Properties of room mailboxes

February 22, 2021 Views: 3737

The script generates and sends a report on properties of room mailboxes located in a specific AD domain.

Note: The script will export only properties of mailboxes hosted in Exchange 2007. To be able to run the script, you need to install Microsoft Exchange Server 2007 Management Tools on the computer where Adaxes service is installed.

To schedule the report, create a scheduled task configured for the Domain-DNS object type that runs the script and assign it over the domain where the room mailboxes are located. To add the script to a scheduled task, use the Run a program or PowerShell script action.


  • $to - Specifies a comma separated list of recipients of the report.
  • $subject - Specifies the email message subject.
  • $reportHeader - Specifies the email message header.
  • $tableHeader - Specifies the header for a table containing properties of the mailboxes.
  • $reportFooter - Specifies the email message footer.
  • $calendarProperties - Specifies the properties of the mailbox calendar to include in the report.
