Using Outlook for iOS in business environments for email and scheduling
Hi arab hawamdeh,
Welcome to the Microsoft Community.
I understand that you mentioned an error related to imap-mail.outlook.com.
Due to the introduction of modern authentication, outlook.com does not support connecting IMAP/POP and SMTP in Outlook. So please check the following:
If you are using the Outlook app for iOS, due to modern authentication, Outlook/Hotmail no longer supports connecting IMAP/POP and SMTP.
If you are using Apple Mail to configure Outlook/Hotmail, we generally recommend selecting outlook.com for configuration.
If you wish to configure using the IMAP protocol, you need to confirm with Apple Mail support whether they support modern authentication for configuring IMAP.
