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.

Login & Sync Errors: Personal & Business Microsoft 365 Accounts on Same Device

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 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 clear Outlook credentials manager 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.



Password sync usually fails when credentials don’t update between Microsoft Entra ID (Azure AD) and your on-premises Active Directory. Most of the time, the problem comes from timing delays, configuration mistakes, or cached credentials on devices that don’t pick up new passwords. We check that Microsoft Entra Connect (Azure AD Connect) runs the latest version and password sync is on. Keeping things updated helps avoid compatibility issues between on-premises Active Directory and Microsoft 365. If problems stick around, we rejoin the Office 365 sync problems and login fixes devices to Microsoft 365 services.

Common Causes of Office 365 Password Reset Sync Issues

• Windows, Outlook, and mobile apps often save passwords so users don’t have to keep typing them.
• 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.
• At NetTech Consultants, we help organizations keep Microsoft 365 running smoothly and securely.
• So, if you just changed your password, there might be a short window where your old password still works and the new one hasn’t reached every system.
• 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.
