"You've hit your usage limit. To get more access now, send a request to your admin or try again at {Mon Dth, YYYY H:MM PM}."

This is the workspace variant of the Codex usage-limit message. Instead of "upgrade" it tells you to ask your admin, because on Business and Team plans seat allowances and workspace spend caps are set in the workspace, not by the member. The "try again at" time is when the exhausted window refreshes.

All three source reports were filed on 2026-04-06 by Business seats (openai/codex issues #16917, #16909, #16906). In #16917 the reporter had used nothing in the previous 30 days, the web app showed "You've reached your workspace spend cap", and /status printed "limits: data not available yet", which points at a workspace cap or a limit-data sync problem rather than a genuinely empty window.

OpenAI's help center says Codex, ChatGPT Work and Workspace Agents "use a shared allowance and credit pool when those features are available on your plan"; on a workspace plan that pool and any spend cap are what the admin controls.

Your own window: when the message is about a genuine window, the "try again at" time is the refresh time for your seat; a date days away is the weekly limit. Paste it into the window tracker for a countdown. When it is a workspace spend cap, the time in the message may not help: access returns when the admin raises the cap or the workspace period rolls over.

Account-wide resets: OpenAI occasionally announces a reset for everyone, applied automatically to "the usage limits covered by the announcement". Whether a specific workspace cap is covered is stated only in that announcement. The board row above shows the last reset on record; the Codex history page lists every announcement with its original post.
