OutlookSearch your Outlook email and calendar in Glean
Set up the Outlook connector once and Glean builds a permission-aware index of your organization's email and calendar, and can also fetch live results. Access is read-only and scoped to each user's own Outlook permissions.
Choose your path
Glean connects to Outlook with a read-only, certificate-based Microsoft Entra app. Which path is yours depends on your Glean deployment, not on when you personally connect Outlook.
New setup
You're on a new Glean deployment, created on or after August 14th, 2026. Register the single-tenant Azure app, grant the read-only Microsoft Graph permissions, upload the certificate, and Glean builds a permission-aware index of your email and calendar.
Previous setup
You're on an existing Glean deployment. Even if you're connecting Outlook for the first time, keep the setup you have to manage permissions, crawl restrictions, and indexing scope.
