Currently, when users 'Add account' in Microsoft Outlook 2016, the users are automatically configured (possibly through autodiscovery) to connect to 'https://outlook.office365.com/mapi/nspi/?MailboxIdemail@example.com' exchange server.
However, I would like them to be automatically configured to connect through our vanity URL, like 'https://exchange.server.consoto.com/mapi/nspi/?MailboxIdfirstname.lastname@example.org'.
And I would like the same with:
1) For SMTP: smtp.contoso.com:587 instead of smtp.office365.com:587
2) For POP, IMAP and Exchange Online: exchange.server.contoso.com instead of outlook.office365.com (with the respective ports)
3) For OWA: https://outlook.contoso.com/owa/ instead of https://outlook.office.com/owa/
How can this be configured?
