If you have multiple Azure subscriptions linked to the account that you use to login – the operations in Azure PowerShell are executed against the “current subscription”. You can use the Get-AzureSubscription PowerShell cmdlet to see all of the subscriptions and also which is the “current” subscription. During a PowerShell session, you will need to use the Select-AzureSubscription cmdlet to choose which subscription data set is used by other Azure cmdlets with the following syntax "Select-AzureSubscription -name "NameOfYourSubscription".
