Get all AA/CQ with Resource Accounts

Hello JFM_12,
The supported approach is to query AAs and CQs separately and then join them with resource accounts via application instance associations.

At a high level, the process is:

1. Use Get-CsAutoAttendant and Get-CsCallQueue to retrieve all AAs and CQs.
2. Use Get-CsOnlineApplicationInstance to retrieve all resource accounts.
3. For each AA and CQ, check whether a resource account is associated by matching the ConfigurationId using Get-CsOnlineApplicationInstanceAssociation.
4. If no associated resource account is found, treat that entry as missing a resource account.
   
   

Microsoft documents that each Auto Attendant or Call Queue is expected to have a resource account, but the platform does allow misconfigured or orphaned objects to exist (for example, after deletions or failed provisioning), which is why this audit is useful.

As reference:

• Resource accounts are required and managed separately:

• Associations between resource accounts and AAs/CQs are handled via Online Application Instance associations:

If you want to avoid writing custom logic from scratch, community tools such as TeamsAACQTools already implement this correlation logic and can export AA/CQ configurations alongside their resource accounts:
