The owner sends you a workspace invite, you click it, and the page says This invite is expired or This invitation is no longer valid. Sometimes it dumps you on a generic ChatGPT sign-up page with no workspace name at all. The owner swears the link was made five minutes ago.
Fastest fix (works in ~70% of cases): open the invite in a fresh private/incognito window and sign in with the exact email the invite was sent to. Most “expired” errors are really wrong-account or wrong-active-workspace errors in disguise. If that fails, have the owner open Workspace settings > Members, find your pending invite, click the ••• menu and choose Resend — a freshly issued email invite is valid for 7 days.
Naming note (as of June 2026): OpenAI renamed the ChatGPT Team plan to ChatGPT Business on August 29, 2025. It is the same product and workspace; menus now say “Business” but most people still search “Team.” Everything below applies to both names. The web app also moved to chatgpt.com (old chat.openai.com links redirect).

Diagnose before you regenerate. Match your symptom to the most likely cause.
| What you see | Most likely cause | Who checks | Fix section |
|---|---|---|---|
| ”Expired” right after a fresh send | Wrong active account / workspace | You | Step 1-2 |
| Opens then redirects to plain ChatGPT | Signed in as a non-invited email | You | Step 1 |
| ”No longer valid” on an old email | Link past 7-day TTL | Owner | Step 3 |
| ”Invalid” with a personal email | Domain restriction on the workspace | Owner | Step 4 |
| Accepts then errors out | Seats full | Owner | Step 5 |
| Joins wrong workspace / can’t see it | Multiple workspaces, wrong one active | You | Step 6 |
Common causes, highest hit rate first
1. You are signed in as the wrong account
The invite was issued for you@company.com, but ChatGPT currently has you@gmail.com logged in. The platform returns a generic “invalid” rather than a clear mismatch message.
How to judge: open the invite in a private window. The flow should explicitly name (or ask for) the invited email. If it silently lands you in your personal chat, you were signed in as the wrong user.
2. The invite link aged past its 7-day TTL
Email invites are valid for 7 days from when they are sent (official OpenAI limit, as of June 2026). After that the Join link can no longer be redeemed, even if nobody used it.
How to judge: owner check — was the invite sent more than a week ago? In Workspace settings > Members, expired invites drop out of the Pending invitations list or show as no longer actionable.
3. The link was already consumed
If you opened the email invite earlier (even just to preview it) and a link-prefetch service or another browser tab “clicked” it, the token can read as used. Email invites are bound to one recipient and meant to be accepted once.
How to judge: ask the owner whether your row shows under Pending invitations (still good) or already moved to the active Members list under a session you do not recognize.
4. The workspace enforces a domain restriction
Some workspaces only admit allowed email domains (@company.com). A personal address (@gmail.com, @outlook.com) is rejected, sometimes silently.
How to judge: owner — check Workspace settings for an allowed-domains / verified-domain rule under Members or Identity & access. If a list is set, your email’s domain must be on it.
5. The seat count is full
Owners and admins can over-invite relative to paid seats. The link opens, but accepting it errors because there is no seat.
How to judge: owner — Workspace settings > Billing (or the seats panel). 5/5 used means no room. Note: since April 2, 2026 a workspace has two seat types, standard ChatGPT seats (fixed monthly) and Codex seats (usage-based); make sure the standard seat pool has room.
6. You have multiple workspaces and the wrong one is active
A single ChatGPT account can belong to more than one workspace (personal + one or more Business workspaces). If the wrong one is active, you may not see the new workspace even though you joined it — this looks like the invite “did nothing.”
How to judge: click your profile menu (bottom-left, below chat history). The Workspaces section lists every workspace you belong to. If the new one is there, you are in — just switch to it.
Before you start
- Get the exact invite link the owner sent (the real URL from the email, not a screenshot).
- Confirm which email the owner invited. Ask if unsure.
- Decide which OpenAI account will be the long-term member.
- Close other ChatGPT tabs so a stale session does not interfere.
Information to collect
- Full invite URL.
- The email the invite was issued to.
- The email you are currently signed into ChatGPT with.
- When the invite was sent (owner side).
- A screenshot of the exact error page.
- Whether you have ever been in this workspace before.
- Your timezone (helps support correlate logs).
Step-by-step fix
Step 1: Open the link in a private window
Close all ChatGPT tabs, open a private/incognito window, and paste the invite URL. This removes “already signed in as the wrong user” as a variable. The flow should now show exactly which email it expects.
Step 2: Sign in or sign up with the exact invited email
When prompted, use the email the owner invited. If you have never used that address on OpenAI, Sign up — it creates a fresh account that joins the workspace immediately. If you already have an account on that email, Log in. Do not “log in with another email just to look” — that re-introduces the mismatch from cause 1.
Step 3: Ask the owner to resend the invite
If the link is genuinely past its 7-day TTL or consumed, the owner should resend rather than create a brand-new entry:
Workspace settings > Members > Pending invitations >
[your row] > ••• menu > Resend inviteIf your row is gone, they re-add you with Invite member > enter your email > Send. A fresh email invite is good for another 7 days. Tell them which inbox to send to so it matches the email you will sign in with.
Step 4: Verify the workspace allows your domain
If you keep getting “invalid,” it may be a domain rule. Ask the owner:
Can you check Workspace settings > Members (or Identity & access)
for an allowed-domains / verified-domain rule? My email is
you@example.com. If there's a restriction, please add my domain
or invite me as an individual-email exception.Owners can add per-email exceptions for outside collaborators.
Step 5: Check seat capacity
Have the owner check Workspace settings > Billing (seats panel). If full, they either add a standard seat (takes effect immediately, prorated) or remove an inactive member, then resend your invite. Confirm the standard ChatGPT seat pool has room — Codex seats (usage-based, added April 2, 2026) are separate and do not grant standard workspace access.
Step 6: Switch workspaces (or leave the wrong one)
If you actually joined but cannot see the workspace, switch to it: profile menu (bottom-left) > Workspaces > pick the new workspace. If you need to leave an old workspace first:
Profile menu > select the old workspace > Workspace settings >
Members > ••• next to your name > Leave workspace
> confirm with your emailLeaving removes your access to that workspace’s chats, so export anything you need first.
Step 7: Contact OpenAI support if the link genuinely refuses
If a fresh invite still fails, the owner (or you) can open a ticket at help.openai.com:
Subject: ChatGPT Business invite shows invalid despite being freshly sent
Workspace name: Acme Inc
Owner email: owner@acme.com
Invited email: you@acme.com
Invite sent at: 2026-06-14 10:00 PT
Error shown: "This invitation is no longer valid."
Please confirm the invite state on the backend and reissue.Owners get priority routing, so have the owner file it if you can.
How to confirm it’s fixed
chatgpt.comshows the workspace name in the top-left after you sign in.- Your profile menu > Workspaces lists the new workspace and lets you switch to it.
- The model picker shows your workspace’s models (Business tier matches Plus plus admin-controlled extras).
- The owner sees you as Active (not Pending) in
Workspace settings > Members.
Long-term prevention
- Owners: use email invites in
Members, not forwarded URLs. They are bound to one recipient and easy to resend. - Build a habit: invite, accept, and verify within the 7-day window; re-issue if it lapses.
- Tell new joiners exactly which inbox the invite will hit — kills the “wrong email” round-trip.
- Owners: pre-check the allowed-domains list before inviting outside collaborators.
- Keep one workspace as each person’s primary so they do not get lost in the workspace switcher.
Common pitfalls
- Forwarding the invite email. The Join link is bound to the recipient address; a colleague clicking it fails.
- Link-preview prefetch. Some corporate mail or chat tools pre-open links, which can consume a single-use token before you click.
- Using an old URL after a re-issue. If the owner cancelled and re-sent, use the newest email only.
- Signing in with the wrong email “just to peek,” then clicking the invite — your logged-in identity now conflicts with the invite.
- Assuming you can decline and re-issue endlessly. Resends to the same recipient can be rate-limited.
FAQ
- How long is a ChatGPT Team/Business invite valid? Email invites expire 7 days after they are sent (as of June 2026). Once expired, the Join link cannot be redeemed; the owner just resends.
- Is ChatGPT Team the same as ChatGPT Business? Yes. OpenAI renamed the plan to ChatGPT Business on August 29, 2025; it is the same workspace product, same data, only the label changed.
- Why does the invite open and then redirect to plain ChatGPT? You are signed into a non-invited account. Open the link in incognito and sign in with the invited email.
- Can the owner move my old seat to a new email? Not directly. They remove the old member and invite the new email; the new account joins fresh.
- Do I keep my personal Plus if I join a Business workspace? Your account can hold both, but you are paying twice for overlapping features — most people cancel personal Plus, since Business covers equivalent chat features. Personal chats stay in your personal workspace; they do not move into Business.
- Why can’t I see the workspace even though I accepted? You likely have the wrong workspace active. Switch via profile menu > Workspaces.
