When my users send an email with attachment from Microsoft Navision they get a visual bug as illustrated below. It happens when they send an invoice from Nav, Outlook opens with a new message dialog with the attachment. When you hover with your mouse cursor over the "To" field, the 3 additional fields appear. At that point you can't send the email anymore
All the users got this issue in a period of one week, so I think it's a Office / Windows update the caused the issue. I contacted our Microsoft Navision reseller, but they haven't seen this issue before.
Any thoughts on this?
Nav Client version: 8.0.43389.0
Outlook 2016 build: 1703
