Exchange Online - Calendar not showing title of the meeting

Issue:

When we create a meeting and add a room resource the calendar fails to show the subject of the meeting. Instead the Room shows the organizer

As shown here. The title of the meeting is IT and the Room shows Todd Quest

Cause:

In Office 365 & Microsoft Exchange, by default, your resource mailbox won’t show your Meeting Subject. Instead, it replaces this with your organizer’s name. This occurs for privacy reasons, but it’s only the default. It occurs because AddOrganizerToSubject and DeleteSubject attributes are set to True. Mentioned below is an article on this issue and its resolution.

Resolution:

Note that for Exchange Online/Office 365 you need to connect through elevated Powershell with a Global Admin credentials, then connect to exchange online as per article,
