Microsoft 365 room mailboxes serve as valuable resource mailboxes connected to physical locations! To explain more clearly, a room mailbox in Office 365 is a type of resource mailbox associated with a physical location, indicating spaces like conference rooms or shared workspaces. Moreover, it is used to manage the scheduling and booking of the room for meetings and other events.
Monitoring and managing room mailboxes play a crucial role in ensuring smooth planning and allocation of meeting rooms within an organization. Therefore, Office 365 admins often require usage reports to gain valuable insights into the utilization of these rooms. As I have said, monitoring room mailboxes is imperative as it enhances user experience, optimizes resources, and helps to efficiently plan room capacities. In this regard, let’s delve into the process of generating comprehensive room mailbox usage statistics using PowerShell.
Ways to Check Office 365 Room Mailbox Usage Report
Monitoring the room mailboxes in Microsoft 365 helps admins make informed decisions and implement necessary improvements that positively impact meeting room management throughout the organization. Moreover, you can get the room mailbox usage report with the help of the following methods.
View Calendar Information of Room Mailboxes:
So, to obtain Exchange Online meeting room statistics, any user with delegate permission can access the Outlook calendar of the respective room mailbox and view the information. But it is impossible to view all the meeting room utilization reports at one time.
Get Room Mailbox Usage Using PowerShell:
You can get the room mailbox usage statistics using the “Get-MailboxStatistics“ and “Get-MgUserEvent“ cmdlets. Executing the above cmdlets can provide details like, meeting duration, meeting ID, start and end time, and some miscellaneous of the respective meetings. However, multiple formatting is typically required to obtain different report formats, which can be time-consuming!
Therefore, to overcome the limitations of Outlook calendar and PowerShell, we have prepared a PowerShell script that provides valuable insights into meeting room usage. So, let’s look into the script’s details, explore its features, and optimize your organization’s meeting room allocation like never before!
