OutlookInstall

Summary

Reply to a message and include its existing recipients. Choose the current or another mailbox, provide the message ID and reply body, then send the reply immediately or save it as a draft; optional binary attachments and inline images are supported.

Inputs

• Mailbox — Choose the current mailbox (default) or another mailbox. For another mailbox, provide its email address.
• Other Mailbox Email (required) — Email address of the other mailbox; shown and required when Mailbox is set to Other Mailbox.
• Message ID (required) — ID of the message to reply to.
• Use Immutable ID — Set to true if Message ID is an immutable ID; the operation adds the Microsoft Graph Prefer header for immutable IDs. Defaults to false.
• Comment (required) — Reply body content.
• Body Type — Format of the reply body: HTML (default) or plain text.
• Save to Draft — Save the reply as a draft instead of sending it immediately. Defaults to false.
• Add Attachment — Attach a binary file from the incoming item to the reply. Defaults to false.
• Binary Field Name — Name of the incoming item's binary property to attach; defaults to data and is shown when Add Attachment is enabled.
• Inline Images — For HTML replies, specify binary image fields and content IDs. Reference each image in the body with a cid: URL.
• Auto-Embed Image URLs — For HTML replies, fetch public image URLs in img tags and convert them to inline CID attachments. Defaults to false.

Output shape

A single message record.

The source routes this operation through the reply helper, using reply-all behavior and returning the Graph response as an n8n execution item. Saving as a draft changes the action to create a draft; otherwise the reply is sent.
