Uninstall Office 365 Click-To-Run Updates

I wanted to uninstall an Outlook update but when I follow the instructions to uninstall the updates via Control Panel, I don’t see any Office updates listed there.

I’m using Office 365 Home Premium, which is updated automatically via the cloud and not Windows Update if I’m not mistaken.

Can I also uninstall updates then?

Update Options buttonOffice 365 installations indeed use a different update mechanism than the “msi-based” installations of Office 2013 and Office 2016. Office 365 installations are “Click-To-Run” installations which are essentially “always up-to-date”.

Reverting to a previous build number (from before the update) of Office 365 is possible but is very different from a msi-based installation.

Command Prompt

Command Prompt buttonTo revert to an earlier released version of Office 2013 or Office 2016 as an Office 365 installation, you must use a command line and specify the build number you would like to revert to.

  1. As the Office 365 installations are automatically updated in the background, you must disable the automatic updates first. This can be done in any Office 365 application via:
    File-> Office Account-> Update Options-> Disable Updates
  2. Open an elevated command prompt:
    1. Start-> type: cmd
    2. Right click on: Command Prompt
    3. Choose: Run as administrator
    4. Provide your administrator credentials or confirm the User Account Control dialog when prompted.
  3. Type the command below that applies to your version of Office and/or Windows
    • Office 2016
      cd %programfiles%\Common Files\Microsoft Shared\ClickToRun\
    • Office 2013 on Windows 32-bit
      cd %programfiles%\Microsoft Office 15\ClientX86\
    • Office 2013 on Windows 64-bit
      cd %programfiles%\Microsoft Office 15\ClientX64\
  4. You can specify the built number to return to in the following way:
    officec2rclient.exe /update user updatetoversion=<build number>
    • Replace <build number> with the build number that you want to return to. There is an overview of build numbers you can return to for Office 2013 and Office 2016.
    • Example to revert to the January release of Office 2016:
      OfficeC2RClient.exe /update user updatetoversion=16.0.6366.2062
    • Example to revert to the January release of Office 2013:
      OfficeC2RClient.exe /update user updatetoversion=15.0.4787.1002

    Reverting to build number 16.0.6366.2062 of Office 365. (click on image to enlarge)

  5. After pressing ENTER, a “Checking for updates” dialog will open shortly followed by a “Downloading Office updates” dialog. Once this dialog closes, the rollback has been completed.

  6. Open Outlook and go back to:
    File-> Office Account
    In the Office Updates section, it should now list the version that you specified.

    Office Updates - Update Options - This version will not be updated.

Important! Keep track of and re-enable Updates

Enable Updates buttonNow that you’ve disabled automatic updates, you must keep an eye on the updates yourself and re-enable it at the earliest opportunity as you might be missing out on newly released security updates and other feature fixes or even new features.

Updates for Office 365 for Office 2013 are always pushed out at least shortly after the 2nd Tuesday of each month (set a recurring reminder for it in Outlook!). Information about the updates are posted (with some delay) on the following page: Update Office 2013 or Office 365.
