Trigger

When a new email arrives (V3) — Office 365 Outlook

Set the folder to Inbox. Add subject/sender filters as needed.

Step 1 — Export email (V2)

Export email (V2) — Office 365 Outlook

• Message Id: Message Id (dynamic value from trigger)

This action returns the raw MIME content of the email (RFC-2822 format, compatible with .eml).

Step 2 — Create file

Create file — OneDrive for Business

• Folder Path: /Outlook/inbox
• File Name: <Subject>-<Received Time>.eml — compose using dynamic values from the trigger, sanitizing characters not allowed in file names
• File Content: Body (dynamic value from the Export email (V2) step)

The file is created in OneDrive and, on next refresh_index call or server restart, it will be picked up automatically by eml-mcp tagged as inbox.

Duplicate the inbox flow and change only two values:

• Trigger folder: Sent Items
• Folder Path (Create file step): /Outlook/outbox

eml-mcp will tag these emails as outbox.
