An error has occurred. {1}{0} when trying to import Exchange Appointments

One of my favorite features in Project Operations stopped working suddenly. When I am at time entries, and select Import -> Exchange Appointments, I started getting this error An error has occurred. {1}{0}. Behavior is same for other users as well. I work fine few months ago. As the error is quite non-descriptive, this is what I am able to get from the network-tab of my browser. There is full log file attached

{
    "error": {
        "code": "0x80040216",
        "message": "Could not retrieve appointments because:\r\nThe request failed. The request was aborted: The request was canceled.\r\nThe request was aborted: The request was canceled.\r\nAccess token could not be obtained from: https://accounts.accesscontrol.windows.net/tokens/OAuth/2 for resource: XXXX/outlook.office365.com@XXXXXX. nToken request failed.\r\nThe remote server returned an error: (401) Unauthorized.\r\n"
    }
}

    Hi,
     
    I see this in the error message, so unauthorized. Check with your administrator.
