I know proxmox service is very new & need some improvements, but I saw below problems.

1- Some items in service properties page is unclear & require more explanation or documentation.

2- When I add proxmox service & go to Virtual Servers Proxmox page of my users to create a new VM, I get this error:

Error reading organization mailboxes
Exception has been thrown by the target of an invocation.

& in event viewer, the real problem is:

Exception message: Could not create type ‘SolidCP.EnterpriseServer.esVirtualizationServerProxmox’.
