Error Message - Unable to send invoices, receipts, statements via desktop email client with Sage50 2019.1

Just installed Sage 50 Canadian 2019.1 and now cannot send email invoices, statements, etc using a desktop email client.  Getting MAPI result code: 2 error message.

It worked fine using Sage 50 2018.3 an hour earlier, but since the update, now getting error message.

Anyone out there have a solution.

It seems to me this is an issue every time I update, but I can't remember for the life of my what I may have done a year ago when the same issue appeared.  Arrgggh!
