Having dificulties connecting to the AIP Service via Powershell

I am attempting to enable email encryption within my organization. According to the Setup process in https://video2.skills-academy.com/en-us/microsoft-365/compliance/set-up-new-message-encryption-capabilities?view=o365-worldwide the first step is to verify that ARM is enabled. The service does not appear to be active for my tenant.
Running the GetIRMConfiguration shows AzureRMSLicensingEnabled is set to False, so i have set this to True, however, Test-IRMConfiguration dispalys a failure.
The next step in the documentation asks that i Connect to the AIPService moudule, i have run the Import-Module AIPService which is successfull but the Connect-AIPService fails with:
Connect-AipService: The attempt to connect to the Azure Information Protection service failed. Verify that the credentials you are using are correct and try again. If you have continued problems, see http://go.microsoft.com/fwlink/?LinkId=251909.
The correlation ID is 9de07c3e-f436-442c-b645-5d34f056bf2d. Please note and provide this value if asked by support for it.
I have confirmed the credentials for the account i am using and that the account is setup as a global administrator and the account is licensed with E5 as are all other active users.

I would appreciate any assistance in resolving the issue.

Thanks
