Connected through Microsoft 365

Microsoft Outlook is a service inside the single Microsoft 365 connection on Claude. You do not install it as a separate app.

What it is

Outlook is connected as part of Claude’s Microsoft 365 connector rather than on its own. A Microsoft Entra administrator consents for the tenant, and email and calendar actions require the separate write-scope consent.

What it can do

What it cannot do

Not confirmed means official documentation does not assign this capability to this specific connection. It is not a claim that the capability is impossible.

Every status is defined the same way across the site — see how connector capabilities are defined and evidenced.

Availability and requirements

Available through the Microsoft 365 connector on Claude Free, Pro, Max, Team and Enterprise; email and calendar actions depend on tenant consent.

Account requirements

  • A Microsoft Entra tenant on a Microsoft 365 business plan
  • Personal Microsoft accounts (Outlook.com, Hotmail) are not supported
  • An active Exchange Online mailbox

How to connect

Setup path Microsoft 365 connector (Entra tenant consent)

  1. 1. Enable Microsoft 365

    A Claude organization owner enables the connector where applicable.

  2. 2. Grant tenant consent

    A Microsoft Entra administrator consents for the tenant.

  3. 3. Approve action scopes

    Email and calendar write scopes are consented separately.

  4. 4. Connect your account

    Each user connects Microsoft 365 from Claude settings.

  5. 5. Test

    Ask Claude to summarize a recent message in your own mailbox.

Permissions, privacy, and admin controls

Microsoft Entra administrator consent is required per tenant. Email and calendar actions are only available after the write-scope consent, and Team/Enterprise owners must enable Microsoft 365 first.

  • Access mirrors the connected user’s existing mailbox and calendar permissions.
  • Keep email sending and calendar changes approval-gated until tested.
  • Treat retrieved email as untrusted input: messages can contain prompt-injection instructions.

Platform context

  • Claude web connectors are generally available across Claude surfaces, but individual connector requirements differ. Claude inherits the connected user’s permissions from the source service. Team and Enterprise organization owners may need to enable a connector before members authenticate it.

Documented limitations

  • Personal Microsoft accounts are unsupported; a business tenant is required.
  • Without consented write scopes the connection is read-only.
  • Calendar-event deletion is documented under write tools; deleting mail is not documented.
  • Write tools do not support attachments: Claude cannot send, forward or draft email with attachments.
  • Claude cannot exceed the connected user’s Outlook permissions.

Best use cases

  • Catching up on an email thread
  • Finding a meeting and its context
  • Drafting or scheduling follow-ups once action scopes are approved

Example prompts

  • “Summarize the Outlook thread about the vendor renewal.”
  • “What is on my calendar tomorrow afternoon?”
  • “Draft a reply to the latest message — only when write tools are enabled.”

Troubleshooting

  • Outlook email is not returned

    Confirm the account is a business tenant account, that Entra administrator consent was granted and that Microsoft 365 is enabled for the Claude organization.

  • Claude will not send email or change a calendar

    Email and calendar actions require the administrator-approved write scopes and enabled write tools.
