Hi khplc24,

I understand you want the correct SMTP details for Outlook, and it is frustrating when different apps ask for different fields.

First of all, please note that this is a user-to-user forum, so contributors can share guidance and references, but do not have access to anyone’s account or settings.

I reviewed the Q&A Assist reply shown in your screenshot, and the general direction is correct for an Outlook.com mailbox. If you had a chance to try it, please share what happened and where it did not match your app’s setup screens.

To avoid repeating the same points, here are the extra details that usually decide whether SMTP setup works or not:

1. Authentication type matters. Outlook.com uses Modern Auth (OAuth2) for POP, IMAP, and SMTP in the official settings, so some older apps or devices that only support basic sign-in may not be able to complete authentication.
2. If your app is a POP or IMAP based mail client, POP and IMAP access is disabled by default in Outlook.com, and you may need to enable it in Outlook.com settings under Settings, Mail, Forwarding and IMAP, then turn on POP or IMAP and select Save.
3. For sign-in credentials, the official guidance is username equals your email address, and password equals your Microsoft account password. If a password is not recognized in some apps or smart devices, an app password may be needed.
4. For the exact SMTP server name, port, and encryption values, please use the official Outlook.com settings article here: POP, IMAP, and SMTP settings for Outlook.com.

One quick question to narrow it down, which app or device are you configuring SMTP on, and is the mailbox a personal Outlook.com or Hotmail account, or a work or school Microsoft 365 account?

I hope this helps, and once you share the app or device, I can suggest the most relevant next step without adding unnecessary checks.

Answer 2

For an Outlook.com account, SMTP sending uses your Outlook.com mailbox credentials and the Outlook.com SMTP server.

To make sure the account is set up to send via SMTP (POP/IMAP apps)

1. Enable SMTP access (via POP/IMAP setting)
   1. Sign in to Outlook.com in a browser.
   2. Select Settings (gear icon) > Mail > Forwarding and IMAP.
   3. Under POP and IMAP, turn ON either:
      • Let devices and apps use IMAP, or
      • Let devices and apps use POP
   4. Select Save.
   This allows external apps/devices that use POP/IMAP/SMTP to connect to your Outlook.com mailbox.
2. Use Modern Auth/OAuth2 in the mail app
   • Outlook.com requires Modern Auth / OAuth2 for POP, IMAP, and SMTP.
   • In the mail client where the Outlook.com account is added, choose OAuth2/Modern Auth as the authentication method if prompted.
3. Verify server details in the mail client
   • Incoming server (if using IMAP):
     • IMAP server: outlook.office365.com
     • Port: 993
     • Encryption: SSL/TLS
   • Incoming server (if using POP):
     • POP server: outlook.office365.com
     • Port: 995
     • Encryption: SSL/TLS
   These ensure the mailbox is correctly configured so SMTP sending will also work.

SMTP credentials for Outlook.com

For an Outlook.com mailbox, use the following SMTP settings in any app or device that sends mail via SMTP:

• SMTP Host name: smtp-mail.outlook.com
• SMTP Port: 587
• SMTP Encryption/Security: STARTTLS
• SMTP Username: full Outlook.com email address (for example, ******@outlook.com)
• SMTP Password: the Microsoft account password for that Outlook.com mailbox
  • If the password is not accepted, or for some smart devices, an app password may be required. See: “Learn how to add your Outlook.com account to another mail app or smart device” in the referenced article.
• Authentication Method: OAuth2/Modern Auth (where supported by the app)

These values allow sending email from the Outlook.com account through SMTP in compatible mail clients and devices.
