Could not upload to the storage location Dynamics 365 for finance and operations.

I was experimenting with Office integration in Dynamics 365 for finance and operations. On Create Excel worksheet. I got following error

Could not upload to the storage location: Unable to connect to the remote server.

Later I found that on my onbox, Azure Emulator was not running.

So I did

1. On OneBox VM, run command prompt as administrator.
2. Navigate to “C:\Program Files (x86)\Microsoft SDKs\Azure\Storage Emulator\”
3. Run “AzureStorageEmulator.exe start”

After running that service, Download options perfectly worked
