Office 365: Convert AD Sync Users to Cloud Only

In any infrastructure AADConnect syncs the users at the best to Azure AD and this is a proven truth.

Looking into today’s paradigm, many companies would like to end their On-premises presence and move 100% cloud.

This means we have to decommission domain controllers and manage all identities from Azure AD.

So, the question comes how to convert AD synced objects to Cloud only Azure AD objects.

Here are the steps:

Step 1. Run the PowerShell to stop ADsync from office 365.

-Install Signin module

-Install module

Install-Module MSOnline

-Connect to office 365

Connect-MsolService


Provide password on the next screen

-Disable Dirsync

Set-MsolDirSyncEnabled -EnableDirSync $false


-Verify the status

(Get-MsolCompanyInformation).DirectorySynchronizationEnabled

Step 2. Uninstall AADConnect from on-premises server

-In Program and Features, select “Microsoft Azure AD Connect” and click uninstall.


-Select Yes.


-Click Remove on this screen


-We should see all uninstalled.


Step 3: Wait for 72 hours.

-Open Azure AD and check Users Sync status today

-Open Azure AD and check Users Sync status after 72 hours.
