IMAP fetch isn’t working

When the Inbox stays empty or fetch errors appear, work through this list in order.

1. Credentials and server

• Host, port, username (full email), password/app password.

• IMAP enabled at the provider.

• Port 993 + SSL is a common working pair; follow your provider’s docs if unsure.

• Save settings, then Save & test IMAP.

2. Provider blocks

• Microsoft 365 / Google may reject “less secure” passwords — use an app password or approved IMAP auth.

• IP allowlists on corporate mail can block the Talenkai server — ask IT to allow it.

• Account lockouts after failed attempts: reset in the provider admin, then update Talenkai.

3. Prove the mailbox independently

Test the same IMAP credentials in another client (Thunderbird, Outlook IMAP). If that fails, the issue is the mailbox, not Talenkai.

4. After it works

Confirm new messages appear in Inbox and classification runs. If IMAP works but send does not, switch to the SMTP troubleshooting article.
