Hi, can someone point me to somewhere, where I can find more details about supported configurations/devices for HTTP 451 redirects?
What infrastructure parts do really have to support HTTP 451 redirects in order for a moved mailbox to automatically reconfigure in iOS9/10 (integrated Mail/Calendar/Contacts App).
Also, does anyone know which EAS Versions are shipped with iOS9 and iOS10, as this also seems to be a limiting factor.

Looks like my scenario is working. I just didn't work for me, because I had MFA active and iOS Mail wants an app password after the mailbox move.
