100-word summary

OpenAI quietly published documentation showing ChatGPT can now read, send, and organize emails from shared Outlook mailboxes, plus manage shared calendars. The catch? Your admin must approve ten specific Microsoft permissions first, and you need to tell ChatGPT the exact email address of the mailbox owner in every prompt. The integration runs through Microsoft Graph APIs, meaning very recent emails might not appear immediately due to indexing delays. Calendar event descriptions stay read-only for shared calendars. Translation: support@ or sales@ could finally get automated triage, but IT needs to greenlight it first. Shared inbox chaos might actually become manageable.
