Notes

Connect with Microsoft 365 sign-in (OAuth). Microsoft retired IMAP/SMTP passwords for Outlook.com and Microsoft 365 — an app password will not work.

How to Connect Outlook / Microsoft 365 to InflowMail

1. 1 Create an InflowMail account or sign in to your existing account.
2. 2 Go to Settings > Connected Accounts and click Add Account.
3. 3 Select Microsoft 365 and sign in with your Microsoft account. We use OAuth - we never see your password. Microsoft retired IMAP/SMTP passwords, so an app password will not work. A work mailbox often stops here with "Need admin approval" if you are not a Microsoft 365 admin. Send this page to the person who manages your company email, then connect again after they accept. Until then, use Outlook on the web. Personal @outlook.com accounts do not need that approval.
4. 4 Your emails will start syncing immediately. The initial sync may take a few minutes for large mailboxes.
