Thank you David. Slightly different to my results (see file attached).
Also, I don't have Office365. My outlook.com emai is from my Microsoft account webmail rather than the Office Suite.

That said, I did login via outlook.com, found settings/mail and it does show me that pop3 is disabled and that it's now imap, with the same settings that you showed in your pic. So perhaps that why my outlook settings in calibre didn't work ... because I've thought it was pop3 and not included office365 as part of the address. I'll try those now.
