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.” > **[Core Infrastructure and Security Blog](https://techcommunity.microsoft.com/t5/core-infrastructure-and-security/bg-p/CoreInfrastructureandSecurityBlog)** Looks like Exchange does not work with those accounts. ---
