Add your mailbox to Outlook
- In Outlook, choose Add account and enter your full mailbox address.
- If Outlook finds the settings by itself, it offers an IMAP account: continue. If it does not, choose the advanced or manual setup and pick IMAP.
- For a manual setup, enter the incoming (IMAP) and outgoing (SMTP) server names, ports and encryption shown for your mailbox. The username is the full address for both, and the outgoing server requires authentication.
- Enter the mailbox password, finish, and send yourself a message to check both directions.
Your server settings are shown in three places: on the page right after the mailbox is set up, under My mailboxes in My account, and in webmail under Settings → Apps & sync. Whether Outlook finds them by itself depends on what your mailbox's domain publishes; entering them by hand always works.
Good to know
- With two-step verification on, Outlook needs an app password; the mailbox password alone no longer signs in from mail apps. The scope Mail only (IMAP / SMTP) is enough.
- After you change the mailbox password, update it in Outlook too.
- An IMAP account in Outlook carries mail. Your calendar and address book are in webmail, and sync to phones and other apps over CalDAV and CardDAV: see IMAP, SMTP, CalDAV and CardDAV settings.
- Moving mail out of an Outlook.com or Microsoft 365 mailbox is a separate matter: see Move your mail in, and take it out.
