Question details
The user wants to adjust the Microsoft AutoUpdate schedule on a Mac to prevent frequent update prompts from interrupting their daily workflow.

- Product
- Microsoft Office / Microsoft AutoUpdate
- Device & OS
- macOS
- Scenario
- Trying to work continuously without being interrupted by persistent Microsoft application update reminders.
- Observed behavior
- Microsoft AutoUpdate launches frequently during working hours based on a preset interval, asking users to close files and install updates, which disrupts their work.
Ensure you are logged in to your Mac with an administrator account, as modifying system update schedules or property list (.plist) files requires admin privileges.
Switch AutoUpdate to Manual Mode
The easiest and safest way to prevent interruptions during working hours is to disable automatic updates and check for them manually when it is convenient.
Launch any Microsoft Office application installed on your Mac, such as Word, Excel, or PowerPoint.
Click on 'Help' in the top Apple menu bar and select 'Check for Updates' from the dropdown menu to open the Microsoft AutoUpdate tool.
Uncheck the box labeled 'Automatically keep Microsoft Apps up to date' or click 'Advanced' to toggle off automatic downloads and installs.
To keep your software secure, remember to reopen this tool manually during the evening or non-working hours to install any pending updates.

Modify the StartInterval Value Using Terminal
Advanced users can modify the com.microsoft.update.agent.plist file via Terminal to change how frequently the agent checks for updates in the background.

Frequently Asked Questions
Will Microsoft AutoUpdate automatically close my files and quit the app?
No. Microsoft 365 applications will generally not close, save your work automatically, or force an installation without your interaction. However, the persistent pop-up reminders will continue until you manually close your files and proceed with the update.
Why do I keep getting update reminders at different times of the day?
Microsoft AutoUpdate launches whenever a new update becomes available on their servers. If you ignore an update notification without completing the installation, the tool will continue to prompt you periodically to ensure the application stays secure.
Why can't I edit the com.microsoft.update.agent.plist file directly in Finder?
Property list (.plist) files located in the system or library folders are protected by built-in macOS permissions to prevent accidental system changes. You typically need to use Terminal with 'sudo' commands or a dedicated plist editor with administrator privileges to successfully modify them.
What happens if I set the update option to Auto?
If you set it to Auto, Microsoft AutoUpdate will download the updates in the background. It will then display a message prompting you to quit the active Microsoft applications so it can apply the updates, but it will not abruptly force-quit your unsaved work.
