Follow these steps to get the email account working on the Android phone.
- Install and set up Outlook for Android (recommended)
- Install the Outlook app from the Google Play Store.
- Open Outlook, choose Add account, and sign in with the Microsoft 365 or Outlook.com email address and password.
- If calendar and contacts do not sync after adding the account:
- In Outlook, go to Settings > tap the account that is not syncing > Reset Account.
- If it still fails, go to Settings > tap the account > Delete Account > Delete From This Device, then add the account again.
- If prompted to set up the account as IMAP or POP, cancel and instead choose the option that uses Exchange/Outlook (so that calendar and contacts can sync). IMAP/POP will only sync email.
- If using another mail app on Android (Samsung Email, built‑in Email, etc.)
- Prefer Exchange/ActiveSync if offered so that mail, calendar, and contacts all sync.
- If only IMAP/POP is available, only email will sync. For example, in Samsung Email:
- Open Samsung Email > Settings > Add account.
- Enter email and password, tap Manual setup.
- Choose IMAP or POP3 if Exchange is not available (email only).
- Use the incoming and outgoing server settings from the provider. For Outlook.com or Microsoft 365, the outgoing SMTP server is:
- Outlook.com:
smtp-mail.outlook.com
- Microsoft 365 for business:
smtp.office365.com
- Security type: TLS, Port: 587.
- If the account still cannot be added or does not sync
- Make sure the email provider supports Microsoft Exchange ActiveSync if calendar and contacts are required.
- If using Outlook for Android with a Microsoft 365 work/school account and mail will not sync on some Android models:
- Turn off any power‑saving mode that prevents apps from launching other apps.
- Allow Microsoft Authenticator or Company Portal to auto‑launch and disable battery optimization for it.
- Open Authenticator/Company Portal first, then open Outlook and try again.
- If a Google account is being added to Outlook for Android and a 403 or disallowed_useragent error appears, install Google Chrome from the Play Store, set it as the default browser, and then add the account again.
- If setting up for the first time and calendar/contacts do not appear
- Confirm the account is not configured as IMAP/POP if calendar/contacts are needed.
- If Outlook on a PC is available:
- Set up the same email account in Outlook on the PC using the Exchange protocol.
- Send a test email and create a test calendar event.
- Close Outlook, restart the PC, reopen Outlook, and confirm the event is in the calendar.
- Check the Outlook app on Android again; if needed, restart the Outlook app from Settings.
If these steps fail, use the “Troubleshoot email setup on mobile” guidance referenced in the Office install troubleshooting article for more device‑specific checks.
