I upgraded to Windows 10 Mobile on my Lumia 640 XL bought from this very nice deal. Microsoft Support knows nothing, but is anyone here having same problem?
Microsoft account is not detected by Outlook Mail, Outlook Calendar, and People apps, causing People app to crash. Adding the Microsoft account will say it was successful, but is still not added to the apps.

Shoulda gone Android…
(Yes I know this is an unhelpful comment)
If I was forced to give advice I'd say reformat the whole thing to factory settings.
