Fix Microsoft Planner Regional Settings Reverting to US
Question details
The user needs a solution to stop Microsoft Planner from resetting its time zone and language settings to United States defaults.

- Product
- Microsoft Planner
- Device & OS
- not provided
- Scenario
- Updating regional and language preferences for Microsoft 365 applications.
- Observed behavior
- Planner fails to retain custom regional settings and automatically reverts back to the US region after the user attempts to save changes.
Ensure you are using a Microsoft account with the necessary permissions to modify Microsoft 365 profile settings, and check if an IT administrator has enforced organization-wide regional policies.
Verify Settings and Re-authenticate Your Account
Confirm your master Microsoft account settings are correct and force a session refresh in Planner to resolve potential sync glitches.
Microsoft Planner inherits its regional data from your main Microsoft profile. Sometimes, a simple re-authentication can force the application to fetch your updated time zone and language data.
Go to myaccount.microsoft.com/settingsandprivacy/language in your web browser and log in with your credentials.
Verify that your preferred language, display language, and regional formats are correctly selected and saved in the master profile.
Click on your profile picture in the top right corner and select 'Sign out'. Ensure you are signed out across all active Microsoft 365 browser tabs.
Log back into Microsoft Planner. Check the settings menu to see if the correct region is now successfully applied and retained.

Frequently Asked Questions
Why do my Microsoft 365 settings keep defaulting to the US?
This is typically caused by a background synchronization bug where a specific application, like Planner, fails to fetch your updated regional data from your central Microsoft profile, forcing a fallback to the default United States settings.
Will changing my computer's local time zone fix the Planner issue?
No, Microsoft Planner relies entirely on your Microsoft 365 cloud account preferences. Changing your local Windows or Mac time zone will not override the web application's regional sync bug.
Where can I check if this regional settings bug has been patched by Microsoft?
You can track the status of known issues and upcoming bug fixes by visiting the official Microsoft 365 Roadmap online, or by monitoring the specific ticket you upvoted on the Microsoft Feedback Portal.
