Capabilities and Permissions
What it can do
Searches and retrieves messages from the signed-in user’s mailbox (read-only), including metadata such as subject, sender, recipients, timestamps, and plain-text body.
Supports keyword and structured searches such as from:, subject:, and date filters.
Fetch endpoints provide full message text for results returned by search.
Permission requested (scopes)
Note: The app requires the following scopes to be reviewed and approved by your Microsoft Entra admin. If the scopes are not approved by your Entra admin, you may see an error when trying to connect the app within ChatGPT.
Approval of scopes does not immediately make all actions available to users. Admins and owners must still review app actions in Workspace settings > Apps for the app. In Action control, admins can choose how the app's current actions are handled by allowing all actions, allowing only read actions, or selecting a custom set of actions.
If admins select Custom, they can also choose how actions added later are handled by selecting Enable all new actions, Only enable new read actions, or Disable new actions. If admins select Disable new actions, they must review and enable new actions before users can use them. After admins allow additional actions, users may need to reconnect the app to use them.

Known limitations
Search precision follows Microsoft Graph indexing latency — very recent emails may take a short time to appear.
Some broad or long-running requests (for example, summarizing all emails over an extended period of time) may exceed service limits enforced by Microsoft. In these cases, ChatGPT may return an error.
Workaround: Narrowing the date range or breaking the request into smaller queries often resolves the issue.
Your workspace owner or admin may restrict which Outlook accounts you can connect, to an approved set of domains.
