Navigating the "New" TNEB Webmail: Your 2024 Transition Guide

If you work for the Tamil Nadu Electricity Board (TNEB) or TANGEDCO, you've likely noticed a significant shift in how you access your professional communication. The transition from the old mail server (150.1) to the new webmail portal (192.168.170.12) is officially here.

This update isn't just about a new look—it's a complete migration to a more secure, Zimbra-based environment designed to handle modern enterprise needs. What's Changed?

The biggest update is the migration of the entire backend. While the old portal is being phased out, TNEB has ensured a seamless transition for employees:

Automatic Migration: Your existing usernames and passwords remain the same; all data has been migrated to the new system.

Modern Interface: The new Zimbra web client offers multiple view modes, including Advanced (for high-speed connections) and Standard (for slower internet or older browsers).

New Access Point: The internal URL has shifted to a new IP address, and users may encounter a security warning in their browser. TNEB guidance suggests clicking "Advanced" and then "Accept the Risk and Continue" to proceed to the login page. Enhanced Security Measures

To protect against unauthorized access and modern cyber threats like ransomware, the new TNEB webmail has implemented stricter security protocols:

Mandatory Password Resets: Users are now required to update their passwords every 30 days.

Strong Password Policy: Your new password must be a complex mix of characters to mitigate brute-force risks. z tneb webmail new

Account Lockouts: Multiple invalid login attempts will now temporarily lock the account.

Idle Logouts: To prevent unauthorized access on shared terminals, the system will automatically log you out after a period of inactivity. Quick Reference for Employees

For those still finding their way around the new digital workspace, here are the vital links and tools:

New Webmail Access: Access through the updated internal IP or via the TNEB Employee Portal.

E-Office Portal: For digital file management and Tappal trays, use the e-office internet portal.

Support: If you encounter login issues, password resets must be requested through official HQ channels rather than simple automated "forgot password" links for security reasons.

Select Accept the Risk and Continue or Proceed to 192.168.170.12 (unsafe) to reach the login page. 3. Password Security Policies

The new system enforces updated security measures to prevent unauthorized access: Complexity: Passwords must use a mix of characters.

If you're an administrator or an advanced user, and you want to create a new account via the command line on a Zimbra server:

  1. Access the Zimbra Server: Log in to your Zimbra server.

  2. Use zmprov Command:

    • You can use the zmprov command to create a new account. The basic syntax to create an account is: 
      zmprov createAccount <accountName> <password>
    • For example: 
      zmprov createAccount john.doe@example.com P@ssw0rd

  3. Verify and Test:

    • Make sure to test the new account by logging in through the web interface or an email client.

4. Better Calendar Integration

The new webmail syncs more effectively with the TNEB internal calendar. Employees can now schedule maintenance windows or meeting rooms at the Central Office (Chennai) or circle offices directly from the email sidebar, without needing a separate plugin.

Q2: Can I access Z TNEB Webmail New from home?

A: Historically, it was restricted to the intranet. However, the "new" version allows access via a VPN (Virtual Private Network) token provided by the IT department for Gazetted officers. Line staff generally cannot access it from home.
