But what if you are behind a proxy and are unable to connect?
Chances are that there is one process that goes directly to the internet:
When trying to connect you get the error below:
This PowerShell module allows you to connect to Exchange Online service. To connect, use: Connect-EXOPSSession -UserPrincipalName your UPN To get additional information, use: Get-Help Connect-EXOPSSession PS C:\Users\> Connect-EXOPSSession -UserPrincipalName username@yourtenant.onmicrosoft.com New-ExoPSSession : Connecting to remote server outlook.office365.com failed with the following error message : WinRM ca nnot complete the operation.

We have to force all traffic through the proxy, the easiest way to do this is with netsh:
Check current settings for the PowerShell session:
netsh winhttp show proxy
Current WinHTTP proxy settings:
Direct access (no proxy server).
Set the proxy server:
netsh winhttp set proxy proxy.domain.lan:8080
Current WinHTTP proxy settings:
Proxy Server(s) : proxy.domain.lan:8080
Bypass List : (none)
Reset to no proxy server settings:
netsh winhttp reset proxy
Current WinHTTP proxy settings:
Direct access (no proxy server).
