Noiz Mail Troubleshooting

This page lists every message you can meet while connecting or using Noiz Mail, grouped by where you see it, with what it means and what to do. If your message is not here, open a ticket and quote it exactly, with the name of your AI app. Never send us your password.

Last reviewed: 4 November 2026, against the live Noiz Mail connector.

On the Sign-In Page

• Symptom: “Address or password incorrect.” Use your full email address and your mail password, not your Noiz client area password. After 5 wrong attempts, sign-in pauses for up to 15 minutes. The pause applies to the address your AI app or browser connects from, so it can affect everyone on your office connection.
• Symptom: “Too many failed sign-ins.” The 15-minute pause above is in force. Wait it out; a correct password during the pause is not tried.
• Symptom: “Mail for example.com is not hosted by Noiz.” That address is not on a mail server we run. Check the address for typing mistakes. If it is correct and you host mail with us, contact us: the domain’s MX record may point elsewhere.
• Symptom: “The mail server could not be reached.” Your mail server did not answer, or its name could not be looked up. Try again in a minute, and tell us if it continues.
• Symptom: “Line 12 (name@example.com): address or password incorrect.” The password on that line of your pasted list is wrong. Nothing was connected. Fix that line and paste the whole list again; the list is cleared because it holds passwords.
• Symptom: “Line 12 (name@example.com): this mailbox is already listed with another password.” The same mailbox is in the list twice with different passwords. Remove the wrong line and paste the whole list again.
• Symptom: “Too many failed sign-ins for name@example.com (line 12).” That mailbox has had too many wrong passwords recently, from this list or elsewhere. Wait 15 minutes, or leave that line out and add the mailbox later on the manage page.
• Symptom: fewer mailboxes connected than pasted. Checking stops after 60 seconds plus 2 seconds per mailbox. Start the connection again and paste the full list, or add the rest on the manage page.
• Symptom: the page says the connection is busy or asks you to try again shortly. Your mail server has as many connector sessions open as it allows. Try again in a minute.

In Your AI App

• Symptom: the app cannot finish connecting, or returns to the sign-in page. In Claude, remove Noiz Mail and add it again, choosing Register automatically for the OAuth client; on Team or Enterprise the Owner does this under Organization settings, then Connectors, and everyone connects again. In ChatGPT, remove the plugin and add it again. In Codex, run codex mcp login mail again.
• Symptom: a Reconnect button appears, or the app asks you to sign in again. A password changed, the connection has not been used for 30 days, or it is 90 days old. Click Reconnect, or sign in again from the connector’s settings. If there is no Reconnect button, disconnect and connect again.
• Symptom: the AI says a mailbox could not be opened. That mailbox’s password changed. Enter the new password on the manage page; the other mailboxes keep working meanwhile.
• Symptom: the AI says the mail server is busy. The connector waited 30 seconds for a session on your mail server without getting one. Nothing was changed. Ask again shortly.
• Symptom: the AI says the connection is busy. Four of your calls were already running. Nothing was changed. Ask again shortly.
• Symptom: the AI cannot move mail to a folder. The folder does not exist. Noiz Mail never creates folders: make it in your mail app or webmail first, then ask again.
• Symptom: the AI cannot open an attachment. It is over 5 MB, or it is a picture, a scanned PDF or an Office file with no readable text. Open it in your mail app instead.
• Symptom: the AI says the message was sent but no copy is in Sent. The message went; saving the Sent copy failed, usually because the mailbox is full or the Sent folder is missing. Check the mailbox’s quota in your control panel.
• Symptom: the AI sent without asking you. Your app is set to “always allow” or “allow all” for this connector. Change that setting back, and tell the AI to show you each message first. See Security and Privacy.
• Symptom: ChatGPT does not use the connector for a follow-up question. ChatGPT uses a plugin only for the message that mentions it. Type @Noiz Mail again.
• Symptom: Claude Free will not add a second custom connector. The Free plan allows one custom connector. Remove the other one or upgrade.

On the Manage Page

• Symptom: you cannot sign in to the manage page. Use the main mailbox of the connection, the first one you connected, with its current password. A mailbox added later cannot open the manage page.
• Symptom: a mailbox is marked as rejected. Its password changed. Paste its line with the new password into the box and click Check and save.
• Symptom: “Check and save” refuses the list. One line failed; the page names it. Nothing is saved until every line passes.
• Symptom: Remove is missing next to a mailbox. That is the main mailbox, which cannot be removed. To end the whole connection, click Disconnect.

Still Stuck

Tell us which AI app you use, the mailbox address, and the exact message you saw: open a ticket or email support@noiz.co.za. We can see the audit log for your connection (tool, mailbox, folder and outcome, never content) and revoke a connection on request.
