Overview
Outlook on Microsoft 365 brings mailbox email into the same system as your pipeline. For enterprises already on Entra ID, conditional access and admin consent flows are part of a successful rollout. Pair this with Outlook Calendar sync so meetings and mail stay aligned on each account.
What data is involved
- Email threads and metadata attached to CRM leads, contacts, and optionally opportunities.
- Microsoft identity (work or school account); shared mailboxes where supported.
- Complements but is distinct from Teams notifications—Teams is channel alerts; Outlook is mailbox content.
