Outlook not showing in Mail app. Not able to use my msn.com email on Mac Mail app.
Exchange or IMAP options do not work. Authentication fails and no way to set up manually anymore.
On iOS 26 or macOS 26 this is not an issue, likely because they were upgrades and not new installations as on the iMAC.
iMac (M3, 2023)
after having spend a day with ChatGPT and an attempt with Gemini to solve this issue, this morning I found out that after having installed a different email account and using the Exchange server option with authentication through Microsoft Authenticator it WORKED. Before this did not work, for sure manually it doesn't.
Issue might have occurred due to the fact that initially my msn.com email address - which is also my username for Apple account - was automatically linked to iCloud email account during install.
