365 Offline Installer - Microsoft Office

Here are the key features of the Office 365 offline installer:

1. No Internet Required During Installation

• After you obtain the offline installer (e.g., via the Office Deployment Tool or certain Volume License channels), you can install Office on a PC without an internet connection.
• Useful for computers with limited, slow, or unreliable internet access.

Step 5: Create the Installation XML File

To install on an offline machine, you need a slightly different XML file (or you can modify the existing one). Create a new file named config-install.xml: microsoft office 365 offline installer

<Configuration>
  <Add OfficeClientEdition="64" Channel="MonthlyEnterprise" SourcePath="C:\ODT\Office">
    <Product ID="O365ProPlusRetail">
      <Language ID="en-us" />
    </Product>
  </Add>
  <Display Level="Full" AcceptEULA="TRUE" />
</Configuration>
