O365 source

Hi,
I am trying to create a source for o365. I have tested exchange and azureAD and get the same results. I authenticate successfully but when I try to save the source I get;
Unable to create a Source. Unauthorized operation. Please check if you have the appropriate admin account settings on your account.
I have checked and have Global admin on the tenant. I have added organisation management on exchange roles. I am able to hawk logs with the account and can connect via powershell.
Not sure what to try next.
