For some reason one of my colleague wanted to embed the excel file attachment in the main body of outlook letter he was typing. However he wasn’t getting through as the embedded image was large and showing content of file. The display as icon option was also not working.
Later we found by right clicking on the file image throws you option to convert the the file to other formats where the display as icon option is live. By selection the option the file is embed nicely in mail body.
I use office 2010.
