Question details

Users need to resolve an issue where a shared SharePoint calendar displays different event times for different users, despite everyone having the same time zone configured.

Product: Microsoft SharePoint
Device & OS: not provided
Scenario: Coordinating schedules and viewing shared events in a SharePoint organizational calendar.
Observed behavior: Calendar events are displayed at varying times for different users even though all users have their SharePoint calendar time-zone setting configured identically to UTC+08:00.

Before you start

Verify that the local operating system time and time zone settings on each user's computer match the UTC+08:00 setting in SharePoint to rule out local device discrepancies.

Solution 1Recommended

Test the Calendar in Incognito or InPrivate Browsing Mode

Using a private browsing window forces a fresh session and helps rule out outdated browser cache or corrupted cookies that might be altering the displayed time.

Browsers often cache session data to speed up loading times. If a previous time zone session is stuck in the cache, the calendar may display incorrect times despite backend settings being correct.

Open a Private Window

Launch Google Chrome and press Ctrl+Shift+N, or launch Microsoft Edge and press Ctrl+Shift+N to open an Incognito or InPrivate window.

Sign In to Microsoft 365

Navigate to your SharePoint site URL and log in again with your Microsoft 365 credentials.

Verify Calendar Times

Open the affected shared calendar and check if the event times now display correctly for your UTC+08:00 time zone.

Clear Browser Cache: If the times appear correctly in private mode, clearing your browser's cache and cookies in the standard window will permanently resolve the issue.

Solution 2

Escalate to a Microsoft 365 Administrator

If clearing the session data does not fix the discrepancy, the issue may stem from a backend synchronization error requiring official Microsoft support.

Frequently Asked Questions

Why do SharePoint calendar events show in the wrong time zone?

This usually happens due to a mismatch between the SharePoint site's regional settings, the user's personal Microsoft 365 profile time zone preferences, local computer time settings, or stale browser cache.

How do I change my personal time zone settings in Microsoft 365?

Click your profile picture in the top right corner of the Microsoft 365 portal, select 'View account', navigate to 'Settings & Privacy', and update your 'Time zone' under the Language and region settings.

How can an administrator check the regional settings of a SharePoint site?

Site owners or admins can check regional settings by clicking the gear icon (Settings), selecting 'Site information', then 'View all site settings', and clicking 'Regional settings' under the Site Administration section.

Does clearing browser cache permanently fix SharePoint display issues?

Yes, if the issue is caused by corrupted session cookies or outdated cached data, clearing the browser cache forces SharePoint to pull fresh time zone data from the server, resolving the display anomalies.
