Office 365: Change Update source


current config can be shown (not edited) at


Windows Registry Editor Version 5.00


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

Adjust UpdatePath from none to and (add) a channel property if you want to change it

  <Add OfficeClientEdition="32" Channel="MonthlyEnterprise"  UpdatePath="" >
      <Product ID="O365ProPlusRetail">
      <Language ID="en-us" />
      <ExcludeApp ID="Lync" />
      <ExcludeApp ID="OneDrive" />
      <ExcludeApp ID="Groove" />
	  <ExcludeApp ID="Teams" />
 <RemoveMSI All="TRUE" />
<Display Level="Full" AcceptEULA="TRUE" />
<Logging  Level="Standard"  Path="C:\Logs\" />
<Property Name="PinIconsToTaskbar" Value="FALSE" />

or simply?

	<Updates Enabled="TRUE" Channel="MonthlyEnterprise" UpdatePath=""/>
