# Delete Queue

| Step Details |
| --- |
| **Introduced in Version** | 3.0.0 |

The **Delete Queue** step is used to remove a previously created queue.

### Prerequisites

- This step requires the [MSMQ](https://documentation.decisions.com/docs/msmq) module to be [installed](https://documentation.decisions.com/docs/installing-modules-decisions) before it will be available in the toolbox.
- A [dependency](https://documentation.decisions.com/docs/project-dependencies) must be created after installing the module in order for the the steps to be properly used.

## Common Errors

### Failed to Delete Queue By Path

If the inputted queue path does not lead to an existing queue, the step will cause an error. To correct this, change the inputted Path Queue to reflect the path of the queue intended to delete.

#### Exception Message:
