Full installer for Microsoft 365 Apps Enterprise

Where can I get the full offline installer for Microsoft 365 Apps for Enterprise? I need it because deploying the setup file alone to multiple users consumes too much internet bandwidth (via Manage Engine)

Dear @Mohd Marezuan Ahmad Marzuki,

Good day! Thank you for posting your question in the Microsoft Q&A forum.

We apologize for any inconvenience you may encounter when using our services/ products. Based on your description:

You can use the Microsoft 365 Deployment Tool (ODT) to download and install Microsoft 365 for Business in offline environments. This tool is specifically designed for enterprise use and operates via the command line.

While an internet connection is required initially to download the installer files, the actual installation of Microsoft 365 can be performed offline using a customized configuration.xml file.

For detailed instructions, please refer to the official guide titled Use the Office offline installer

For more detailed guidance on using the Office Deployment Tool (ODT), please refer to the official documentation.

I followed the steps in the guide below: Microsoft Support – Use the Office offline installer

Configuration used: Installed the 64-bit version of Microsoft 365 Apps for Business.

When I ran the command:

c:\odt\setup.exe /configure installOfficeBusRet64.xml

I received the following error message: "Couldn't install – We couldn't find the specific configuration file. Check the file path and file name."

Dear @Mohd Marezuan Ahmad Marzuki,

Please ensure that the following requirements are met:

The configuration file name is correct: Double-check that the file is named exactly installOfficeBusRet64.xml and not something like installOfficeBusRet64.xml.txt (which can happen if file extensions are hidden).

The file is in the same directory as setup.exe: Both files must be in the same folder, e.g., C:\odt\.

Correct Command Format:

Open Command Prompt as Administrator, navigate to the folder, and run:

cd C:\odt .\setup.exe /configure installOfficeBusRet64.xml

This ensures the command is executed from the correct directory.
