M365 - on-premise AccessNode - using web proxy ?

Question

Hi guys,is there a way to use a web proxy to backup Exchange/Sharepoint/Onedrive Online ?since only https connections are used, it should be possible to forward backup requests to a web proxy instead of place am AccessNode in the DMZ.I cannot find any hints for that in BOLBRKlaus

Hello @johanningkI believe this is possible with an internet proxy.Note this must be run as systemYou would not configure anything different in commvault but we must set the server to use the proxy so when we run the powershell commands the proxy is used:Downloaded PSToolsPsExec - Windows Sysinternals | Microsoft DocsOpen command prompt as adminChanged the directory to where the PSTools is extracted to and ran the following command:PSExec.exe -i -s -d cmd.exeChanged the directory to c:\program Files\Internet Explorer\ and openInternet explorerChanged the configuration on the Internet explorer to run using the Proxy server specified Destination ip and port.This sets the proxy settings for the machines system account so that when we initiate commands as system account it has the proxy config

Hi Scott,this nearly worked.Unfortunately the IIS on the CommServe (not the CommandCenter), still tries to communicate directly with Microsoft’s login portal, when setting up the configuration.All later backup traffic was able to use the proxies.we finally had to provide direct access to the login portals for the CommServe to successfully setup the M365 backups.BRKlaus
