Hi @Vincent ,
Welcome to our forum.
Does anyone might know something about this so that I can merge the calendar appointments with my other calendars?
As I know, in the point of Outlook client, we could merge other calendars to a calendar via export a .pst file from a calendar and import it to another calendar like below:
- Export a .pst file from calendar A: File>Open&Export>Import/Export>Export to a file>Outlook Data File(.pst)>choose the calendar you need to export
- Import your file to calendar B: File>Open&Export>Import/Export>Import from another program or file>Outlook Data File(.pst)>Browse your calendar data file>choose Do not import duplicates
So that we have merged the items in calendar A to calendar B, and based on my tests, other users in your organization could see the busy status of these importing items, which seems to could meet your need.
However, it's obvious that this method couldn't achieve a real-time synchronization, it could only merge your original items from a calendar to another. If you indeed would like to sync all your calendars, there seems to be no option to satisfy it directly in Outlook, and you may need the help of other macros or third-party synchronization tools to achieve it.
