When I tried to create Windows Server 2012 R2 VM, the deployment failed with the error message:
Error submitting the deployment request. Additional details from the underlying API that might be helpful: The template deployment 'Microsoft.WindowsServer2012R2Datacenter-201601514442' is not valid according to the validation procedure. The tracking id is '92fa161b-8bd5-4929-880e-aff52bdcb658'. See inner errors for details.
I tried a few different D and DS-series VM sizes, and tried in both East Asia and Southeastern Asia regions.
