Manage Room Mailbox by using PowerShell

In the current article, we will review how to use PowerShell commands for managing Room mailbox in Exchange Online environment.

Resource Mailbox is a special type or a Mailbox that uses for the management of meeting Rooms and Equipment.
The Resource Mailbox doesn’t require a license.
Management of Resource Mailbox could be implemented by using one of the following options:

Self-management – the Resource Mailbox will be configured for automation of accepting meeting requests (or decline meeting request if a former meeting request was already set).
Resource Mailbox delegate – The delegate is the person that will accept the meeting requests and approve or decline the meeting requests.

The term “resource Mailbox” includes two types of Mailboxes – Room Mailbox and Equipment Mailbox.

There is a small difference between the two types of the resource mailbox but the use, and the purpose are quite similar (most of the examples will relate to room Mailbox).

A Little confession: I must admit that it wasn’t easy to give up the strong need for naming these articles: Get a Room!
(But I know that this is a “serious” WebSite and, for this reason, I use a formal name).
