You have just received your assignment in the Lyon academy and you are being told about a professional email address that you have never used. This academic email AC Lyon has existed since your first day of contract. It is used to receive communications from the rectorate, inspections, and your institution. However, you need to know where to find it and how to connect to it.
Convergence AC Lyon: the portal that replaces the old direct access
Competitors often refer to the URL webmail.ac-lyon.fr as a single entry point. This address still works, but the Lyon academy now directs staff to a portal called Convergence. This portal centralizes access to email, business applications, and digital workspaces via a single sign-on (SSO).

In practical terms, you log in once on Convergence and then access your mailbox without re-entering your credentials. The time saved is significant when juggling multiple academic tools in the same session.
A technical point often overlooked: only encrypted connections (HTTPS) are accepted. If you type the address without the “s” in https, the page may not load or display an error. Check your browser’s address bar before concluding that there is a malfunction. To better understand each step, a detailed guide explains how to access the AC Lyon webmail from Convergence or through direct access.

Username and password for the AC Lyon academic email
You received a NUMEN during your appointment or your first contract. This number serves as the initial password for your academic email. Your username follows a simple format.
Username format
The username consists of the first letter of your first name followed by your last name, all in lowercase and without spaces. For example, for Maurice Ravel, the username is mravel. For hyphenated names, a dash replaces the space: jean-sebastien.bach gives jbach (or jsbach depending on the case). In case of a namesake in the academy, a number is added: mravel2.
Default password and change
The initial password corresponds to your NUMEN in uppercase. Upon your first login, the system will ask you to change it. Choose a password that meets the recently implemented enhanced requirements: minimum length, mix of characters, and absence of common words.
If you have lost your NUMEN, contact the personnel division of your DSDEN. The IT support helpdesk (04-72-80-64-88) can also unlock you if your account is locked after several failed attempts.
AC Lyon email address: understanding the format [email protected]
Your academic email address does not correspond to your login username. This is a common confusion. The address follows the format [email protected], with the full first name. Maurice Ravel receives his emails at [email protected], but he logs in with mravel.
This address is distinct from your I-Prof email, which concerns career management. The two coexist without any technical link between them. An email sent to your AC Lyon address does not appear in I-Prof, and vice versa.
Setting up an external mail client with IMAP and SMTP settings
Checking your email only via the browser is not always practical. The academy now allows connections from external clients like Thunderbird, Outlook, or your phone’s mail app, provided you adhere to specific settings.
Here are the technical settings to enter:
- IMAP server (incoming): port 993, SSL/TLS encryption required. Any attempt on an unencrypted port fails without an explicit error message.
- SMTP server (outgoing): port 587, STARTTLS encryption. Port 25, still suggested by some old tutorials, is blocked.
- Username: your full academic username (not your email address). Password: the one you set on the webmail.
On an iPhone or iPad, go to Settings, then Mail, then Accounts, then Add Account, then Other. Enter the IMAP and SMTP settings manually. On Android, the procedure varies by manufacturer, but the principle remains the same: choose “IMAP” and not “POP3”, then enter the servers with the indicated ports.
Connection issues with AC Lyon webmail: the real causes
Before thinking about a server outage, check these concrete points that block the majority of users:
- Uppercase letters in the username: the field is case-sensitive. Type everything in lowercase.
- Expired password: recent security policies require periodic renewal. If your last change was several months ago, the account may be locked.
- Outdated browser: Convergence does not work well on old versions of Internet Explorer. Use up-to-date Firefox, Chrome, or Edge.
- Cache and cookies: a previous session that was not properly closed can cause a redirect loop. Clear your browser’s cache and try again.
A full mailbox also blocks the receipt of new messages. The webmail does not always display a clear warning. If you are no longer receiving anything, delete old messages or empty the trash, which counts towards the total quota.
Automatic forwarding to a personal address (Gmail, Outlook.com) is still possible from the webmail settings. This option avoids checking two separate inboxes but does not exempt you from regularly emptying the academic mailbox to prevent saturation.
Access to AC Lyon email relies on a few simple reflexes: go through Convergence, use the correct username in lowercase, and ensure that the connection is encrypted. Blockages almost always come from an expired password or a full mailbox, not from a server issue. Keeping these points in mind, logging in takes less than a minute.
