I want to migrate from exchange 2010 to office365 and have now updated my autodiscover DNS entry.
After removing mail accounts and adding them back in, phones and other devices switch fine after the DNS change,
however; Outlook 2016 on prem still always points itself to our exchange servers. I've tried removing all profile data in case it had the autodiscover cached somewhere but now i'm wondering if it is an exchange 2010 / domain type setting.
My domain controllers are Server 2008 + 2012 in case that matters.
Can anyone help me out?
Thanks very much.
