I'm relatively new to UTM, Powershell and Office 365. My goal this morning was to use PowerShell to connect to my brand new Office 365 tenant and learn how to manage it, but I was very frustrated by my inability to connect.
When running this line:
Connect-MsolService -Credential $credential
I would get this error:
There was no endpoint listening at https://provisioningapi.microsoftonline.com
Checking my Sophos logs, I saw 407 authentication errors. My connections had no user name attached.
What got things working for me was to configure PowerShell to use proxy authentication. I entered this line (replacing proxy.mydomain.net with my actual UTM proxy address:
Invoke-WebRequest -Proxy http://proxy.mydomain.net:8080 -ProxyUseDefaultCredentials http://example.org
After that, PowerShell continued to use "my" proxy settings, and I was able to connect to Microsoft Office365.
