Hi,

 

Just pushed this config to my test tenant

 

 

It looks like its working at my side without any issue... 

 

 

Could you check out your chrome admx it contains this part and if it arrived at your device (policymanager /registry)

 

<policy class="Both" displayName="$(string.ExtensionInstallBlacklist)" explainText="$(string.ExtensionInstallBlacklist_Explain)" key="Software\Policies\Google\Chrome" name="ExtensionInstallBlacklist" presentation="$(presentation.ExtensionInstallBlacklist)">
<parentCategory ref="Extensions"/>
<supportedOn ref="SUPPORTED_WIN7"/>
<elements>
<list id="ExtensionInstallBlacklistDesc" key="Software\Policies\Google\Chrome\ExtensionInstallBlacklist" valuePrefix=""/>
</elements>
</policy>

    Hi Rudy_Ooms_MVP 

     

    So I have checked the ADMX and all is there: 

     

    Here is the policy I set for blacklist too:

     

     

    Here is the registry via the device: 

     

     

    Any ideas where Im going wrong? Is it best we do this via powershell or is it clear where I have made a mistake? 

     

    Thanks again for your continued help
