GoKawiilOpenAI confirmed today that ChatGPT and Codex users can now add multiple Gmail and Google Cal accounts. Here are the details.
‘Add your second (or third!) account’

For many users who rely on ChatGPT’s plugins for those platforms, there has been one limitation until now. Each plugin could only be connected to a single Google account, making it harder to use ChatGPT Codex across separate personal and work inboxes or calendars.
Today, as confirmed by OpenAI DX engineer Gabriel Chua, the company rolled out multi-account support for Gmail, Google Calendar, and Google Contacts.

To add another account, users can open the Plugins section in the sidebar, find Gmail, Google Calendar, or Google Contacts, and click the gear icon for a plugin they have already connected. From there, they can add a second or third account and complete the usual Google authorization process.
