Answer 1

Hi. Thank you for your question and reaching out. I’d be more than happy to help you with your query.

According to this article https://learn.microsoft.com/en-us/powershell/exchange/connect-to-scc-powershell?view=exchange-ps

The requirements for installing and using the module are described in Install and maintain the Exchange Online PowerShell module.

After you connect, the cmdlets and parameters that you have or don't have access to is controlled by role-based access control (RBAC).

For more information about it, please see the link that I have provided above.

Hi,

Did you open PS with admin elevated access? Also try to flush DNS on the system, seems like some kind of network connectivity issue.

Try the listed steps here invalidshellid-error-in-rps.md

Hope this helps.

Hi @Glenn Maxwell

Here is a link about this issue: How do you know you've connected successfully?
Please refer to this part:

You might fail to connect if your client IP address changes during the connection request. This can happen if your organization uses a source network address translation (SNAT) pool that contains multiple IP addresses. The connection error looks like this:

The request for the Windows Remote Shell with ShellId <ID> failed because the shell was not found on the server. Possible causes are: the specified ShellId is incorrect or the shell no longer exists on the server. Provide the correct ShellId or create a new shell and retry the operation.

To fix the issue, use an SNAT pool that contains a single IP address, or force the use of a specific IP address for connections to the Security & Compliance PowerShell endpoint.

I think you may have to create a
secure credential object SecureCreds credential = new PSCredential(username, password);
And then use basic authentication.
