You open your browser in the morning, type in the old URL of the academic webmail of Lyon saved in your favorites, and the page remains blank or returns a certificate error. This situation has been common since the academic IT department closed unencrypted access and redirected traffic to the Convergence portal.
For staff who have not updated their connection habits, the blockage can last several days without an explicit error message guiding them to the solution.

Blocked connections to Lyon’s webmail: understanding the technical cause
The majority of connection failures to the academic messaging system do not stem from a forgotten password. They arise from an infrastructure change that many users have not identified.
The IT department of the Lyon academy has closed unencrypted HTTP connections and the POP protocol without TLS. In practical terms, only secure HTTPS, IMAPS, and SMTPS protocols still work. Old configurations fail silently, without an explicit message for the user. You are left facing an endless loading screen or a certificate error, without understanding why.

For those looking for a step-by-step guide on accessing Lyon’s academic webmail, the first thing to check is the protocol used by your email client or browser.
If you configured Thunderbird or Outlook several years ago with classic POP on port 110, the connection will no longer work. The attempts do not display any “protocol refused” alerts: they fail silently. This makes diagnosis difficult without knowing about this technical evolution.
Convergence portal of the Lyon academy: the right entry point
Old direct links to the webmail (favorites from several years ago, URLs copied in internal documents) redirect to dead pages or errors. The Convergence portal is now the main entry point to access the academic mailbox.
Why old favorites no longer work
Successive updates to the academy’s digital infrastructure have changed access paths. A favorite saved before these changes points to a server that no longer accepts direct connections. You do not receive a clear error page, just a timeout or a broken redirect.
The most reliable solution: delete the old favorite and create a new one directly from the authentication page of the Convergence portal. You can access it via the official website of the Lyon academy, under the “Access to applications” section.
Authentication and academic credentials
The login ID is the same as that used for all National Education services (Arena, PIA, management applications). The initial password is often the NUMEN in uppercase letters, but most staff have changed it since.
If forgotten, the reset procedure goes through the academic portal, not through a “forgot password” link on the webmail itself. The Convergence webmail does not offer autonomous password recovery: you must go back through the centralized authentication interface or contact the IT support.
IMAP and SMTP configuration for Lyon’s academic messaging
Configuring an email client on a smartphone or computer remains the most practical way to manage your academic emails daily. The settings are the same regardless of the device (iOS, Android, Windows, macOS), but it is noted that input errors are the primary cause of failure.
Here are the parameters to enter for a functional configuration:
- Incoming server (IMAP): use exclusively the IMAPS protocol on port 993, with SSL/TLS encryption enabled. Port 143 without encryption no longer works.
- Outgoing server (SMTP): use SMTPS on port 465 (SSL) or port 587 (STARTTLS). Both are accepted, but port 587 with STARTTLS is the most compatible with modern clients.
- ID: the full address in the format [email protected] (a number may be added in case of homonymy).
- Password: that of the academic account, the same as used on the Convergence portal.
Feedback varies on this point, but some users report that the automatic configuration offered by Outlook or Apple Mail poorly detects the academy’s servers. In this case, switching to manual configuration and entering each parameter resolves the issue in the vast majority of situations.
Security of the academic mailbox: common mistakes to avoid
Automatic redirection of academic emails to a personal mailbox (Gmail, Outlook.com) is no longer allowed. This restriction exists for reasons of confidentiality regarding school and administrative data. Attempting to set it up will not succeed.
Keeping your academic credentials outside of a secure password manager is a real risk. Phishing campaigns targeting National Education staff are increasing. An email mimicking the academic portal and asking to “verify your credentials” is a classic warning sign.
Some concrete reflexes to protect your access:
- Never click on a login link received by email. Always manually type the address of the Convergence portal or use a verified favorite.
- Check that the URL starts with https and that a padlock appears in the address bar before entering your password.
- Change your academic password at least once a year, avoiding logical sequences or dictionary words.
Access to Lyon’s academic webmail ultimately hinges on two specific points: using the correct entry point (Convergence portal, not an old favorite) and ensuring that your connection settings comply with the encrypted IMAPS and SMTPS protocols. A corrected configuration in five minutes can prevent weeks of missed emails.
