I just cloned the SSD on my Microsoft Surface Pro to a new Microsoft Surface Laptop 3, using Casper.
Now Outlook 365 on the new laptop will say "Needs Password - Click to enter your password for this account" in the bottom right, Clicking just results in the password box just flashing on the screen and disappears.
Notifications also pop up with this message:
Provide your password to use Microsoft Outlook with your firstname.lastname@example.org account. Click here to enter your password.
But that vanishes when I click on it.
