How can I backup my Windows 10 outlook.live calendar? I have Windows 10. I use the free version of the outlook.live calendar. I need to export the calendar to a pst to back it up. I am retired and only need access to my calendar for appointments and past meetings. So I don't need Microsoft 365 but it says I have to subscribe to MS 365 in order to export anything. I tried to switch to the classic version to export for free, but the classic version doesn't exist anymore. How can I backup my calendar?

    If you are unable to use Classic Outlook to export your outlook.live calendar as a PST, an alternative is to export it as an ICS file.

    Using New Outlook for Windows

    View -> View Settings -> Calendar -> Shared calendars - Publish a calendar.
    Select one of (or the only) Calendar for your account.

    User's image

    Select permissions = Can view all details.
    [Publish]

    User's image

    You should now see two long URLs. Click the "ICS" one and -> Download

    User's image

    This should open a browser window and download and ICS file to your PC.

    This ICS file is a snapshot of your current Calendar and can be imported into New Outlook or Classic Outlook.

    Hi. I'm Brian and I'll try to help.

    You can download and install classic Outlook from the Microsoft store.
