Does Microsoft Outlook connect to ChatGPT?

Yes, but Outlook Email and Outlook Calendar are two separate official ChatGPT apps, grouped here as "Outlook" for this catalog. Both support search and read of mail and calendar content; write, send, and delete actions are documented specifically for shared or delegated mailboxes and calendars, not for every connected mailbox or calendar.

Connected through Outlook Email and Outlook Calendar apps in ChatGPT

Microsoft Outlook is a service inside the single Outlook Email and Outlook Calendar apps in ChatGPT connection on ChatGPT. You do not install it as a separate app.

What it is

OpenAI publishes Outlook Email and Outlook Calendar as two distinct apps in ChatGPT; this record covers both because Connector Scout tracks Outlook as a single application family. Verified capabilities include searching and reading email, and searching and reading calendar events and availability, plus drafting email content. Where actions and the relevant Microsoft permissions are enabled, OpenAI's March 13 and April 8, 2026 release notes and its help documentation describe shared and delegated mailbox workflows — marking messages read or unread, moving messages, and sending plain-text mail from or on behalf of a shared mailbox — and shared calendar workflows that create, update, RSVP to, cancel, and delete events, plus add small attachments. Contact and contact-folder creation and updates are also documented. Every one of these write, send, and delete behaviors is scoped in OpenAI's sources to shared or delegated mailboxes and calendars; no source documents the same actions for a user's own primary mailbox or calendar, so this record does not extend them there.

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

Availability depends on which of the two apps (Outlook Email, Outlook Calendar) is enabled, plan, workspace, role, surface, model, and region; shared/delegated workflows additionally require the relevant Microsoft permissions and action settings to be enabled.

Account requirements

  • An eligible Microsoft work or school account
  • Outlook Email and/or Outlook Calendar app authorization
  • Microsoft-side delegation or shared-mailbox/calendar permissions for shared workflows
  • Any required workspace approval

How to connect

Setup path Workspace app enablement + Microsoft organizational sign-in, per app

  1. 1. Ask for enablement

    Ask the ChatGPT workspace admin to enable Outlook Email and/or Outlook Calendar.

  2. 2. Connect the account

    Connect the organizational Microsoft account to the relevant app.

  3. 3. Grant delegated/shared access

    For shared mailbox or shared calendar workflows, confirm Microsoft-side delegation or shared permissions are in place.

  4. 4. Review action settings

    Review which mail and calendar actions ChatGPT is permitted to take before relying on send, update, or delete.

  5. 5. Test

    Test with a message or event the user can already access.

Permissions, privacy, and admin controls

Workspace admin controls apply to both apps; shared and delegated mailbox and calendar workflows additionally require the associated Microsoft permissions to be granted and ChatGPT action controls to be enabled.

  • App permissions do not grant Outlook access beyond what the connected Microsoft account, and any delegated or shared-mailbox permission, already allows.
  • Sending, moving, or deleting messages and events changes real Outlook content; keep shared/delegated workflows approval-gated until tested.

Platform context

  • OpenAI’s Plugin Directory is now the main discovery surface, while apps remain the integrations that connect ChatGPT to external data and actions. App capabilities and availability can vary by app, plan, workspace, role, surface, model, and region. Business workspace admins can manage apps; apps are enabled by default for Business and disabled by default for Enterprise/Edu. Enterprise/Edu can use role-based access controls. ChatGPT permissions do not give an app new provider permissions; they govern when ChatGPT asks before using access already granted. Voice mode does not currently support apps.

Documented limitations

  • Outlook Email and Outlook Calendar are separate apps; enabling one does not enable the other.
  • Write, send, and delete actions are documented only for shared or delegated mailboxes and calendars — not for a user's own primary mailbox or calendar.
  • No sync/index mode is documented for either app.
  • Attachments added to shared calendar events are documented as small only.
  • Sending is documented as plain-text mail, not rich formatting.

Best use cases

  • Searching and summarizing email threads
  • Checking calendar availability before proposing meeting times
  • Drafting a reply for review before sending
  • Managing a shared team mailbox's read/unread state and message routing
  • Updating or canceling events on a shared team calendar

Example prompts

  • “Find recent emails from our vendor about the contract renewal.”
  • “Check my calendar for open slots next Tuesday afternoon.”
  • “Draft a reply to this email confirming the meeting time.”
  • “Mark the newest messages in the support shared mailbox as read and move the resolved ones to Archive.”
  • “Cancel Thursday's stand-up on the team shared calendar and notify attendees.”

Troubleshooting

  • Sending or deleting from a mailbox is unavailable

    Confirm the mailbox is a shared or delegated mailbox with the required Microsoft permission, and that the ChatGPT action setting for that behavior is enabled; these actions are not documented for a personal primary mailbox.

  • Calendar content is missing or out of date

    Confirm the correct app (Outlook Calendar, not Outlook Email) is enabled and connected, and that the account has read access to the calendar in question.
