Office365 email taking priority over Exchange

Hi,

We have Exchange 2013 and Office365 Business Standard. For the time being, we use Office365 to activate Office installations on PC's.

Whenever we want to configure Outlook on a PC/Laptop, we need to do a registry entry of ExcludeO365Endpoint so that email configuration points to our on-premise Exchange instead of Office365.

The problem comes in when we want to configure emails on smartphones since they keep pointing to Office365. Is there something we can do so that Exchange is prioritized, please? Thanks

Hi @36584367

Yes, we cannot change this operation behavior. Here is a thread discussed the similar issue for your reference: Android/Apple Outlook app autodiscover to on-premise, exclude O365 endpoint
