I have seen this question/issue on multiple forums and nobody seems to have an answer/fix yet. I included an e-mail submit button for my form, and when I practice submitting, everything sends fine. However, if I distribute the form (to allow for tracking, etc.) I get an error pop-up window that reads "Check names" "Microsoft Outlook does not recognize '1. double click the attachment'". What I mostly don't understand is "1. double click the attachment" is part of the directions/content in the e-mail after they actually, successfully submit the form. Why is the content auto-populating as part of the mailing address?? After you "Show More Names" and search for the correct recipient(s), you have the same error pop-up again with the 2nd step that's show in the content of the e-mail: "2. Acrobat will prompt you to select a responses file", until you select the recipients again by clicking "show more names". Then the e-mail populates, with "Completed Form&body=Instructions to add this form to a responses file: email@example.com?subject=Submitting" as a recipient, as well as the 2 recipients you had to search for.
Does anybody know why this happens and how to fix it!?
