Help with Mail Merge not working - greyed out

Hello.

I presently have Outlook configured as the default email client. (Have gone through the stock Apple Mail App to do this) I have rebooted several times and when I am doing up a mail merge document, the actual "generate email messages" is greyed out meaning I am unable to send a merged email.

Also, when I am in Word or Excel, and go to File "Share", the options to email are once again greyed out.

Does anyone have any suggestions? I have searched for hours to a solution but have not found any. I did find a couple terminal commands, etc but those did not work either.

I look forward to any and all help here.

Thanks,

Steve
