Align Time Zone Settings Across Outlook and SharePoint
The most common cause of calendar time discrepancies is a mismatch between the individual's Outlook time zone and the SharePoint site's regional settings.
When a SharePoint calendar is added to Microsoft Teams as an app or website tab, it inherits the regional configuration of the underlying SharePoint site. If this configuration differs from the end-user's local Outlook settings, the synchronized calendar will display conflicting appointment times.
In Microsoft Outlook, navigate to 'File' > 'Options' > 'Calendar'. Scroll down to the 'Time Zones' section and note your currently selected time zone.
Log into your SharePoint site. Click the gear icon in the top right corner and go to 'Site Contents' > 'Site Settings' > 'Regional Settings'.
In the Regional Settings menu, ensure the selected time zone matches the exact time zone you verified in Outlook. Apply and save the changes.
Once both locations are set to the identical time zone, refresh your Microsoft Teams application or reconnect the calendar tab to ensure it fetches the updated regional data.

Frequently Asked Questions
Why does my calendar show different times in Microsoft Teams compared to Outlook?
When a SharePoint calendar is added to a Teams channel as a website or app tab, it relies on the SharePoint site's regional time zone settings rather than your local Outlook configuration. If these two settings do not match, the event times will display differently.
Can team members view a shared SharePoint calendar in Teams in their own local time zones?
Currently, a SharePoint calendar embedded directly into a Teams channel tab displays the time zone configured in the SharePoint site's Regional Settings for all users. For personalized time zones, users must sync the SharePoint calendar to their personal Outlook desktop application.
Do I need administrator rights to change the SharePoint time zone?
Yes, modifying the Regional Settings of a SharePoint site typically requires Site Owner or Site Administrator permissions. If you do not see the 'Site Settings' option, you will need to request that your IT administrator update the time zone.
