Add virtual desktop to existing RDS VDI collection

Hi there,

A customer has removed a virtual machine out from the VDI Collection. The VM is still available on Hyper-V. For some reason I'm not able to re-add the VM back to the pool. I tried PoSh with the following command:

Add-RDVirtualDesktopToCollection -CollectionName "Name" -VirtualDesktopName "V10015" -ConnectionBroker "Broker FQDN"

The output is:

Add-RDVirtualDesktopToCollection : Cannot add an existing virtual desktop to a managed virtual desktop collection.  Instead, specify how many virtual desktops to add for each server by using the VirtualDesktopAllocation parameter.

Does anyoune have a short feedback on that?

Cheers,
Al
