Date format in Teams on the search results

Hi Ralph_Wijbenga,

you can change the date format from the Windows settings by opening Windows Settings, clicking on Time & language, clicking on Date & time, and choosing the date/time format.

Teams should respect your date/time format from the Windows settings.

If you’ve already set your regional settings correctly in Teams, SharePoint, and your operating system, but Teams is still displaying dates in the US format, it might be a limitation of Teams.

If this is the case, I would recommend submitting feedback through the Teams app by selecting Help in the bottom lower-left of Teams and then choosing to Suggest a feature or Give Feedback to let Microsoft know about this issue.
