# Get Email Attachments by Id

| Step Details |
| --- |
| **Introduced in Version** | 9.26.0 |
| **Last Modified in Version** | 9.26.0 |
| **Location** | Integration > Microsoft365 > Exchange > Email |

The **Get Email Attachments by Id** step retrieves all attachments associated with a Microsoft365 email using the email's Message Id. This allows flows to access and process attachment content from Exchange emails.

### Prerequisites

- This step requires that the [Microsoft 365 Exchange](https://documentation.decisions.com/docs/microsoft365-exchange) module be [installed](https://documentation.decisions.com/docs/installing-modules-decisions) before it becomes available in the toolbox.
- A [dependency](https://documentation.decisions.com/docs/project-dependencies) must be created after installing the module for the steps to function correctly.

## Common Errors

### Attachments Not Returned

If no attachments are returned, the Message Id may not correspond to an email with attachments, or the email may not be accessible. To resolve this, verify that the email contains attachments and that the correct Message Id and User Identifier are provided.

#### Exception Message:

```csharp
DecisionsFramework.BusinessRuleException: No attachments found or unable to retrieve attachments for the specified Message Id.
```

### The Request Was Unsuccessful

If the OAuth token is invalid or expired, the request to Microsoft Exchange will fail. To resolve this, ensure that a valid OAuth token is configured and that the user has appropriate permissions.

#### Exception Message:

```csharp
DecisionsFramework.BusinessRuleException: The request was unsuccessful.
---> System.Net.Http.HttpRequestException: Response status code does not indicate success: 401 (Unauthorized).
```
