We tackle these by making sure the reset went through, checking Azure AD Connect, and confirming each device uses the right sign-in setup. 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.

Start by disconnecting the device from Work or School Account settings, then reconnect with the user’s updated password. Cached credentials on Windows or mobile devices can block the update. We tell users to sign out and sign back in with the new password. Running the Azure AD Connect Health tool gives you alerts for sync errors and interruptions. Keeping Azure AD Connect up to date and testing sync regularly helps password resets flow like they’re supposed to.

Reviewing Device Sign-In Settings

The Users Processed count will be 0 is there are no users in the synced dataset after filtering. The sync will fail if the groups you selected to load users from no longer exist in Azure AD. Typically this is because the selected groups have been deleted from Azure AD since the M365 sync was configured on your account. To get the sync working you will either need to delete users or have the user limit on your credential loop in Microsoft 365 account increased. Users I create within the Office 365 portal are fine, so I assume it is something to do with Azure AD Connect. We have reset the router, checked internet speeds, signed in and out of M365 apps, reinstalled apps and checked for Windows updates.
