We've got a local Exchange server as well as an O365 subscription. I've got a new user who upon starting Outlook is being automatically connected to O365 instead of Exchange. I've removed his O365 link and tried setting up a new account with the Exchange option and it still selects O365 instead. I then tried setting up a new Exchange account manually on Outlook, but it automatically points to the O365 without ever giving me manual options. I'm unable to change the options for the account once setup too, the options simply aren't there.
For now I've got the user logging in with webmail, but I'd really like to get the Outlook client working for them. Any ideas on how to bypass this incorrect automatic O365 setup.
