    mfocictThank you for your update. unfortunately, for me still the same issue exist even after clearing Teams Desktop APP Cache. The weird thing: the Teams Desktop APP calendar time is wrong while the Teams mobile App time is correct !

     

    SamirAhmedis the issue fixed at your side ?

     

    Thank you

     

    Best Regards

    Update for the Teams Desktop App does work as of Saturday morning, 6 May.  For some/many users, we found we had to quit Teams, delete the cache in Teams and relaunch Teams in order for the updated calendar to show correctly.  

     

    The issues with MS Edge and the Outlook app on Android still are ongoing.
