Daily send limit
About 300 emails per day, up to 100 recipients per message.
Authentication
SMTP AUTH must be enabled and modern authentication may be required on the account.
App password
If two-step verification is on, generate an app password at account.microsoft.com/security. Microsoft is moving personal Outlook.com accounts to OAuth/modern auth, so some third-party apps now need to connect that way instead of with an app password.
Covers Outlook.com, Hotmail, Live and MSN mailboxes. All use the outlook.office365.com incoming servers.

To send email through Outlook.com, set your outgoing (SMTP) server to smtp-mail.outlook.com and use port 587 (STARTTLS). STARTTLS on 587. Consumer Outlook.com does not offer SSL/TLS on 465.
For incoming mail, use the IMAP server outlook.office365.com on port 993, or POP3 at outlook.office365.com on port 995. Pick the exact values from the tool above and copy them straight into your mail client.
About 300 emails per day, up to 100 recipients per message. SMTP AUTH must be enabled and modern authentication may be required on the account. If two-step verification is on, generate an app password at account.microsoft.com/security. Microsoft is moving personal Outlook.com accounts to OAuth/modern auth, so some third-party apps now need to connect that way instead of with an app password.
Those caps make single-mailbox sending fine for personal mail but a poor fit for cold outreach at volume. Emailchaser spreads sending across warmed inboxes and manages deliverability, so you can scale without burning Outlook.com accounts.
What are Outlook.com's SMTP settings?
Outlook.com's outgoing (SMTP) server is smtp-mail.outlook.com. Use port 587 (STARTTLS). STARTTLS on 587. Consumer Outlook.com does not offer SSL/TLS on 465. Sign in with your full email address and password (or app password).
What is Outlook.com's IMAP or POP3 server?
Outlook.com's incoming IMAP server is outlook.office365.com on port 993 (SSL/TLS). If you prefer POP3, use outlook.office365.com on port 995.
Which port should I use for Outlook.com?
Use port 587 with STARTTLS wherever it's offered — it's the modern standard for authenticated sending. Port 465 with SSL/TLS is a solid alternative. Avoid port 25, which most networks block for client sending. Outlook.com's recommended value is above.
Why won't my Outlook.com SMTP connection work?
Check authentication first: SMTP AUTH must be enabled and modern authentication may be required on the account. If two-step verification is on, generate an app password at account.microsoft.com/security. Microsoft is moving personal Outlook.com accounts to OAuth/modern auth, so some third-party apps now need to connect that way instead of with an app password. Then confirm the host, port and security method match exactly — a 587/SSL or 465/STARTTLS mismatch will fail to connect.
Can I send bulk or cold email through Outlook.com?
Not at scale. About 300 emails per day, up to 100 recipients per message. Providers throttle bursts to fight spam, so pushing cold email through one mailbox hits limits and wrecks deliverability. High-volume outreach belongs on dedicated infrastructure that spreads sending across warmed inboxes — which is what Emailchaser does.
