I have multiple email accounts that I manage via MAIL on Windows 10. (not via browser)  All are email addresses provided by Google with only 1 of which shows  *** Email address is removed for privacy ***. (This is the first one created in MAIL).  This email will not show file attachments.  The other emails have different "domain" (ie  *** Email address is removed for privacy ***,  *** Email address is removed for privacy ***).   These latter emails show the file attachments.   

How can MAIL be corrected to ensure all accounts show the attachments.

Regards

Bill
