Codex and ChatGPT now connect multiple Gmail and Calendar accounts
Link several Gmail, Calendar and Contacts accounts at once and keep work and personal in separate conversations — actions included, not just reads.

It reaches Codex, not just ChatGPT
The rollout covers Codex as well as ChatGPT, so the coding agent can read and take actions across more than one Google account in a single session — useful when your work identity owns the calendar and repos while a personal account holds the rest. OpenAI shipped it August 28.
One conversation per identity, running in parallel
You can keep one chat acting through a personal Gmail while another runs on a work account, instead of disconnecting and reconnecting a single login every time. That kills the constant account-swapping when an assistant has to straddle both inboxes, calendars and contacts.
The catch: admin and workspace controls still gate it
Connected accounts stay bound by their own app permissions and workspace controls, so an org admin can still block the connection. OpenAI lists availability on Plus, Pro, Business and Enterprise across web, desktop, iOS and Android.
