    Hi,

    May I ask what version of your MacOS? You may experience Reduced Functionality mode when support for Microsoft 365 or Office apps is no longer available for older operating systems or devices. For most users, updating your OS will resolve it.

    I look forward to your response.

    Stay Safe!
