Important announcement about AAD Connect password writeback

Friday, October 5, 2018

If you are using an older version of Azure AD Connect and have password writeback enabled please ensure you are using the latest version.

Azure AD Connect versions 1.0.8641.0 and older rely on a service that will be retired on November 7th, 2018. For more information please read, How to: Migrate from the Azure Access Control service. If you are using AADC version 1.0.8641.0 or older and have enabled password writeback, your users may lose the ability to change or reset their passwords at that time.

To address this issue, you should upgrade the Azure AD Connect instance for their organization.

AAD Connect 1.0.8641.0 was released June 2015. I certainly hope that you have upgraded your AADConnect since, but it's worthwhile checking to make sure you are not impacted.

To check the version of AAD Connect, use File Explorer to navigate to C:\Program Files\Microsoft Azure Active Directory Connect and check the properties of the AzureADConnect.exe file. The latest version of AAD Connect, as of this writing, is 1.1.882.0.
