E-mail Properties for contact addresses in Outlook 2010

Some people did not receive my attachments or received a winmail.dat file instead. I could solve this issue previously by changing the email properties of certain contacts from “Send using Outlook Rich Text Format” to “Let Outlook decide” or “Send Plain Text”.

Where is this option located in Outlook 2010?

E-mail Properties buttonThis option has been moved to the new “Address Card” pop-up which you get when you hover on an e-mail address or name which has been recognized as a Smart Tag.

Note: For an Outlook 2013 and Outlook 2016 version of this guide see E-mail properties for contact addresses in Outlook 2013.
