Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
The message indicates that the account is not being accepted with the current authentication method and that the device should use modern authentication (OAuth) instead of basic authentication. This is controlled by the Microsoft 365/Exchange configuration, so any change to allow or block certain auth methods must be done by the Microsoft 365 admin.
For the contacts not syncing to the Pixel 9 Pro:
- POP/IMAP accounts cannot sync contacts or calendar. Only Exchange ActiveSync/modern Microsoft 365 connections can sync contacts and calendar. If the account was added as POP or IMAP, only mail will sync and contacts will not appear in the phone’s Contacts app.
- The email provider must support Microsoft Exchange ActiveSync for contacts and calendar sync. Microsoft 365 and most major providers do.
- If the account used to sync and now does not, this is treated as a sync issue rather than first‑time setup. In that case, follow the Outlook mobile troubleshooting guidance for sync issues and, if it is a Microsoft 365 work/school account, involve the Microsoft 365 admin or technical support to review the account and device partnership.
- If this is a Microsoft 365 work or school account and the device is managed (e.g., via Company Portal/Authenticator), some Android models can have issues adding or syncing mail when another Microsoft app is installed. On such devices:
- Turn off power‑saving mode or adjust it so that Outlook and Authenticator/Company Portal are allowed to auto‑launch and run in the background.
- Disable power optimization for Authenticator/Company Portal.
- Open Authenticator/Company Portal first, then open Outlook so that the background auth app is running when Outlook connects.
If contacts still do not sync to the phone’s Contacts app even though Outlook itself is working, the Microsoft 365 admin should verify that the account is configured as an Exchange/modern auth account and that device access policies allow contact sync for that device.
