You might not be able to. I have a newish O365 account that staunchly refuses to use any protocol but MS Exchange. POP3 or IMAP at best timeout, but feed the same credentials into any exchange/outlook client and I'm in. I've also noticed in the main O365 account I pay for, plus a couple set up for me by past consultancies, was that my login ID was always an @office365.com, @live.ca (!) or some other MS-owned domain. I could merrily send and receive e-mail under the company domain, but the credentials were always at the same domain. Unpopular opinion: Outlook is the best e-mail client. In many technical and UX aspects it may be the worst, but it is how corporate e-mail is done, and that's that. Stewart
