Microsoft 365

Send and read Outlook mail, put files in OneDrive, add calendar events and To Do tasks, all from one Microsoft 365 node.

Pick a saved connection in the Credential field, or create one from there. It signs in with an OAuth2.

What it does

The Microsoft 365 node works on four kinds of things (Resource), each with its own Operation:

• Mail (Outlook): send an email, save one as a draft, list your latest messages, or get one message.
• File (OneDrive): upload text as a file, list the files at the top of your OneDrive, or create a sharing link for a file or folder.
• Calendar (Outlook calendar): create an event, or list events.
• To Do: create a task, or list the tasks of a list.

Everything happens in the signed-in account (your own mailbox, drive, calendar and lists). When you fill Source URL, the node adds a Source: line with that link to the end of the email body, event description or task note, so you can keep track of the page it came from.

Mail → List and Calendar → List return 10 items by default (up to 100). File → Upload sends the text in File content as a single upload, which suits files up to about 4 MB. When List ID is empty, To Do uses your default task list.

When to use it

• Email yourself or a colleague a summary built by an AI node, with the source page linked.
• Save a report as a text or CSV file in OneDrive, then share a view link to it.
• Add a meeting or deadline you found on a page to your Outlook calendar.
• Turn a page into a To Do task, “read later” style.

If you use Google’s apps, see Gmail, Google Drive and Google Calendar.

Need an operation that isn't listed? — 

Call the Microsoft 365 API yourself with the HTTP Request node, and pick the same connection in its Credential field.

Use HTTP Request →

• To and Attendees take one email address per entry.
• Body type decides whether Body is read as plain text or as HTML. It is plain text when not set.
• File path is relative to the top of your OneDrive, with folders separated by /, for example Reports/daily.csv. An existing file at that path is replaced.
• Content type is the file’s type, such as text/csv or application/json. It is text/plain when empty.
• Start (date-time) and End (date-time) take a date and time without an offset, like 2026-09-10T09:00:00. They are read in Time Zone, which is UTC when empty, so set it (for example Europe/Paris) to avoid events at the wrong hour.
• Link type is View and Link scope is Anyone when not set. Your organization may not allow Anyone links; use Organization then.
• Message ID, Item ID and List ID come from the id field of a list operation’s output.

Outputs

• Output

• Mail → Send returns success: true once Outlook accepts the email. The email is also saved in Sent Items.
• Mail → Draft, Mail → Get, Calendar → Create event and To Do → Create task return the created or fetched item as Microsoft sends it, with its id.
• Mail → List returns one item per message with id, subject, from, receivedDateTime, webLink and bodyPreview.
• File → List, Calendar → List and To Do → List return one item per file, event or task.
• File → Upload returns the file’s details, including its id, which you can pass to File → Get link.
• File → Get link returns the sharing link; the address is in link.webUrl.

Dependencies and credentials

• Credential (connection, OAuth2): required. See Create a connection.

The credential is a Microsoft sign-in (OAuth2). You first register a small app in the Azure portal, as a public client with no secret, and paste its Application (client) ID into the credential. Give it these delegated Microsoft Graph permissions: offline_access, Mail.ReadWrite, Mail.Send, Files.ReadWrite, Calendars.ReadWrite and Tasks.ReadWrite. Then sign in with your Microsoft account and accept the permissions.

Follow Create your OAuth client for the step-by-step registration, then Create a credential. The sign-in renews itself, so you do not need to sign in again for each run.

Example workflow

1. A Context Menu trigger adds “Remind me” to the right-click menu on any page.
2. Get Page Metadata reads the page’s title and url.
3. Microsoft 365, To Do → Create task, with Title Read: {{ $input.title }} and Source URL {{ $input.url }}. Leave List ID empty to use your default list.
4. Browser Notification confirms the task was added.

Common issues

• “Microsoft Graph Error: access denied — your organization’s admin may have blocked this app…”. Your organization blocks the app, or one of the permissions needs an admin’s consent. Ask your Microsoft 365 admin to approve the app, or use an account that allows it.
• “Missing credential”. No credential is selected. Pick or create one in Credential.
• “Microsoft Graph Error: no To Do lists found for this account”. List ID is empty and the account has no To Do list. Open Microsoft To Do once to create one, or set List ID.
• The event is at the wrong time. Time Zone is empty, so the times were read as UTC. Set your time zone.
• The run is blocked in the web app. Microsoft 365 runs through the browser extension. Install the extension and allow Microsoft 365 for this workflow when asked, or run the workflow from the extension. See Running extension-only integrations in the web app.
