Error since enabled "Enable application-aware processing"

[cobra]

Hello,

I use Veeam on an physical Windows Server 2008R2.
Hyper-V is running on an Windows Server 2012 Datacenter.

Since I enabled "Enable application-aware processing", the VMs cant be backuped anymore.

Our case ID: 00957830

5 of 12 VMs throw an error.

Our Exchange 2010 on an Windows Server 2008 R2:
Unable to subscribe to guest processing components: timed out waiting for Hyper-V integration components to respond
Unable to create snapshot (Microsoft Software Shadow Copy provider 1.0) (mode: Veeam application-aware processing). Details: Failed to prepare guests for volume snapshot.
Error: Failed to prepare guests for volume snapshot.

On other Windows Server 2008 R2:
Guest processing skipped (check guest OS VSS state and integration components version)
Unable to create snapshot (Microsoft Software Shadow Copy provider 1.0) (mode: Crash consistent). Details: Failed to prepare guests for volume snapshot.
