Exchange 2016 – configure InternetWebProxy and InternetWebProxyBypassList

If an Exchange 2016 server is behind a web proxy it is possible to configure this using the Set-ExchangeServer PowerShell cmdlet with the InternetWebProxy and InternetWebProxyBypassList parameters.  Here is an example:

Set-ExchangeServer -Identity MailServer01 -InternetWebProxy "http://192.168.0.254:8080"
Set-ExchangeServer -Identity MailServer01 -InternetWebProxyBypassList @("webmail.mydomain.com","autodiscover.mydomain.com")

To view the settings for all Exchange servers in the organisation use the Get-ExchangeServer cmdlet:

Get-ExchangeServer | Format-List Name,InternetWebProxy,InternetWebProxyBypassList
