windows Live Mail as a result. It seems that Windows Live Mail has recovered hundreds of old messages and will not allow me to delete them. I have managed to get them into my trash but now they are stuck. Nothing happens when I select "empty trash" and when I try to delete each message individually, I receive a prompt saying cannot delete, unknown error - no error code. I suspect I will have to reinstall windows live mail but I thought I would throw the question into the abyss first! Thanks!
