The sync will fail if it can't find any users that comply with your filtering preferences or the system's requirements for user records. The system requires that users have a first name, last name and a valid email address that conforms with your domain lock if enabled. The sync does not delete users but rather sets them to inactive. The idea is to provide a recycle bin of users who you can delete when you no longer need them.

We tell users to sign out completely and remove stored credentials from Windows Credential Manager or their device’s keychain. Sometimes, rejoining the device to Azure AD or just reauthenticating in Office apps does the trick. This pops up a lot after admins reset a password in the Microsoft 365 admin center. That changes the password in Microsoft Entra ID, but not right away in your local Active Directory. You end up with mismatched passwords between the cloud and your local network. The Users Loaded count will be 0 if all users fail to meet the system's requirements for user records.

What to do when Office 365 password reset doesn’t sync across devices

On Windows, open Credential Manager, pick Windows Credentials, and remove anything related to Office 365 or Microsoft 365. On macOS or iOS, delete stored credentials from Keychain Access. To update from Azure AD Sync resolve Outlook not sending emails fast to Microsoft Entra Connect, see the upgrade instructions.

Bad settings in Azure AD Connect cause lots of password sync failures. If password writeback isn’t enabled or the service account doesn’t have the right permissions, new passwords won’t update in Active Directory. That leaves people locked out with their new password on the cloud but not locally. We show users how to reset passwords using approved methods like the Microsoft 365 portal or self-service password reset (SSPR). If someone changes their password only in the cloud or just on a local system, things can get out of sync pretty quickly.

Reviewing Device Sign-In Settings

The Summary sheet on the spreadsheet attachment of your sync summary includes an Updated User Count and User Limit. These figures will give you an impression of how far over the limit the account is. Sync failure alerts do not always include a full summary or Fix Outlook and Office 365 Errors 2025 attachment, you can run a test sync to obtain this data.



We start by checking that Azure AD Connect is running and password sync is enabled. diagnose Office activation conflicts If it’s in Staging Mode or a recent change didn’t trigger a full sync, passwords won’t update in Microsoft 365. If a password reset in Office 365 doesn’t sync across devices, it’s usually because of incomplete synchronization, old credentials, or device caching.

• The Users Loaded count will be 0 if all users fail to meet the system's requirements for user records.
• We focus on restoring sync between Microsoft Entra ID (Azure AD), on-premises Active Directory, and user devices so everyone gets back in without headaches.
• Keeping things updated helps avoid compatibility issues between on-premises Active Directory and Microsoft 365.
• These figures will give you an impression of how far over the limit the account is.

You should run a test sync after re-authenticating the sync to ensure it is working. Devices sometimes keep using cached passwords even after a successful sync. If users access multiple apps with the same login, we make sure Single Sign-On (SSO) settings line up so the new password works everywhere in Microsoft 365. If there’s a delay, we manually trigger a password sync using Microsoft Entra Connect.
