Find my Microsoft 365 server settings

Follow these Domain Striker steps to find your Microsoft 365 server settings for Microsoft 365. Keep credentials handy, save your work, and allow time for DNS or publish changes before you retest.

Use these common Microsoft 365 values when a mail app asks for servers manually.

• Incoming (IMAP): outlook.office365.com, port 993, SSL/TLS
• Outgoing (SMTP): smtp.office365.com, port 587, STARTTLS
• Username: your full email address

Prefer Exchange/Outlook automatic setup when the app supports it. Need more help? Call Domain Striker support at 402-STRIKER (402-787-4537) or visit help.domainstriker.com.
