How to Download Old Version of Office 365 on Windows PC
To download and install an old version of Office 365 on your Windows PC, you will need to use the Office Deployment Tool (ODT), which is a small program that lets you customize your Office installation. Here are the steps to follow:
Find out the version number of the old version of Office 365 that you want to install. You can use the following Microsoft website to see the update history for Microsoft 365 Apps for enterprise (listed by date): Update history for Microsoft 365 Apps for enterprise (listed by date). Choose the version that is previous to the current version or the version that has the features or fixes that you need. Note down the full version number, which is in the format of 16.0.xxxxx.yyyyy.
Download the Office Deployment Tool from this link. This will download a self-extracting executable file named officedeploymenttool_xxxxx-yyyyy.exe.
Run the executable file and extract its contents to a folder on your computer. You will see two files: setup.exe and configuration.xml.
Edit the configuration.xml file using Notepad or another text editor. Replace its contents with the following XML code: In the XML code, replace 16.0.xxxxx.yyyyy with the full version number that you noted in step 1. Save and close the file.
Open a command prompt window as an administrator. To do this, click the Start button, type cmd, right-click Command Prompt and choose Run as administrator.
Navigate to the folder where you extracted the Office Deployment Tool files. For example, if you extracted them to a folder named ODT on your desktop, type cd %userprofile%\\Desktop\\ODT and press Enter.
Type setup.exe /configure configuration.xml and press Enter. This will start downloading and installing the old version of Office 365 that you specified in the configuration file.
Wait for the installation to complete. You can check the progress by opening Task Manager and looking for the Click-to-Run process under Background processes.
When the installation is finished, you can launch your Office apps and verify that they are running the old version that you wanted.
