Find Outlook.com IMAP and SMTP settings (Hotmail and Live)
Find the personal Microsoft mailbox servers, enable IMAP, and understand the OAuth2 requirement.
Check whether AeroMailer can sign in
Use this guide for personal Outlook.com, Hotmail, or Live mailboxes. Microsoft requires Modern Auth (OAuth2) for these endpoints. The AeroMailer Outlook.com preset fills server details but does not offer Microsoft OAuth sign-in; this release cannot directly authenticate to OAuth-only Outlook.com IMAP or SMTP. An app password is not a substitute for OAuth2 on those endpoints.
Find and enable the settings in Outlook.com
- Sign in to Outlook.com in your browser.
- Open the gear icon, then Mail → Forwarding and IMAP. Allow IMAP access and save if you are setting up an OAuth-capable client.
- Record the full email address as the username. For IMAP use
outlook.office365.com,993, SSL/TLS. For SMTP usesmtp-mail.outlook.com,587, STARTTLS. Both require OAuth2.
Use an appropriate connection
Use Outlook web or an OAuth-capable client for this mailbox. To send from AeroMailer, use another SMTP account you are authorized to use; it will not sync your Outlook.com inbox. Work or school users should follow the Microsoft 365 guide. See Microsoft’s Outlook.com settings.
