Outlook: IMAP, POP3, and SMTP settings

Outlook.com supports access via POP3 and SMTP protocols. Below you can find the configuration settings for those protocols.

All Outlook.com servers (POP3 and SMTP) use implicit SSL (use ConnectSSL method).
SMTP server also supports explicit SSL (you can use Connect method and then secure the channel using StartTLS method)

Port: 993 (default)
User: pat@outlook.com

POP3

Server: pop-mail.outlook.com
SSL: true-implicit
Port: 995 (default)
User: pat@outlook.com

POP access must be turned on via web interface.
In the web interface click “gear icon” in the top, right corner, then select “Options”.

Depending on the UI version:

On the options pane click “Mail/Accounts/POP and IMAP”. In the “POP options” section select “Yes”.

On the options pane click “Connect devices and apps with POP” link. In the “POP” section mark “Enable”.
