How to implement a shared company calendar in MS Outlook?

Question

System administration

There is Exchange Online, user accounts, etc. Each user has the ability to start meetings for themselves and invite others. You need to monitor the meetings of all people in the company. There are more than 100 people, so opening all calendars for access is not an option. As a solution, we made the meeting room calendar, but meetings may not take place there, so they will not fall into the general display scheme.
How to make a general company calendar so that all meetings are registered in it by default, and not done in the personal calendars of employees?

Answer 1

Some kind of such logic should work in theory:
1.Create a user who has "always accept invitations" enabled in the calendar settings. There was also something with a busy status, but I haven’t held exchange in my hands for a long time.
2. Create a transport rule - if a calendar event is sent to anyone - it is copied to this user (I remind you that rooms are essentially the same contacts, you can keep a room if item 1. works)
3. Possible problem : I don't remember if sending an invitation to oneself goes through a transport rule (creating an event for one person. For example, like a vacation and the like) - you might not be able to catch this.
But in general, for any organization, only the administrative component works well in this case, the order: 'create all meetings in the calendar "All company meetings"'

Answer 2

It is most likely not possible to do this in the standard way.
You can script in Powershell either the issuance of rights, or export-import from calendars.
