Importing/Exporting Outlook Calendar Events as Timing Tasks

Simply copy one of the following script into a new "Script Editor" document, select "JavaScript" as the script's language, and press run (see this article for more detailed instructions).
After pasting them, consider saving the scripts to disk for future re-use. You could even save them to iCloud Drive (or e.g. Dropbox or Google Drive) to have them available on all your Macs.
Feel free to customize the scripts for your use cases.

Note: We do not take responsibility for any data loss incurred by running these scripts.
Make sure to back up your data (e.g. by copying the directories mentioned here to a different location) before running these scripts.

In case Timing seems to use the wrong Outlook calendar for importing/exporting, you might have multiple calendars with the same name.
In that case, try replacing [0] at the end of calendarApp.calendars.whose({ name: calendarName })[0] with e.g. [1] or [2] to select a different calendar with the same name.
