Get all AA/CQ with Resource Accounts

Hello JFM_12,

To identify Auto Attendants (AA) and Call Queues (CQ) that do not have Resource Accounts assigned, you must correlate voice apps, resource accounts, and their associations using Microsoft Teams PowerShell. This involves retrieving all Auto Attendants, Call Queues, and Resource Accounts, mapping them using Get-CsOnlineApplicationInstanceAssociation, and exporting the results to identify any missing assignments. Since neither Microsoft Graph nor the Teams Admin Center currently provides this relationship in bulk, PowerShell remains the only supported method for performing this type of tenant-wide audit.

You must use:

Get-CsOnlineApplicationInstanceAssociation
