A Windows Proxy performs all necessary PowerShell cmdlet calls against the Office 365 cloud AND the server monitoring on-premises infrastructure (required in hybrid infrastructures). The virtual appliance and the simulation bots do not necessarily need the Windows Proxy. 
However, to get the most out of panagenda OfficeExpert, we highly recommend to deploy a Windows Proxy with the following requirements:

  • min. Windows Server2016 Standard
  • Hosts have to be member of your Active Directory Domain
  • All required ports have to be opened (see Network and Firewall - Requirements)
  • Internet access is needed to access the cloud environment
