I upgraded my laptop to Windows 10.  When I receive e-mails in the Mail app from one individual,  I cannot see that I have attachments.  On my other machine running 8.1, the same emails show the attachments.  I sent myself an email from 8.1 mail and I did see the attachment in the Windows 10 mail program.  The emails from another user did not show in 10 but did in 8.1.  Any help will be appreciated.
