The Nantes academic webmail has not been responding for several weeks, and trying to reconnect to the old address will lead nowhere. The Webmel service was permanently deactivated on January 12, 2026 by the Nantes academy, as part of a national harmonization of digital tools. What seems like a malfunction is actually a scheduled shutdown, and recovering your emails now involves a different technical process.
Webmel Nantes Shutdown: What Changed on January 12, 2026
Confusion persists because the Webmel interface does not always display a clear message. Some users see a blank page, others a certificate error or a timeout. In any case, the diagnosis is the same: the Webmel server no longer processes requests.
The academy has transitioned the messaging to a national infrastructure. The old webmail (webmel.ac-nantes.fr) is no longer a valid entry point. A detailed guide on the situation is available on webmail.univ-nantes.fr on Le Petit Webmaster, which outlines the steps of this transition.
Two access modes replace the old service:
- The academic Intranet ETNA, accessible from the internal network of the institutions or via a VPN for remote staff
- The national portal messagerie.education.gouv.fr, which centralizes accounts from all academies and works from any browser
- The portal moncompte.ac-nantes.fr, which allows you to manage your credentials and reset your password before the first login to the new system
Nantes Academic Messaging: Comparison Between Old Webmel and New Portal
To measure what this migration changes in daily life, here are the technical differences between the two systems.
| Criterion | Old Webmel (discontinued) | New national portal |
|---|---|---|
| Access URL | webmel.ac-nantes.fr | messagerie.education.gouv.fr |
| Authentication | Local academic identifier | Identifier via ETNA or moncompte.ac-nantes.fr |
| Access outside the academic network | Possible but unstable | Functional from any browser |
| Password management | Reset via local assistance | Self-service via moncompte.ac-nantes.fr |
| Archiving of old messages | Stored locally on the academic server | Partial migration, verification needed |
The main point of friction concerns archiving. Messages stored on the old Webmel were not all automatically transferred. Some staff notice the absence of emails dating back several months, particularly large attachments.
Recovering Emails After the Closure of Nantes Webmail
The recovery of messages depends on how you used Webmel before its closure. Two scenarios arise.
Case 1: You only used the webmail in the browser
Your messages were stored on the academic server. During the migration, some data was transferred to the new infrastructure. To check what has been retained, log in to messagerie.education.gouv.fr with your updated credentials via moncompte.ac-nantes.fr. Browse your folders (sent, archives, trash) to identify any missing items.
If emails are missing, the only option is to contact the technical support of the academy via the ETNA platform. No self-service tool allows for the individual restoration of messages from the old server.
Case 2: You had configured an email client (Outlook, Thunderbird)
If your client was set up with IMAP, the synchronized messages remain in your software as long as you do not delete the account. Do not delete the old email profile before exporting your emails. In Thunderbird, exporting is done through the ImportExportTools NG extension. In Outlook, use the export function to a .pst file.
If the client was using POP3, your messages are already stored locally on your computer. The server-side migration does not affect them. You can reconfigure a new account pointing to messagerie.education.gouv.fr and keep the old profile in parallel for consultation.
Expired Password or Unknown Identifier on the Nantes Portal
Even after identifying the correct portal, many users struggle with authentication. The academic password expires periodically, and the transition may have triggered a forced reset without visible notification.
The portal moncompte.ac-nantes.fr allows you to redefine your password independently, provided you have entered a personal recovery email address or mobile phone number. If this information has never been entered, you must go through the digital referent of your institution or the academic support service.
For the identifier, the format generally remains firstname.lastname (with a number in case of homonymy). However, the identifier used on the old Webmel may differ from that expected by the new portal if your account was recreated during the migration. The service moncompte.ac-nantes.fr displays the active identifier after identity verification.
Cyberattack on National Education: An Aggravating Factor for the 2026 School Year
Connection difficulties were amplified by a cyberattack targeting the digital services of National Education during the start of the school year. Several academies, including Nantes, experienced disruptions to their tools for several days. School leaders in Maine-et-Loire described a situation where reverting to paper and pencil became temporarily necessary.
This attack did not delete any messaging data, but it made the portals intermittently inaccessible. Back-to-school periods concentrate peak loads and intrusion attempts, which explains why slowness or connection errors multiply in September.
If you notice an unavailability of the portal messagerie.education.gouv.fr, check the service status on the academy’s website (ac-nantes.fr) before making multiple connection attempts. Repeated attempts with an incorrect password can temporarily lock your account, adding an additional blockage to an already complicated situation.
The transition to the new portal remains the only viable path. Staff who have not yet migrated their access should do so outside of peak back-to-school times, when the servers are less busy and technical support remains reachable within reasonable timeframes.
