Connect-IPPSSession with Modern Auth

Question

Hello,

I am able to connect to Exchange Online with modern auth, but when I try Connect-IPPSSession, I get this message about basic auth needing to be enabled:

PS C:\Windows> Connect-IPPSSession -UserPrincipalName xxxx@xxxxxxxxxxxxx .com
WARNING: Please note that you can only use above 9 new EXO cmdlets (the one with -EXO naming pattern).You can't use other cmdlets as we couldn't establish a Remote PowerShell session
as basic auth is disabled in your client machine. To enable Basic Auth, please check instruction here

• throw $_.Exception;

I am running Exchange Online 2.0.5. Has anyone else run into this? Can you use modern auth with Connect-IPPSSession?

Thanks

Answer 1

Basic auth is disabled client-side in this case, on the WinRM settings. So you can just enable it there. Microsoft has not yet updated the Connect-IPPSSession to get rid of the WinRM dependencies, this should happen in the next module version. Btw, V3 is out now: https://learn.microsoft.com/en-us/powershell/exchange/exchange-online-powershell-v2?view=exchange-ps#updates-for-version-300-the-exo-v3-module
