Hi,

current config can be shown (not edited) at

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\Configuration
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Office\16.0\common\officeupdate



Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Office\16.0\common\officeupdate]
"Updatepath"="http://officecdn.microsoft.com/pr/55336b82-a18d-4dd6-b5f6-9e5095c314a6"
"enableautomaticupdates"=dword:00000001
"OfficeMgmtCOM"=dword:00000000
"UpdateTargetVersion"="16.0.14430.20342"
"preventteamsinstall"=dword:00000001
"hideenabledisableupdates"=dword:00000001


Make a copy of the original configure.xml in installsource, for example myConfig.xml:

Adjust UpdatePath from none to http://officecdn.microsoft.com/pr/55336b82-a18d-4dd6-b5f6-9e5095c314a6 and (add) a channel property if you want to change it

<Configuration>
  <Add OfficeClientEdition="32" Channel="MonthlyEnterprise"  UpdatePath="http://officecdn.microsoft.com/pr/55336b82-a18d-4dd6-b5f6-9e5095c314a6" >
      <Product ID="O365ProPlusRetail">
      <Language ID="en-us" />
      <ExcludeApp ID="Lync" />
      <ExcludeApp ID="OneDrive" />
      <ExcludeApp ID="Groove" />
	  <ExcludeApp ID="Teams" />
      </Product>
  </Add> 
 <RemoveMSI All="TRUE" />
<Display Level="Full" AcceptEULA="TRUE" />
<Logging  Level="Standard"  Path="C:\Logs\" />
<Property Name="PinIconsToTaskbar" Value="FALSE" />
</Configuration>

or simply?

<Configuration>
	<Updates Enabled="TRUE" Channel="MonthlyEnterprise" UpdatePath="http://officecdn.microsoft.com/pr/55336b82-a18d-4dd6-b5f6-9e5095c314a6"/>
