Issue with enabling Azure AD Connect staging mode
Hi All, Here is the story. There is a Windows Server 2012 with Azure AD Connect version 1.6.16 stopped syncing more than 250 days ago. I believe it happened because of Azure AD Connect version ...
Verify Azure AD Connect Installation and Connectivity
Before troubleshooting further, ensure the following:
- Azure AD Connect Version: Ensure that the version 2.4.21 of Azure AD Connect is installed and running correctly on the staging server.
- Network Connectivity: Confirm that the server with the new Azure AD Connect installation has network access to Azure AD and that the Microsoft Online Services Sign-In Assistant is installed and functional.
2. Staging Mode Configuration Check
The PowerShell cmdlet you tried seems to be missing the Microsoft.Synchronize.StagingMode parameter. If that’s the case, it suggests that you may be looking at incorrect or incomplete global settings. Here's how to correctly enable staging mode:
Check Existing Staging Mode Configuration:
You can use the following cmdlet to verify if staging mode is enabled on the current server:
Get-ADSyncGlobalSettings
To fix your issue:
- Ensure Azure AD Connect 2.4.21 is correctly installed on the new server.
- Enable staging mode properly through PowerShell or the Azure AD Connect Wizard.
- If the old server cannot be connected, remove it manually using PowerShell or clean up the old instance completely and then configure the new staging mode server.
