The academic messaging service of Strasbourg is the email service provided to all staff of the academy, including teachers, administrative agents, and contractors. Each agent has an address in the format [email protected], linked to a personal identifier and a password. This account provides access to webmail, as well as several e-services related to career management and administrative tasks.
Connection Logging and Security of Strasbourg Webmail
Since the DSI updates of 2022-2023, connections to the academic webmail are subject to centralized logs. Each sensitive action (password change, mailbox delegation, access from abroad) is recorded and analyzed by the academic SSI teams to detect anomalies.

This system is part of the Information Systems Security Policy of the National Education (PSSI-Éducation, version 2.0 published in 2022). In practice, this means that an unusual connection, for example from a foreign country, may trigger an automatic verification or a temporary account lock.
To access the professional messaging service of the Strasbourg academy, it is essential to maintain a strong password and never share it. The same identifier provides access to resources like I-Prof (career management) or DT-Ulysse (reimbursement of travel expenses), making the confidentiality of the access code even more critical.

Identifier and Password: Setting Up Access to Academic Messaging
The access code consists of an identifier (often linked to Numen) and a password. The first login may sometimes require password initialization via the academy’s dedicated platform.
Finding Your Numen or Resetting Your Password
The Numen can be obtained from the head of the institution or from the service that manages the agent’s administrative file. For the password, resetting is done online on the academic portal.
If the online procedure fails, the recourse is through the academic DSI support service. Note: since the implementation of the national Colibri platform, certain procedures are no longer handled by local academic services. Checking which portal to act on before contacting support avoids unnecessary back-and-forth.
Recognizing an Official Message
Messages from hierarchy or colleagues within the academy carry the extension @ac-strasbourg.fr. Those from the Ministry of National Education use @education.gouv.fr. Any other sending domain for a supposedly administrative message should raise suspicion.
Configuring a Mail Client with IMAP and SMTP Settings
The webmail accessible via courrier.ac-strasbourg.fr is suitable for occasional consultation. For daily use on a computer or smartphone, configuring a mail client (Thunderbird, Outlook, mobile app) offers more flexibility.
The configuration relies on two protocols:
- IMAP for receiving: this protocol synchronizes messages between the server and the client, allowing you to access your emails on multiple devices without duplication or loss
- SMTP for sending: it manages the delivery of outgoing messages to their recipients, authenticating with the same academic credentials
- The port and encryption (SSL/TLS) to be specified depend on the client used, but the academy provides these settings in the DSI documentation accessible from the intranet
Using IMAP rather than POP3 is preferable: POP3 downloads messages and deletes them from the server, which poses a problem if multiple devices are used. IMAP keeps everything on the server and synchronizes folders.
Managing Mailing Lists and Group Messages
The Strasbourg academy uses mailing lists to transmit information to all concerned staff. These lists allow sending a single message to a predefined group (all teachers in a district, all AESH in Bas-Rhin, etc.).
As a recipient, it is useful to create sorting rules in your mail client to automatically classify these group messages into a dedicated folder. The volume can be substantial, and sorting by sender or subject prevents individual exchanges from getting lost in the collective flow.
Avoiding the “Reply All” Trap
On a mailing list, clicking “Reply All” sends the response to all members of the list. This common mistake can disseminate personal information to hundreds of colleagues. Always check the recipient field before sending remains the most effective precaution.

Connecting to Academic Webmail from a Personal Device
Accessing webmail from home or a personal device does not pose technical difficulties: simply go to the portal courrier.ac-strasbourg.fr and authenticate. The constraint lies in the security of the device used.
A shared computer or public Wi-Fi network exposes credentials to interception risks. Two precautions reduce this risk:
- Use private browsing to prevent credentials from being saved in the browser
- Always log out after each session, especially on a device that is not strictly personal
- Check that the connection is indeed HTTPS (padlock in the address bar) before entering your credentials
The access logging implemented by the DSI since 2022-2023 allows for the detection of suspicious connections, but the first line of defense remains the user’s behavior.
The academic account goes beyond just an email box: it serves as an entry point to all career management and administrative tools. Protecting this access with a unique password, different from those used on personal services, remains the simplest and most effective measure on a daily basis.
