gMSAs , WinRM and Exchange scheduled scripts

Greetings,
I am trying to convert my scheduled scripts to using Managed Service Accounts.
My gMSA works fine with scripts that do AD stuff.
When I attach the gMSA to a script that runs Exchange cmdlets using the pssession route, I get credential errors.
Is there something I am missing or cant you use gMSAs with WinRM and Exchange cmdlets?
Thanks
David

“MSA’s are not supported for applications like Exchange or SQL.”

Looks like Exchange does not work with those accounts.
