ms_outlook_attachment: Outlook mail attachment

In Azure/Microsoft365R: Interface to the 'Microsoft 365' Suite of Cloud Services

Outlook mail attachment

Description

Class representing an attachment in Outlook.

Format

An R6 object of class ms_outlook_attachment, inheriting from ms_outlook_object, which in turn inherits from ms_object.

Fields

• token: The token used to authenticate with the Graph host.

• tenant: The Azure Active Directory tenant for the email account.

• type: always "attachment" for an attachment.

• properties: The attachment properties (metadata).

Methods

• new(...): Initialize a new object. Do not call this directly; see 'Initialization' below.

• delete(confirm=TRUE): Delete this attachment. By default, ask for confirmation first.

• update(...): Update the attachment's properties (metadata) in Microsoft Graph.

• do_operation(...): Carry out an arbitrary operation on the attachment.

• sync_fields(): Synchronise the R object with the attachment metadata in Microsoft Graph. This method does not transfer the attachment content for a file attachment.

• download(dest, overwrite): For a file attachment, downloads the content to a file. The default destination filename is the name of the attachment.

Initialization

Creating new objects of this class should be done via the the get_attachment(), list_attachments() or create_attachment() methods ms_outlook_email class. Calling the new() method for this class only constructs the R object; it does not call the Microsoft Graph API to retrieve or create the actual attachment.

In general, you should not need to interact directly with this class, as the ms_outlook_email class exposes convenience methods for working with attachments. The only exception is to download an attachment in a reliable way (not involving the attachment name); see the example below.
