One particular user cannot connect to Exchange, One Drive, Teams, etc. We have a local AD. He can sign on to his PC and access local resources. This issue arose a few days ago when he changed his local AD password. I am not seeing any errors in Azure AD connect. I can confirm that other details of his account synchronize, such as Description, Organization details, etc. I have changed his local AD password a couple of times this evening and waited on synchronization to occur. I have also forced a logout from all his O365 sessions from admin.microsoft.com. I know that password synchronization is working for other users because I created a new user this morning, and that user is able to access cloud apps such as Exchange, etc.
In addition, I changed my password a few minutes ago and tested it with cloud resources after the synchronization ran, and I could log in with the new password. This issue appears only to affect his user account.
I attempted to purchase Azure support a few minutes ago but kept getting an error. :-(.

2023-06-30T15:57:28.4666667+00:00 Thank you for the reply. I tried all of the steps outlined in the article and everything (that ran successfully) looked normal. The
ADSyncDiagnosticsmodule completed with the following error...Get-ADSyncConnector: C:\Program Files\Microsoft Azure AD Sync\Bin\ADSyncDiagnostics\PSScripts\ADSyncDiagnosticsUtils.ps1:86 Line | 86 | $adConnectors = Get-ADSyncConnector | Where-Object {$_.ConnectorT … | ~~~~~~~~~~~~~~~~~~~ | Could not load type 'System.Web.Util.Utf16StringValidator' from assembly 'System.Web, Version=4.0.0.0, | Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. No AD Connector is found. Password Hash Synchronization does not work in the absence of AD Connectors. -

2023-06-30T17:47:02.78+00:00 This issue is resolved now. I changed the user's password again today, waited for the synchronization, and tested. It works. I didn't do anything to fix it. Thank you for your help.
