The webmail of the Academy of Lyon relies on a unique address, a username/password pair, and a browser. Three seemingly simple elements, but even the slightest friction can block access to professional messaging. This article compares the available login pathways, identifies real blocking points, and details the technical parameters that make the difference between smooth access and an error page.
Protocols and ports of the ac-lyon webmail: comparison of access modes
The webmail of the Academy of Lyon is not the only route to academic messaging. An email client installed on a computer or phone is an alternative, provided that the secure connection settings are mastered.

| Access Mode | Protocol | Port | Security | Main Use |
|---|---|---|---|---|
| Browser (webmail) | HTTPS | 443 | SSL certificate required | Quick consultation, any device |
| Email client (receiving) | IMAPS | 993 | TLS/SSL encryption | Permanent synchronization, local archiving |
| Email client (sending) | SMTPS | 465 or 587 | TLS/SSL encryption | Sending from Thunderbird, Outlook, Mail |
The clear POP protocol and unsecured HTTP access have been closed by the Academy’s IT department. Only encrypted protocols (HTTPS, IMAPS, SMTPS) allow connection. Any attempt on an unsecured port fails silently.
Those who encounter recurring difficulties will find solutions to access the webmail of the Academy of Lyon by first checking the alignment between these parameters and the configuration of their software.

Browser-related blocks: cookies, extensions, and session cache
The majority of connection failures to the ac-lyon webmail do not stem from an incorrect password. The browser and its privacy settings are the primary cause of blockage. Several common configurations prevent the correct loading of the authentication page or cause a looping disconnection.
Parameters that block webmail authentication
- Extensions such as ad blockers or anti-tracking tools (uBlock Origin, Privacy Badger) sometimes intercept requests to the academic authentication server, preventing the validation of the login form.
- A browser configured to delete cookies upon closing destroys the session token. The user must then reconnect each time they open the browser, and the webmail may refuse the session if the cookie is not stored correctly.
- Private browsing mode disables local storage and third-party cookies, making the connection to the institutional portal unstable, if not impossible.
- An overly large or corrupted browser cache can cause the display of an old version of the login page, incompatible with the current server.
Before any other manipulation, clearing the browser’s cache and cookies, then temporarily disabling privacy extensions, resolves a large portion of the reports.
Outdated browsers and SSL certificates
The webmail requires a valid SSL certificate. A browser that is no longer updated may not recognize the certificate from the academic server and display a security warning. A “certificate not trusted” message almost always indicates an outdated browser, not a server-side issue.
Firefox, Chrome, and Edge in their recent versions handle this certificate without alert. Safari on macOS also works, provided the system is up to date.
Migration to the Convergence portal: what changes in the login process
The Academy of Lyon has initiated a gradual migration to centralized authentication via the institutional portal (often referred to as Convergence). This change modifies the login process compared to the historical direct access on webmail.ac-lyon.fr.
With this new system, the username and password are managed in a unified manner for all academic digital services (messaging, business applications, intranet). The direct consequence: a password change on the portal affects the webmail, and vice versa.
However, users who had saved the old direct link in their favorites sometimes find themselves redirected to an error page or a double authentication. The reflex to adopt is to always go through the academic portal rather than an old link saved months ago.
Recovery of lost academic username and password
The academic email address follows the format [email protected]. The login identifier corresponds to the NUMEN or an identifier assigned by the IT department upon starting the position. These two elements are not interchangeable.
First login or expired temporary password
Upon first taking office, a temporary password is provided along with the identifier. This password has a limited validity period. If the first login is not performed within this timeframe, the password expires and access is locked.
The reset procedure goes through the academic IT support service or the recovery form available on the login page of the portal. No reset is possible without identity verification with the competent service (institution’s secretariat or IT support of the rectorate).
Configuration on mobile phone
To synchronize messaging on a smartphone, IMAP settings remain the most reliable method. The incoming server is the Academy’s IMAP server, the port is 993, and SSL authentication is mandatory. The outgoing server uses secure SMTP on port 465 or 587.
A often overlooked point: on both Android and iOS, the “username” field expects the full academic identifier, not just the part before the at sign. An error at this level causes a silent rejection without an explicit message.
Access to the webmail of the Academy of Lyon depends less on technical complexity than on the rigor regarding three parameters: an up-to-date browser with cookies enabled, the correct authentication pathway (Convergence portal rather than an old direct link), and correctly entered identifiers. When the connection fails, the problem almost always lies in one of these three links.
