We also remind users to refresh their Office sign-in token by signing out of all Microsoft apps and signing back in with the new password. Azure AD Connect handles password sync, but it runs on a schedule—usually every 30 minutes. 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.

Calendar Sync Issues in Outlook

We turn password sync back on by running the Entra Connect configuration wizard and picking Customize synchronization options. If a password reset in Office 365 doesn’t sync across devices, it’s usually because of incomplete synchronization, old credentials, or device caching. We tackle these by making sure the reset went through, checking Azure AD Connect, and confirming each device uses the right sign-in setup. Check that your password change actually synced between your on-premises Active Directory and Microsoft Entra ID (formerly Azure AD). If disable faulty add-ins in Outlook it didn’t, a few targeted checks usually restore access—no need to keep resetting your password over and over.

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. Outdated credentials get stuck on devices, password sync gets turned off, or Microsoft Entra Connect just doesn’t update like it should.

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. First, we check that the password reset finished in Microsoft 365 or Microsoft Entra ID. The user should log in to the Office 365 web portal with the new password. If the old password still works, the reset probably hasn’t synced. 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.
