Connect Claude & ChatGPT to Microsoft Outlook

Ask your AI what is waiting in your inbox, what is on your calendar this week, or to answer an email for you. It searches and reads email, replies and forwards, drafts and sends new messages and moves mail between folders. It also creates and updates calendar events, answers invitations, finds meeting times and keeps your contacts up to date.

In the Microsoft Entra admin center open App registrations > New registration, choose the account types you need and add the Web redirect URI https://heymyapps.com/oauth/callback. Under Certificates & secrets create a new client secret and copy its Value. Under API permissions add the delegated Microsoft Graph permissions Mail.ReadWrite, Mail.Send, Calendars.ReadWrite, Contacts.ReadWrite and MailboxSettings.ReadWrite.

Questions

What can the AI do in Microsoft Outlook?

It can search and read email, list folders and attachments, create drafts, send email, reply, reply all, forward, move, update and delete messages. It can list, create, update and delete calendar events, accept or decline invitations and find meeting times. It can also list, read, create and update contacts.

Does the AI see my Microsoft Outlook credentials?

No. Your client secret and the access from your Microsoft sign-in are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start with search and read only. Sent email and replies cannot be recalled, and new or deleted meetings notify attendees, so those tools can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

Microsoft Outlook connects with OAuth, and OAuth connections need the HeyMyApps Pro plan or above. HeyMyApps also has a free plan with no credit card, but it does not include this connection. Paid plans bill per completed task. You also need your own Microsoft 365 or Outlook.com account.

Does it work with a personal Outlook.com account?

Yes, if you choose account types that include personal Microsoft accounts when you register the app in Microsoft Entra. The connection uses your own mailbox, so it works for both work or school accounts and personal accounts. In a company tenant, an administrator may need to approve the permissions.
