The AMU webmail relies on the Microsoft 365 / Outlook infrastructure, accessible via the university’s centralized CAS authentication. Understanding this technical foundation is key to resolving the majority of connection issues encountered by students and staff at Aix-Marseille University.
IMAP Protocol and Outlook Configuration: What the Web Interface Hides
The AMU university email operates on the IMAP protocol with Microsoft 365 synchronization. Specifically, each mailbox is hosted on Microsoft servers and synchronized in real-time, whether accessed via the webmail browser, a desktop Outlook client, or a mobile application.

This architecture has a direct consequence: standard IMAP settings (incoming server, port, SSL/TLS encryption) are preferred by the Microsoft ecosystem. Simply entering the university email address in the Outlook desktop or mobile app triggers autodiscover, which automatically configures the account without manual server entry.
We recommend never forcing a manual IMAP configuration on a third-party client (Thunderbird, Apple Mail) without first verifying that OAuth2 authentication is supported. Older simple password authentication methods are gradually being disabled on university Microsoft 365 tenants, leading to silent connection failures on incompatible clients.

To access the AMU webmail with Airbuzz, the procedure first involves understanding this unified authentication mechanism, which links email, ENT, and documentary resources under a single set of credentials.
Activating the ENT Account and AMU Credentials: The Sequence to Follow
Access to AMU email is contingent upon prior activation of the ENT account on the Sésame portal (sesame.univ-amu.fr). Without this step, no connection to the webmail will succeed, even with valid credentials on paper.
The activation sequence follows a precise pattern:
- The username consists of the first letter of the last name followed by the student number, as it appears on the enrollment certificate.
- The initial password corresponds to the INE code, entered in lowercase and without spaces. This password must be changed during the first login on Sésame.
- Once the account is activated, the same credentials provide access to the ENT, Outlook webmail, library resources, and all AMU digital services via the CAS portal.
An account not activated on Sésame blocks all AMU digital services, including email. This is the first check to perform in case of a connection failure to the webmail.
Resetting the ENT Password
Password resets can only be done through the Sésame portal. Standard Microsoft recovery procedures (like “forgot password” on outlook.com) do not work on AMU university accounts, as authentication is delegated to the university’s CAS.
We observe that the majority of support tickets related to AMU email concern an expired password or one that has not been changed after the initial activation. The IT department imposes periodic renewal, and an expired password results in a CAS error without an explicit message on the Outlook side.
Connecting to AMU Webmail from a Browser and Mobile Client
The direct access URL to the webmail is mail.univ-amu.fr, which redirects to the CAS authentication portal before opening the Outlook Web App (OWA) interface. The browser does not matter, but cookie or script blocking extensions (like uBlock Origin in strict mode, for example) may interfere with the CAS redirection and cause an authentication loop.
On mobile, two options coexist. The Outlook app (iOS and Android) natively manages university Microsoft 365 accounts via autodiscover. The native Mail app on iOS or Samsung also works, provided the system supports OAuth2 for Exchange/Microsoft 365 accounts.
Managing Notifications on Mobile
Push notifications for university email depend on the type of client used. Outlook mobile enables them by default. On native clients, IMAP notifications are often delayed by several minutes compared to Exchange/ActiveSync push notifications.
For users who check their university inbox alongside a personal email account, we recommend setting up a dedicated account in Outlook mobile rather than redirecting to Gmail or another provider. Email forwarding (documented on AMUpod) works, but it desynchronizes folders, drafts, and read indicators between the webmail and the third-party service.
Resolving CAS Errors and Webmail Session Issues
The most common error on mail.univ-amu.fr is the CAS redirection loop. It manifests as an infinite page reload of the authentication page after entering credentials, without a visible error message.
- Clear the browser’s cache and cookies, specifically targeting the domains univ-amu.fr and microsoftonline.com.
- Ensure that the system clock on the computer is synchronized. A discrepancy of a few minutes is enough to invalidate CAS authentication tokens.
- Temporarily disable browser extensions that modify HTTP headers or block JavaScript redirections.
- Test the connection in private browsing mode to isolate a corrupted browser profile issue.
If the loop persists, the issue usually lies with the ENT account (expired password, account locked after failed attempts). The contact page for the Digital Department (DirNum) at AMU, accessible from the CAS portal, allows for opening a support ticket.
Expired Session and Automatic Logout
The CAS portal enforces a logout after a period of inactivity, which varies according to the tenant’s configuration. Closing the webmail tab without logging out via the dedicated button can leave an orphaned CAS session, complicating immediate reconnection from another tab or browser. The university’s recommendation to always use the logout button before closing the browser remains relevant, especially on shared computers in university libraries.
The AMU webmail, despite its apparent ease of access, relies on a CAS-Microsoft 365 authentication chain where each link (Sésame activation, password validity, client OAuth2 compatibility, cookie status) can block the connection. Identifying the faulty link remains the most useful technical skill for any regular user of Aix-Marseille university’s email system.
