Outlook 365 not connecting to on-prem Exchange
st84 Sorry guys for replying to an older thread but we have right now exactly the same issue. We have with the mail account online exchange deactivated AND did the Reg edit workaround but still the pc is not connecting to our on premise exchange server. Any other ideas?
CRHrchLenn anyway to fix this issue with exchange outlook combo on windows desktop client, e.g. windows 11 + outlook? Exchange server always defaults to office 365 online but never goes to on premise server directly. I can connect to my microsoft exchange server active sync no problem in windows and my iphone 14 pro mac to on premise exchange client works fine via my apple iphone mobile. Microsoft exchange active sync connections so that's a work around i guess but it should work as advertise, how to get microsoft exchange server to connect to on premise with custom domain name should be the title, i did enable autodiscover and DNS so that works but still does not work connecting exchange outlook to on premise, it just uselessly defaults to office 365 online and that's not even my exchange server domain!!
