You open your browser to check your work messages, and the page displays an error or a link that leads nowhere. Since January 2026, the academic webmail of Nantes has changed its appearance. The old Webmel service has been deactivated, replaced by a shared national messaging system. This guide helps you regain access to your academic messaging with the right reflexes, without wasting time on obsolete links.
End of the historic Webmel: what has changed for the academic messaging of Nantes
Since January 12, 2026, the Webmel service that served as the entry point for staff of the Nantes academy has been permanently deactivated. The old departmental links (ia72, ia44, ia53, and others) no longer guarantee any reliable redirection.
The Ministry of National Education has implemented a shared national messaging system. It concerns all academies, including Nantes. Your academic credentials remain the same, but the path to access your inbox has changed.
There are now two access routes. The first goes through the ETNA Intranet portal of the academy, under “Communication and collaboration,” then “Messaging.” The second directly uses the national URL for professional messaging. If you had saved a favorite link to the old Webmel, delete it and replace it with one of these two accesses. A detailed guide on connecting to the academic webmail of Nantes describes each step of the new process.
Credentials and authentication: accessing your messaging without blockage
You may have noticed that the login page sometimes requires two steps where the old Webmel only displayed one? Account management and messaging are now separate.
Finding your academic credentials
Your username remains in the format firstname.lastname (with a number added in case of duplicates). The password is that of your academic account, not that of a third-party service.
If you have never changed it, it corresponds to the NUMEN followed by specific characters defined during your first login. In case of forgetfulness, the reset procedure goes through the ETNA portal, under “My account”.
Understanding the two-step process
The login works in two successive screens. The first verifies your academic identity. The second redirects you to the national messaging system. This division may be surprising, but it enhances the security of authentication.
If the page gets stuck between the two steps, clear your browser cache. Old cookies related to Webmel may create a conflict with the new platform.

Connection issues with Nantes webmail: the real causes and their solutions
Teacher forums show that several types of blockages have been recurring since the migration. Here are the most frequent ones, along with the steps to follow for each.
- “Service inaccessible” message: this blockage often affects staff who still use an old Webmel link as a favorite. The solution is simple: go through the ETNA portal or the national URL, never through a shortcut saved before 2026.
- Password rejected after several attempts: the account temporarily locks for security reasons. Wait about fifteen minutes before trying again, or initiate the reset from the academic account management page.
- Blank page or redirect loop: clear your browser’s cache and cookies, then restart the login. On a shared browser (for example, in the teachers’ room), use private browsing to avoid session conflicts.
- Functional access on computer but not on phone: check that the IMAP or SMTP settings of your mail application are up to date. The old servers of the Nantes academy are no longer responding.
If the problem persists after these checks, contact academic support via the ETNA portal. Specify the exact error message and the browser used: this speeds up the processing of your request.
Security of academic messaging: protecting your professional exchanges
The cyberattack that targeted the Nantes and Toulouse academies caused a degraded school start for many staff members. This incident serves as a reminder that academic messaging carries sensitive data: information about students, exchanges with families, administrative documents.
Strengthening the security of your account
Change your password at least once a term. Choose a combination of at least twelve characters, mixing uppercase letters, lowercase letters, numbers, and symbols. Never reuse your academic password on another site.
Enable login notifications if the option is available in your settings. They alert you when a session opens from an unusual device or location.
Recognizing phishing attempts
Fraudulent emails impersonating the Nantes academy have multiplied after the cybersecurity incidents. A message asking you to “confirm your credentials” via an external link is almost always a phishing attempt.
The academy never asks for your password via email. If in doubt, do not click on any links and forward the message to the digital referent of your institution.

Setting up your academic messaging Nantes on phone or tablet
Checking your messages from a smartphone avoids depending on the computer in the teachers’ room. The setup requires a few precise adjustments.
- Receiving protocol: choose IMAP rather than POP to synchronize your messages across multiple devices without deleting them from the server.
- Incoming and outgoing server: use the addresses provided by the national messaging system (accessible from your account settings on the portal). The old local academic servers no longer work.
- Port and encryption: enable SSL/TLS encryption. The port varies according to the protocol; check the updated documentation on the ETNA portal.
On iOS devices, add the account via Settings, then Mail, then “Add Account.” On Android, the procedure goes through the native mail app or a third-party app like Gmail. In both cases, enter the full address in the format [email protected] as the username.
The academic messaging of Nantes now operates on a more robust national infrastructure than the old Webmel. Localized outages should become rarer. Keep your access up to date, delete old favorites, and regularly check your account’s security settings: these are the three actions that prevent most of the reported blockages since the migration.
