+# Outlook / Office 365 email accounts
+
+Odysseus email accounts currently use IMAP and SMTP with username/password
+authentication. That works for providers that still allow app passwords or
+mailbox passwords for IMAP/SMTP.
+
+Microsoft disables basic authentication for Outlook and Microsoft 365 in most
+modern accounts and tenants. If you try to add an Outlook account with a normal
+password, Microsoft may return errors such as:
+
+- `IMAP: AUTHENTICATE failed`
+- `SMTP: 535 5.7.139 Authentication unsuccessful, basic authentication is disabled`
+
+This is expected. Odysseus does not support Microsoft OAuth or Graph Mail yet,
+so Outlook / Office 365 accounts cannot currently be added through the password
+form. Use another email provider with app-password support, or track the future
+Microsoft Graph OAuth integration.
