I've been having problems with Outlook for a while and just reloaded the 365 Office suite on my Windows 10 computer.  Problem Statement:  When I try to add a .jpg or .pdf file to an email, the recipient receives a .dat file that is unreadable, not the .jpg or .pdf file.  

 

Is there a setting I can change in Outlook or something else I can do to fix this problem?  Or will I have to change my mail application to something other than Outlook.  

 

Thanks in advance for your help....   Steve
