Microsoft is moving the MT service from Microsoft DataMarket to Azure portal by the 30 April 2017.
Due to this change, there will be temporarily two ways how to set your Microsoft Translator or Microsoft Translator Hub MT Engine in Memsource. You can use Microsoft DataMarket (Client ID and Client Secret) or Azure portal (Azure Key).
Please note that only one of the credential can be used.
See more details in our Machine Translation User manual.
