When you arrive at the Créteil academy, the first real difficulty is not pedagogical: it’s managing to connect to your professional email. The address in the format [email protected] provides access to the academic portal, the Arena applications, and all internal resources. However, in 2026, a migration to the national email system of the ministry complicates matters for newcomers as well as for current staff.
Migration to the national email system: what changes for staff
The Créteil email system is in the process of transitioning to the national platform of the ministry. Two entry points coexist depending on the migration status of the account: the old academic Webmel (webmel.ac-creteil.fr) and the new national interface.
In practice, this means that a colleague in the next office may connect using a different URL than yours, with the same type of identifier. Connection failures occur despite correct identifiers, simply because the account has already transitioned to the new platform while the user is still trying the old portal.
If the usual login page returns an error, you should test access via the national portal before initiating a reset procedure. Wasting time changing your password when the problem lies with the access URL is a common pitfall during this transition period.
To access the Créteil webmail under good conditions, it is recommended to first check with the establishment’s secretariat if the account has already been migrated.
Academic username and password: retrieving access without going in circles
The username takes the form of pnom (initial of the first name followed by the last name, sometimes completed with a number). The default password is the NUMEN. If you do not know your NUMEN, only the secretariat of your establishment or your managing service can provide it to you.
To retrieve a forgotten username, the portal identifiant.ac-creteil.fr allows you to recover it by entering your NUMEN and date of birth. The email password is also the one for Arena and all academic services: changing it impacts all these accesses simultaneously.
The academy may impose periodic password renewal. When this renewal occurs during the national migration, feedback varies on this point: some staff report that the change takes effect immediately on both portals, while others notice a propagation delay.
Resetting: the correct procedure
The academic identity management portal initiates the reset after verifying identity. You go through a dedicated page, enter your NUMEN and date of birth, and then set a new password.
- First, check that the problem does not come from the login URL (old Webmel or new national portal)
- Have your NUMEN ready before starting the procedure, otherwise you may have to contact the secretariat in parallel
- After resetting, test the connection on Arena and the webmail to confirm that the new password has propagated correctly
Configuring an IMAP or SMTP mail client: server settings and the post-migration trap
Many staff prefer to use Thunderbird or their phone’s mail app rather than the web interface. The servers to be entered are those of the academy: IMAP for receiving, SMTP for sending. The POP3 protocol remains available but IMAP maintains synchronization between devices.
The national migration introduces a concrete problem for users of external clients. Feedback from staff indicates that after the transfer to the national email system, a specific password for third-party applications may be necessary, distinct from the password used on the web portal. Thunderbird or the mobile app then refuse to connect with the usual password.
Settings to enter in the mail client
- IMAP receiving server: use the address provided by the academy (check if it has changed with the migration)
- SMTP sending server: same caution, the SMTP server address may differ between the old system and the new one
- Port and encryption: prefer SSL/TLS to secure communications
- Username: the same as for the web portal (format pnom), unless otherwise indicated post-migration
Academic phishing: a real risk at every start of the school year
Phishing campaigns targeting staff at the Créteil academy are not a theoretical risk. Alerts have been issued specifically for the academy, recommending to never transmit identifiers, passwords, or bank details via email or phone.
The back-to-school period concentrates attempts: new staff, unfamiliar with the official communications of the academy, are prime targets. An email asking to “verify your account” or “update your information” via an external link never comes from academic services.
If in doubt about a message received at the address ac-creteil.fr, contact the digital referent of the establishment directly instead of clicking on a link. Redirecting academic mail to a Gmail address or other private email service, sometimes practiced to centralize inboxes, also poses a problem: entrusting student and parent data to a private operator without oversight raises ethical and potentially regulatory questions.
The professional email of the Créteil academy is going through a transition phase that makes the first steps more delicate than usual. Keeping in mind the coexistence of the two portals, securing your application password if the account has migrated, and remaining vigilant against phishing attempts at the start of the school year: these three reflexes are enough to avoid the majority of blockages reported by staff this year.
