To find the Outlook 365 calendar ID, you need to access the calendar's properties. Here's how:
- Right-click on the calendar for which you need the ID.
- Select "Properties" from the context menu.
- In the Properties dialog box, go to the "General" tab.
- Locate the "Calendar ID" section. The alphanumeric string displayed there is the unique Calendar ID for that calendar.
This ID can be used for various integrations, API calls, or when you need to specifically identify a calendar programmatically.
