You probably have enabled provisioning. This used to work when set to  
'Allow non-provisionable devices' but as far as I can tell, the only  
setting that currently works is 'Disable (not recommended)'. But even  
with that setting some clients won't work while others run flawlessly.

I don't recommend to use ActiveSync with the build-in Mail service in  
Windows 10.
