How to Undo an Automatic Outlook 2016 Upgrade
Question details
The user wants to revert an automatic Outlook 2016 update due to undesirable interface changes, missing contact information, and an incorrect count of outgoing messages.
- Product
- Microsoft Outlook 2016
- Device & OS
- not provided
- Scenario
- After Microsoft Office automatically updated, the user experienced a changed interface and sync issues, prompting the need to roll back to a previous build.
- Observed behavior
- Outlook displays an updated interface with altered contact info and shows more outgoing messages being sent than the user actually composed.
Before rolling back your Office installation, ensure you have your product key accessible and back up your Outlook data files (.pst or .ost) to prevent potential data loss during the downgrade process.
Revert to an Earlier Version Using the Office Deployment Tool
The most reliable method to undo an Office 2016 update is to use the Microsoft Office Deployment Tool (ODT) with a specific configuration file.
The Office Deployment Tool is a command-line utility that allows you to download and deploy specific versions of Microsoft Office. This bypasses the standard update channels and forces Outlook to revert to your preferred build.
Look up the specific version number of the earlier Outlook 2016 build you wish to revert to from Microsoft's official Office release notes.
Download the ODT from the official Microsoft Download Center and extract the files to a local folder on your computer.
Open the extracted config.xml file using Notepad. Modify the file to include the TargetVersion attribute matching your desired earlier build number.
Open Command Prompt as an administrator, use the 'cd' command to navigate to your ODT folder, and execute the command 'setup.exe /configure config.xml' to begin the rollback.
Run the Office Repair Tool
Before attempting a full rollback, try running the built-in repair tool to resolve missing contact display errors and minor syncing glitches.
Troubleshoot Unexpected Outgoing Messages
If Outlook is sending more messages than you composed, the rollback might not fix it. You need to investigate potential sync or add-in issues.
Try WPS Office as a Lightweight Alternative
If forced Microsoft Office updates are disrupting your workflow and causing interface issues, consider switching to WPS Office. It provides a familiar, easy-to-use interface, requires fewer system resources, and gives you complete control over your workspace without disruptive automatic updates.
- 1. Download the installer: Visit the official WPS website and click 'Download WPS Office Free'.
- 2. Install the software: Run the downloaded executable file and follow the straightforward on-screen instructions.
- 3. Open your existing files: Launch WPS Office and seamlessly open your existing .docx, .xlsx, or .pptx files to continue working.
Frequently Asked Questions
How do I stop Outlook 2016 from automatically updating in the future?
To prevent future automatic updates, open Outlook, click on 'File', select 'Office Account', click on 'Update Options' next to Office Updates, and choose 'Disable Updates' from the drop-down menu.
Will reverting Outlook 2016 to an older version delete my emails?
No, reverting the application version using the Office Deployment Tool typically leaves your Outlook Data Files (.pst and .ost) intact. However, it is always highly recommended to back up these files before making major system changes.
Why is Outlook showing that it's sending messages I didn't write?
This can happen due to stuck read receipts hidden in your Outbox, a misbehaving third-party add-in, or potentially a malware infection. Running an antivirus scan and starting Outlook in Safe Mode can help identify the root cause.
