Check if there is an existing OABVirtualDirectory on any of the servers: get-oabvirtualdirectory [this command can take up to half an hour to complete, depending on the size and scope of your domain]
Remove the existing OAB virtual directory with the following command: Remove-OABvirtualdirectory -identity “<server name>\OAB (Default Web Site)”
New OAB command: New-OABVirtualDirectory -RequireSSL $true -ExternalURL “https://<full DNS name>/OAB”
All the VSS (Volume Shadow Copy) writers, including the “Microsoft Exchange Writer”, should be present with running the following command from an elevated command Prompt:

Modify the “Disable Exchange Writer” registry key to a value of 0 and restart the “Exchange Information Store” service.
With application-aware processing enabled in a Veeam backup job for a Hyper-V virtual server:
|Guest processing skipped (check guest OS VSS state and hypervisor integration components version)
Failed to create snapshot (Microsoft Software Shadow Copy provider 1.0) (mode: Crash consistent) Details: Guest processing skipped (check guest OS VSS state and hypervisor integration components version)
Error: Guest processing skipped (check guest OS VSS state and hypervisor integration components version)
The reason is:
VM CAPTION IS #BACKUP USING SAVED STATE#. BACKUP WITH IN-GUEST VSS CURRENTLY IS NOT POSSIBLE
It seems that the Hyper-V integration components did not specify to use the system provider within this virtual server. I forced using the ‘Microsoft Software Shadow Copy provider’ inside the effected guest by adding this DWORD value.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\BackupRestore\UseMicrosoftProvider = 1
