I have now three users here who can no longer use the "Attach to email" function in Acrobat Reader DC. I am working for the same company so I tested my Acrobat Reader DC and it works just fine, as it does on some 50 other computers. All our computers are set up the same way, Windows10 64 bit with MS Office 365 and outlook as the default email client. If I uninstall Acrobat DC and reinstall it, then and it works just fine and opens with the default email handler, Outlook, for about 1 day. Then the next day or even sometime during the day I have to go thru that process again. I have even seen it work once and on the second try, fail. The cursor just sits and spins and never opens Outlook. I have even taken it a step further and done a “Repair” on Outlook after removing/re-adding Adobe Acrobat Reader DC. Thank you.
