VB.Net legacy product - MAIL.SEND() crashes on Office 365 (MAIL.DISPLAY() works!) Using Microsoft.Office.Interop.Outlook

Rik Evans 0

We have an ancient class CreateEmail, that has suddenly stopped working with Office365 installs on our customers remote desktops.

Class uses Microsoft.Office.Interop.Outlook

We have an 'autosend' flag, that either sends the email once created, or displays to the user.

The code either calls Mail.Display() or Mail.Send()

Mail.Display() shows a perfectly formed email, and manually clicking 'Send' sends the email.

Mail.Send() crashes... (Lost exact message, but wasn't helpful).

Anyone else experience this? Solutions?
