On a Monday morning, in the teachers’ lounge in Grenoble, half of the team cannot access their academic email. The other half has access but has not received any attachments since the weekend. This scenario frequently occurs on the webmail of the Academy of Grenoble, and the causes often go beyond just a forgotten password.
Mobile Synchronization Convergence: the invisible problem of AESH in intervention
The AESH who support students across several schools in Grenoble rely on their phones to check academic messages between interventions. The Convergence messaging system, used by the Academy of Grenoble, has mobile synchronization delays that can block the receipt of alerts for several hours.

The issue stems from the synchronization protocol. By default, the mobile application retrieves messages at spaced intervals to save battery. In the field, between two schools, one might miss a schedule change or a directive from the referring teacher.
To bypass this delay, the most reliable configuration is to manually set up the account in IMAP on a third-party application (Gmail, Outlook mobile) rather than using the Convergence mobile webmail. The incoming server address remains imap.ac-grenoble.fr with port 993 in SSL. This method allows for a near-instantaneous push synchronization.

Webmail account blocking at the Academy of Grenoble: identifying the real cause
One often thinks of an incorrect password, but the majority of blocks come from an automatic lock after repeated attempts. The Academy’s security system blocks access after a limited number of unsuccessful attempts, and the unlocking delay is not always clearly communicated.
Three situations cause this lock without the user realizing it:
- An old password still saved in the browser or the phone’s mail client, which tries to connect in a loop in the background
- A session left open on a shared workstation in the establishment, which conflicts with the new connection
- The NUMEN used as the initial password never changed, which became invalid after an update to the academic security policy
Before contacting support, it saves time to check all devices where the account is configured. Deleting saved passwords in each browser and each mail application resolves the issue in most cases.
Password reset via the PIA portal
The PIA portal (Academic Internet Portal) allows users to reset their password without going through support. Since March 2026, an automated diagnostic tool helps identify the cause of the block and reduces resolution times, which previously took several hours.
The identifier follows the classic format: the first letter of the first name followed by the last name (example: SDUPONT for Sophie Dupont). If this identifier does not work, it may have been modified during a name change or a transfer between academies.
Webmail Grenoble configuration: IMAP and SMTP settings that work
The default configuration of the Convergence webmail works correctly on desktop browsers. Problems arise as soon as one switches to an external client or mobile. Here are the settings to use for a stable manual configuration:
- Incoming IMAP server: imap.ac-grenoble.fr, port 993, SSL/TLS encryption
- Outgoing SMTP server: smtps.ac-grenoble.fr, port 465, SSL/TLS encryption
- Identifier: your full academic identifier (not the email address)
- SMTP authentication: enabled, with the same identifier and password as the incoming server
One point to watch: the SMTP server sometimes refuses connections from abroad or from certain VPNs. If you are using a virtual private network, temporarily disable it to test sending.
The specific case of forwarding to a personal address
Many teachers and AESH redirect their academic email to a personal inbox (Gmail, Outlook). This forwarding works for receiving messages, but replies sent from the personal address do not carry the @ac-grenoble.fr signature. The institution requires that official exchanges come from the academic address.
The cleanest solution: configure the academic address as a sending alias in Gmail (settings > accounts > send mail as). This allows you to reply with the @ac-grenoble.fr address from Gmail, without switching between two mailboxes.
Security and GDPR archiving on academic messaging in 2026
Ministerial circular n°2026-045 of March 10, 2026, now imposes automatic archiving of sensitive emails beyond five years for administrative staff of the National Education. The tools integrated into the Convergence webmail to manage this archiving are not yet fully documented, and feedback on this point varies among institutions.
In practice, this means that some old messages may disappear from the inbox without prior notification. They are not deleted but moved to an archiving space accessible from the PIA portal.
To avoid losing professional exchanges, it is a good habit to regularly export messages in .eml format or to synchronize the inbox via a local IMAP client (Thunderbird, for example) that keeps a copy on the hard drive.
The webmail of the Academy of Grenoble remains a reliable tool when properly configured. Most connection issues can be resolved by checking saved passwords on all devices and using a manual IMAP configuration rather than the default mobile interface. For AESH on the move, this configuration makes the difference between receiving an alert on time and discovering it three hours too late.
