# List mail folders

`listMailFolders` lists either the mailbox's top-level folders or the direct
children of a selected folder.

```ts automations/list-outlook-folders.automation.ts theme={null}
import { automation } from "automate.ax"
import { listMailFolders } from "automate.ax/outlook"

export default automation("List Outlook folders", () => {
  listMailFolders({ parentFolder: "Archive", includeHidden: false, limit: 100 })
})
```

## Output

Returns folders with `folderId`, `displayName`, `childFolderCount`,
`totalItemCount`, `unreadItemCount`, and `isHidden`. Numeric counts default to
zero and `isHidden` to false if Graph omits them.

Folder names match case-insensitively across the full hierarchy. Use a path such
as `Projects/Launch` or an ID when duplicate names would be ambiguous.
