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. z tneb webmail new
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.
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
