Does Send Email convert automatically?

Yes. It becomes an HTTP Request to Microsoft Graph /me/sendMail with your n8n Microsoft Outlook OAuth2 credential; recipients, CC, BCC, subject and HTML or text body are kept.

Is there an Outlook trigger in n8n?

Yes. The Microsoft Outlook Trigger has one event, Message Received, with filters.

How do I work with a shared mailbox?

Turn on Use Shared Inbox in the Microsoft Outlook OAuth2 credential and enter the mailbox's user principal name.

Can I use app-only auth?

Yes, with node v2 and a Microsoft Entra service principal. n8n recommends restricting it with an Exchange Online application access policy, because app permissions otherwise cover every mailbox.

Pipedream Microsoft Outlook steps in n8n

Updated 2026-10-21 · 3 min read · n8n: Microsoft Outlook (Native n8n node)

Outlook in Pipedream (the app is called Microsoft Outlook Email) sends notifications, files incoming mail and saves attachments. n8n has a native Microsoft Outlook node and a Microsoft Outlook Trigger, and the converter turns Send Email into a working Graph call.

The n8n side

Microsoft Outlook node (n8n-nodes-base.microsoftOutlook):

Resource	Operations
Message	Delete, Get, Get Many, Move, Reply, Send, Send and Wait for Response, Update
Message Attachment	Add, Download, Get, Get Many
Draft	Create, Delete, Get, Send, Update
Folder	Create, Delete, Get, Get Many, Update
Folder Message	Get Many
Calendar, Event, Contact	Create, Delete, Get, Get Many, Update

Microsoft Outlook Trigger: event Message Received, with filters such as folder, sender, read status and attachments. It polls on an interval you set.

What maps where

Pipedream (app `microsoft_outlook`)	In n8n	Status
Send Email	HTTP Request `POST /me/sendMail` (to, cc, bcc, subject, contentType, content, saveToSentItems)	automatic
Create Draft Email, Create Draft Reply	Draft → Create / Message → Reply (save as draft)	manual
Download Attachment	Message Attachment → Download	manual
Add Label to Email (categories), Move	Message → Update / Move	manual
Create Contact, Find Contacts	Contact → Create / Get Many	manual
New Email Event (Instant), New Attachment Received (Instant)	Microsoft Outlook Trigger, Message Received (+ has-attachments filter), polling	manual
New Email in Shared Folder Event	Trigger or Folder Message → Get Many on the shared mailbox	manual
New Contact Event	Schedule Trigger + Contact → Get Many	manual

Credentials

Three options in n8n:

Microsoft Outlook OAuth2 (default). On n8n Cloud, "Connect my account".
Microsoft OAuth2 (generic Graph): grant Mail.ReadWrite, Mail.Send, Calendars.ReadWrite, Contacts.ReadWrite.
Microsoft Entra Service Principal (app-only, node v2).

Self-hosted: register an app in Microsoft Entra, platform Web with n8n's redirect URL, include offline_access, then paste client ID and secret. Government and China tenants need the matching Graph base URL in the credential.

Typical migration: invoices from email to storage

Pipedream: New Attachment Received → code step (save to S3). n8n: Microsoft Outlook Trigger (Message Received, has attachments) → Message Attachment → Download → AWS S3 → Upload. The attachment travels as binary data, so no /tmp handling.

Typical migration: notification email

Pipedream: Schedule → Postgres query → Send Email. n8n after conversion: Schedule Trigger → Postgres (automatic) → Code (gather) → HTTP Request (Graph sendMail). One Outlook credential, done.

Pitfalls

Polling instead of push. Pipedream's instant sources relied on Graph subscriptions, which expire after at most 10,080 minutes (under 7 days), or 1,440 minutes with resource data, and must be renewed. The n8n trigger polls instead: nothing to renew, but up to one poll interval of delay. Do not port code that created subscriptions by hand.
Shared mailboxes need the credential's Use Shared Inbox option and Mail.Read.Shared / Mail.Send.Shared style permissions.
App-only access applies to all mailboxes unless you restrict it with an application access policy.
Personal vs work accounts. If the Entra app is single-tenant, personal Outlook.com accounts cannot connect.
