We keep password synchronization reliable by staying proactive and making sure users know how their actions affect access across Microsoft 365 and their devices. Even when sync works, cached passwords on devices can cause login failures. Windows, Outlook, and mobile apps often save passwords so users don’t have to keep typing them. If a password changes, those caches might still use the old one until you clear them out. The M365 sync establishes a synced dataset based on your M365 data and the filtering configuration of your sync.
