I discovered the issue. The env var does not appear to work for this variable. Instead, the following works:

```  variables:
    AZURE_STORAGE_CONTAINER: $(Pulumi.StorageContainer)

  steps:
  - task: Pulumi@1
    inputs:
      azureSubscription: &lt;service principal connection&gt;
      command: 'up'
      cwd: '$(ProjectDirectory)/'
      stack: '${{ parameters.stack }}'
      args: '--yes'
    env:
      PULUMI_CONFIG_PASSPHRASE: $(Pulumi.Passphrase)
      AZURE_STORAGE_ACCOUNT: $(Pulumi.StorageAccount)
      AZURE_STORAGE_KEY: $(Pulumi.StorageKey)```
