How to set up Microsoft 365 email in Outlook for Mac

This tutorial describes how to set up Microsoft 365 email in Outlook for Mac.

If you’ve never opened Outlook for Mac before, when you do for the first time, you’ll be prompted to set up an email account immediately, and can skip to the next step.

NOTE: For this tutorial, we will use as our test email account. You will need to change some of the settings to match your setup.

However, if you already have one or more email accounts set up in Outlook and wish to add a new one, simply click the Tools menu at the top of the screen, then choose Accounts

Click the + button and choose New Account:


The Set Up Your Email screen will appear. Input your email address, then click the Continue button.


Outlook for Mac will now try to auto-detect the settings to connect to the server. If successful, you’ll see a screen showing the correct settings and an option to Add Account.

However, if you get a notice that states: Sorry! We couldn’t find a match, then click the IMAP/POP icon to continue.


To verify your account settings, ensure they are set up as shown in the image above.

NOTE: The username is always the full email address you are setting up.

NOTE: If you are setting up a POP account instead of IMAP, you will need to use the following settings:

Incoming Port: 995

Outgoing Port: 587

Clicking Add Account will then give you a confirmation notice that the account has been set up successfully.

Default Email Account Settings (Office 365 Email)

Secure SSL/TLS Settings (Recommended)

Username: Use the full email you are setting up.
Password: Use the email account’s password.
Incoming Server:

  • IMAP Port: 993
  • POP3 Port: 995
Outgoing Server:

  • SMTP Port: 587
IMAP, POP3, and SMTP require authentication.
