The historic webmail of the Nantes academy (Webmel, ia44, ia72, ia53) was definitively deactivated on January 12, 2026. Teachers who still attempt to use these old addresses encounter an error page or a silent redirect. The single entry point for professional messaging is now the national platform messagerie.education.gouv.fr, common to all academies. Understanding this new access pathway, its variations, and its bottlenecks allows for real time savings with each connection.
Old ac-nantes webmail and national messaging: what has changed
| Criterion | Old Webmel (before January 2026) | National Messaging (since January 2026) |
|---|---|---|
| Access URL | webmail.ac-nantes.fr, ia44, ia72, ia53 | messagerie.education.gouv.fr |
| Authentication | Local academic identifier | Access via moncompte.ac-nantes.fr or ETNA intranet |
| Scope | Nantes academy only | All French academies |
| Mobile access | Web interface poorly adapted | Mobile browser compatible, IMAP configuration possible |
| Current status | Deactivated | Active, sole official service |
The shift to a centralized service has removed local particularities. The old academic URLs are now obsolete and no longer lead to any functional inbox. If you have kept a favorite link to webmail.ac-nantes.fr, it needs to be replaced.
A detailed guide allows you to access the webmail of the Nantes academy by following the updated pathway after this migration.
Connection via the ETNA intranet: the current pathway for teachers
The official access route goes through the academic intranet ETNA. From the “Applications and Portals” menu, the “Communication and Collaboration” section provides access to the national messaging. This detour may surprise teachers who are used to typing a URL directly into their browser.
Concrete connection steps
- Open your browser and go to the portal moncompte.ac-nantes.fr to authenticate with your usual academic credentials.
- Once logged in, access the ETNA intranet, then click on “Applications and Portals” and select “Communication and Collaboration”.
- Click on the link to the messaging: you will be redirected to messagerie.education.gouv.fr, where your inbox opens directly thanks to single sign-on (SSO).
The passage through moncompte.ac-nantes.fr remains mandatory to establish the SSO session. Attempting to access messagerie.education.gouv.fr directly without this step often results in an authentication error or a redirect loop.
Lost password or first connection
Password reset is done exclusively on moncompte.ac-nantes.fr, via the “Forgot Password” procedure. For teachers newly appointed to the academy, activating the academic account precedes any attempt to connect to the messaging. Without this active account, no access to ETNA or the national messaging is possible.
Academic messaging connection issues: real blockages
The difficulties reported by teachers since the migration focus on a few recurring points. Identifying them avoids wasting time with unnecessary manipulations.
The old URLs ia44 or ia72 cause an “inaccessible service” error. This message does not indicate a temporary outage: these addresses are definitively out of service. The only solution is to go through the ETNA pathway described above.
Browsers that have cached old academic session cookies can create redirect loops. Clearing the cache and cookies related to the domain ac-nantes.fr resolves the majority of these cases. However, if the problem persists after this manipulation, it is usually an account issue (expired password, account not activated).
The cyberattack that affected the National Education at the start of the 2025 school year has also left traces in some departments. Teachers in Maine-et-Loire reported prolonged disruptions in accessing their digital tools, including messaging. These occasional incidents are related to national infrastructure, not to user-side mishandling.
Setting up academic messaging Nantes on mobile or mail client
Checking professional emails from a phone or software like Thunderbird requires IMAP or Exchange configuration. The national platform supports these protocols, but the parameters to be entered have changed with the migration.
Connection parameters to use
The incoming server (IMAP) and outgoing server (SMTP) now correspond to the servers of messagerie.education.gouv.fr. The old parameters related to ac-nantes.fr no longer work. The identifier remains the full address in the format [email protected], even if the hosting is national.
The IMAP port with SSL/TLS encryption must be enabled for the connection to succeed. Without encryption, most modern mail clients refuse the connection or display a security warning.
On smartphones (iOS or Android), adding an “Exchange” account rather than IMAP simplifies the synchronization of the calendar and contacts in addition to emails. This option combines several features into a single configuration.
Security of academic messaging: reflexes to adopt
The centralization of messaging on a national platform enhances overall security but does not exempt individuals from precautions. Phishing attempts targeting ac-nantes.fr addresses have increased since the migration, precisely because many teachers are looking for new connection instructions online.
- Never click on a link for “updating your academic messaging” received by email: the academy does not operate this way. Any password change goes through moncompte.ac-nantes.fr.
- Enable two-step verification if your account offers it. This additional layer of security blocks most fraudulent access even in the case of a compromised password.
- Report any suspicious email via the reporting function integrated into the national messaging, which directly feeds into the academic anti-spam filters.
A unique and complex password for the academic account remains the first barrier. Reusing a personal password for professional messaging exposes you to cross-compromise risk in case of data leaks on another service.
The transition to messagerie.education.gouv.fr has simplified the technical architecture, but it has also disoriented many teachers used to their old references. Updating favorites, clearing the cache once and noting the ETNA pathway somewhere accessible covers almost all connection issues encountered daily.
