Hello OpenAI Community,
I am facing a critical issue with my ChatGPT Business workspace. For more than 24 hours, I have been unable to invite any new members, even though my subscription and billing are active and seats are available.
Every invitation fails immediately with this message:
Unable to invite user due to an error.
The failed invitation does not appear under Workspace Settings → Members → Invites/Pending Invites.
Workspace and billing status
- ChatGPT Business subscription is active.
- Total seats: 4
- Seats currently in use: 2
- Available seats: 2
- Recent invoices show Paid.
- A valid payment method is available.
- I have Owner/Admin access to the workspace.
What I have already tested
I have tried all of the following:
- Inviting a single member manually.
- Inviting multiple members through CSV.
- Trying multiple different email addresses.
- Using the
Memberrole. - Using CSV with an explicit
ChatGPTseat type. - Using CSV with a
Codexseat type. - Chrome normal mode and Incognito mode.
- Another browser.
- VPN and proxy disabled.
- Different internet/network connection.
- Confirmed SSO is not enforced.
- Confirmed SCIM is not enabled.
- Confirmed external-domain invitations are allowed.
- Confirmed there are no pending invitations for the affected email addresses.
The issue occurs with every email address I try.
CSV formats tested
I tested the standard format:
email,role
user @ example .com,member
I also tested an explicit seat type:
email,role,seat type
user@ example. com,member,ChatGPT
The CSV is accepted and processed, but every member is shown as failed.
Network/API details
I captured the invitation request through Chrome DevTools.
Request method:
POST
Status code:
200 OK
Sanitized request payload:
{
"email_addresses": [
"user @ example .com"
],
"resend_emails": true,
"role": "standard-user",
"seat_type": "default"
}
Response body:
{
"account_invites": [],
"errored_emails": [
{
"email_address": "user @ example.com",
"error": "Unable to invite user due to an error."
}
]
}
The request technically returns HTTP 200 OK, but the application-level response contains an empty account_invites array and places the email inside errored_emails.
This means the request reaches the backend, but the invitation is not created.

Support status
I have already contacted OpenAI Support and provided the billing details, screenshots, request payload, response body, request ID and timestamp. The issue has been escalated to a support specialist, but I urgently need a workaround because my business operations are currently blocked.
Has anyone experienced the same issue recently?
Specifically:
- Was this caused by a workspace-level restriction or backend account state?
- Did OpenAI Support need to reset or repair the workspace invitation configuration?
- Is there any temporary workaround to add members while the support case is under investigation?
- Could a usage-credit limit incorrectly affect standard Business member invitations, even when paid seats are available?
Any guidance from the community or OpenAI team would be greatly appreciated.
Thank you.
