Mozilla thunderbird will not display my @hotmail.com calendar

more options

I have installed Mozilla Thunderbird as my email browser and can see and send emails using Mozilla Thunderbird. However I can not see my calendar so installed the lightning add on which failed to help, also installed the google add on which failed to help. I have my @hotmail calendar on another pc and ipad and work and sync fine so how do I get it to work with Mozilla Thunderbird. Any help would be gratefully appreciated.

Unfortunately, Microsoft has not provided a way to be able to synchronize back and forth your online Outlook.com/Hotmail with any other calendar.

You can "publish" your Outlook.com calendar and have Lightning in Thunderbird subscribed to it. It will be read only in Thunderbird though. You will be able to see your calendar events, but not edit or change them.

Or you can "publish" your Outlook.com calendar and save it as it is at the moment, to your computer, then import the calendar into Thunderbird. Then you will be able to edit and change the calendar, but the changes will not show up on your Outlook.com calendar.

2. Click the gear icon in the top right of the webpage.

3. Select "Options".

5. Select the calendar you want.

6. Under "Show availability, titles, and locations", click the "Create" Button.

A. If you want to save the calendar to your computer, to import into Thunderbird, then right-click the link for the ICS file and choose "Save Link As", and save the file on your computer.
