The academic messaging system of Caen has changed its appearance. Since the merger of the academies of Caen and Rouen, the historic webmail has migrated to a unified address under the ac-normandie domain. For teachers who used the old portal, the transition has sometimes caused confusion between identifiers, obsolete links, and new interfaces.
Normandy Academic Messaging: What Changed with the Migration to Microsoft 365
Have you noticed that your old link webmail.ac-caen.fr now redirects elsewhere? That’s normal. The Normandy academy has switched its messaging to Microsoft 365 (Exchange Online) as part of a national movement towards secure cloud solutions.

In practice, this means that your academic emails are accessible via Outlook web or the full Outlook client, without necessarily going through the historic webmail. The ARENA portal and “My HR portal” now centralize access to all services, including messaging.
This change has a direct consequence on your habits: the favorites saved to the old Caen webmail no longer work. You need to update your shortcuts to the ac-normandie portal or directly to Outlook. A detailed guide allows you to access the messaging of the Caen academy by following the updated procedure.

The integration into Microsoft 365 also brings calendar synchronization, shared contact management, and expanded storage space compared to the old webmail. For teachers juggling multiple tools, this is a real time-saver.

Academic Digital Identifier: How to Find It and Activate Your Account
The first difficulty is often the identifier. It follows a standard format: the first letter of the first name followed by the last name, all in lowercase. However, those with the same name receive a numerical suffix, and compound names can sometimes be problematic.
First Connection or New Position in Normandy
Contract workers and substitutes can activate their messaging even before starting their position, thanks to a temporary account created in advance by the academy. This is a recent development that prevents being without a professional address on the first day of school.
For the first activation, the temporary password is your NUMEN (national education identification number). If you do not know it, it is listed on your appointment order or in your I-Prof space.
- Go to the Normandy academy portal (ac-normandie.fr), section “digital services”
- Enter your academic identifier and your NUMEN as the initial password
- The system will immediately prompt you to create a personal password, which must combine uppercase letters, lowercase letters, numbers, and special characters
- Once the password is changed, you can access Outlook messaging and all services via ARENA
Forgotten Password
No need to call the rectorate. Password reset can be done online via the ARENA portal, provided you have entered a backup email address or phone number during the first connection. If not, the academic support service can still be reached by phone during office hours.
Setting Up Outlook on Your Phone to Receive Academic Emails
Checking your messaging only from a school computer limits responsiveness. With the switch to Exchange Online, setting up the Outlook app on your smartphone takes less than five minutes.
Open the Outlook app (available on iOS and Android). Add a work account. Enter your full academic email address ([email protected]). The app automatically detects the Exchange settings and asks for your academic password.
Once connected, your emails, calendar, and contacts will sync. Push notifications will alert you of new messages without having to open the app.
Why is this setup worth it? Because communications with parents, class council invitations, and information from the administration often arrive at the end of the day. Receiving these messages on your phone prevents you from missing urgent information.

Academic Messaging and GDPR: What a Teacher Should Know
The National Education emphasizes one specific point: exchanges containing student data must exclusively transit through the academic messaging system. Using a personal Gmail or Outlook address to send report cards, reports, or family contact details exposes one to a GDPR breach.
The national guidelines, relayed by the ministry and supported by recommendations from ANSSI, are clear on this subject. The academic messaging system provides a secure framework with encrypted exchanges and hosting on servers that comply with data protection requirements.
- Never forward an email containing information about a student to a personal address
- Avoid attachments containing lists of students’ names; prefer a link to the ENT
- Ensure that your academic password is distinct from your personal passwords
This framework may seem restrictive, but it protects both teachers and families. In the event of a data leak from a personal address, individual responsibility may be engaged.
The messaging system of the Caen academy, now integrated into the Normandy system and Microsoft 365, functions as a complete professional tool. Updating your access, configuring your phone, and reserving this address for sensitive exchanges are three reflexes that simplify daily life while respecting the regulatory framework.
