It’s Sunday evening, the rectorate has sent a notice for a training session the next morning, and we realize that we haven’t checked our academic inbox for three days. The reflex is to open a browser on your personal computer and type in the webmail address. Except that nothing goes as planned: forgotten password, exceeded quota, or an Android smartphone too old to handle the IMAP protocol properly.
This guide covers the concrete situations faced by staff at the Strasbourg academy when they try to access their academic email from home.

For those who want a complete reminder of the basic steps, we can access the Strasbourg academic email through a dedicated guide that details each action.
Setting up an old Android smartphone without risking account suspension
A Galaxy S7 running Android 8 or a Redmi Note 5 that hasn’t received an update in two years doesn’t always handle recent SSL certificates. The classic symptom: the native mail client displays “Unable to verify the server’s certificate” and refuses the connection.

The temptation is to check the “Accept all certificates” option in the advanced settings. Never check this option on a personal device. It disables security verification and can trigger a report on the academic server side, not to mention the risk of interception of your credentials on a public Wi-Fi network.
IMAP protocol and ports to enter manually
On an old device, automatic detection almost always fails. You need to enter the settings manually:
- IMAP incoming server: courrier.ac-strasbourg.fr, port 993, SSL/TLS encryption
- SMTP outgoing server: the same domain, port 465 in SSL/TLS (or 587 in STARTTLS depending on the version of Android)
- Username: your first.last name as it appears in the academic directory, not your full email address
- Password: the one for the Roundcube webmail, not the password for your ENT or I-Prof
If the mail client still refuses the connection after these settings, the problem often comes from an outdated version of TLS on the device. Feedback varies on this point, but a reliable solution is to use a third-party client like FairEmail or K-9 Mail, which come with their own certificate stack and bypass the system’s limitations.
Roundcube from a home browser: the settings that change everything
The Strasbourg academy uses Roundcube as its webmail interface. Unlike Outlook, used in other academies, Roundcube consumes little bandwidth. This is a real advantage for ADSL connections still common in some rural areas of Alsace.
You access the webmail via courrier.ac-strasbourg.fr directly in the browser’s address bar. No need to go through the ac-strasbourg.fr site if you know the URL.
Mailbox quota and disappearing messages
The most common trap when checking your email from home is the quota. When the mailbox is full, new messages are no longer delivered, without error notification on the sender’s side in some cases. You don’t receive anything and you don’t know it.
To check the remaining space, Roundcube displays a gauge at the bottom left of the interface. If it exceeds three-quarters, it’s time to declutter. Start with the “Sent” folder: large attachments sent accumulate there and weigh as much as received messages.
Manually empty the Trash folder: Roundcube does not automatically purge it at each logout. Deleted messages remain counted in the quota as long as the trash is not explicitly emptied.
First connection and password recovery from home
During a first connection, the username generally corresponds to the initial form of the first name followed by the last name (first letter of the first name + dot + last name). The NUMEN serves as the initial password.
For AESH in Bas-Rhin, the NUMEN is sent upon signing the contract to the personal email address. This message sometimes ends up in spam. If you can’t find it, you need to contact the administrative manager at the dedicated address for AESH at the academy.
Resetting when you no longer have access to the workstation
From home, you cannot use the internal reset procedure that requires being connected to the institution’s network. The only reliable way is to go through the identifier management form accessible from the webmail login page, under “Manage my password.”
This form requires the NUMEN and date of birth. Without your NUMEN, no autonomous reset is possible. Write it down somewhere secure as soon as you receive it; it is the keystone to all access to your academic digital services.
Migration to Esterel 2.0: what changes for home connection
The Strasbourg academy is part of the Grand Est academic region, which plans a gradual migration to the Esterel 2.0 platform by June 2026. This migration involves a unified interface and enhanced integration with collaborative tools like DT-Ulysse.
Specifically, for home connection, this means that the current IMAP and SMTP settings may change. Staff who have manually configured their smartphone or email client will likely need to update their server settings after the switch.
No specific switch date by institution has been communicated at this stage. It is recommended to monitor announcements on the ac-strasbourg.fr portal and not to delete your current Roundcube configuration until the migration is confirmed for your profile. A temporary dual configuration (old and new server) will prevent you from being without access on the day of the transition.
The key point to remember: the academic email in Strasbourg is a tool that works well from a home network, provided you know the right settings and monitor your quota. Keep your NUMEN accessible, regularly empty your Roundcube trash, and prefer a third-party mail client on aging Android devices rather than disabling security verification.
