# Outlook - Workflow node | Docs - nodulz

Source: https://nodulz.com/docs/nodes/outlook

Language: en

Send and manage emails, folders and calendar events.

## Usage and specifics

Select a Microsoft Graph credential with resource permissions. OneDrive also accepts delegated OAuth. Triggers poll changes periodically; publish to activate them. Supply drive, site, list or user identifiers for the chosen operation.

Technical type : `outlook`. Runtime : `nodulz`.

## Credentials and prerequisites

- [Microsoft Graph](/docs/credentials) (`integration` / `microsoft_graph`). OneDrive, SharePoint and Outlook with an Entra ID application.

Create credentials in your nodulz instance’s Credentials area, then select them on the node. Availability depends on ownership and sharing. See the [credentials guide](/docs/credentials) for access and rotation.

## Initial configuration

Initial catalog configuration example, to adapt before running. Keep secrets in credentials.

```json
{
  "credentialId": "",
  "userId": "",
  "driveId": "",
  "siteId": "",
  "listId": "",
  "itemId": "root",
  "folderId": "inbox",
  "calendarId": "",
  "operation": "list_folders",
  "name": "",
  "data": "{}",
  "query": "{}",
  "content": "",
  "encoding": "base64",
  "to": "",
  "subject": "",
  "destinationId": ""
}
```

## Verification

Test with representative data. Check node output in the inspector and logs, then use editor mapping for downstream fields. A trigger test with a simulated payload does not validate external service delivery.
