Hello,
According to your description, there are users who are constantly being notified to update their Microsoft passwords. Here are some things you can try:
- Some devices or applications have old credentials (e.g., old passwords) cached, so warnings of invalid passwords are constantly triggered. Have the user open the Credential Manager, find the relevant account entries, and delete them.
- If a user is using the same account on multiple devices, and some devices are not updated with a new password in a timely manner, those devices may constantly try to log in with the old password, triggering a notification. If the device is found, ask the user to manually update the passcode on the device. Make sure to update your new password on all your devices, including phones, tablets, and more, especially apps that are bound to auto-sign-in (e.g., Outlook, Teams).
- In some cases, synchronization between Azure Active Directory and on-premises AD (if any) may be delayed, resulting in the new password not being applied to all services immediately. To reset your password and sync manually: Azure AD > password reset > manually triggered. Check the user's password policy settings to make sure there are no configuration restrictions or conflicts. Check device activity and logs: Check the user's sign-in activity in the Azure AD audit log to determine if any devices or apps are constantly trying to sign in with the old password.
- The user account may be bound to some services or applications (such as mailbox, Teams, etc.), and these services may continuously try to log in with the old password in the background. In Azure AD, admins can choose to force users to sign out on all devices. Go to the Azure Management Portal > User > select the User > Sessions option to force the user to sign out of all active sessions.
I hope this information helps.
Best regards,
