Configure Veeam Backup for Microsoft Office 365 to use an HTTP proxy
Challenge
Solution
To make Veeam Backup for Microsoft Office 365 use an HTTP proxy, the following must be done:
- Using the netsh command, a system proxy must be configured in order for Exchange Online PowerShell to work properly. Please start an elevated cmd.exe and input:
Netsh Winhttp Set proxy <proxyFQDNorIP>
- Ensure that no Backup or Restore jobs are running, then stop both the Veeam Backup for Microsoft Office 365 Service and the Veeam Backup Proxy for Microsoft Office 365 Service
- Navigate to %ProgramData%\Veeam\Backup365
- Edit Config.xml, adding <Ews UseSystemProxy="True" /> under <Veeam>, but above <Archiver>
- Do the same thing with Proxy.xml
- Navigate to the Veeam Backup for Microsoft Office 365 installation path (by default %ProgramFiles%\Veeam\Backup365), edit the file Veeam.Archiver.Service.exe.config,and add the following lines under <configuration>:
<system.net> <defaultProxy> <proxy proxyaddress="http://yourproxyFQDNorIP:port" usesystemdefault="true" /> </defaultProxy> </system.net>
- And the same thing for Veeam.Archiver.Proxy.exe.config
- Pay attention to proxy address format – ‘http://yourproxyFQDNorIP’ and ‘port’ are mandatory, otherwise you will see errors like this one
