Map onpremiseAD attribute to custom Attribute of AzureAD

Question

Map onpremiseAD attribute to custom Attribute of AzureAD

Ritik 0

I am requesting assistance with creating a custom attribute in Azure Active Directory (Azure AD) and mapping an Active Directory (AD) attribute to this custom extension attribute using Azure AD Connect.

I successfully created a custom extension attribute using a Microsoft Graph API call. However, I cannot find this custom extension attribute when attempting to map it from Active Directory to Azure AD in the Synchronization Rules Editor.

By default, custom attributes do not immediately show up in the Azure AD Connect Synchronization Rules Editor.

To refresh the schema:

Open Azure AD Connect on the server.
Go to Synchronize > Refresh Directory Schema and select Entra ID.
Wait for the schema refresh to complete.

Next, use Synchronization Rules Editor.

Create a new inbound rule:
Connected System: Select your on-premises Active Directory.
Attribute Mapping: In the list of target attributes, search for the custom extension attribute (it will appear as extension_{AppId}_attributeName).
Map the desired on-prem AD attribute (e.g., department) to this extension attribute.

Consider instead using directory extensions to extend the schema in Microsoft Entra ID with attributes from Active Directory. Details at

Hi Marcin,

Thanks for the suggestions! I’ve followed the steps to check the custom attributes using PowerShell, and I can confirm they are populated in Active Directory. However, I still cannot see the custom attributes in the sync rule editor even after refreshing the schema.

Is there any other method or troubleshooting steps you would recommend to get these attributes to appear in the sync rule editor? Any additional insights would be greatly appreciated!

Thank you!
