Outlook for Windows 10 PC Won't Send Group Email

I recently upgraded the Windows 10 Mail app to the Windows Outlook Mail app. In the people tab I created a new group. I have tried to send an email to the group and keep getting the error message "This message can't be sent right now. Please try again later.". I have tried sending by clicking on New Mail in the mail tab and entering the group name as well as going to the people tab and clicking on Send Email under the group Contact List.
