When sending email to any contacts from your address book in Outlook, some recipients receive a winmail.dat file attachment that shows up in some clients such as Gmail and Yahoo web mail. In Outlook, the attachment icon is displayed but no attachment shown.
This issue is fixed in build 16.0.8229.2073. To install the fix, go to File > Office Account > Update Options > Update Now.
