The academic messaging system of Bordeaux relies on a personal account in @ac-bordeaux.fr assigned to each staff member of the academy. Convergence, on its side, refers to the technical interface that allows access to this account from a browser. Confusing the two is akin to confusing a mailbox with the key that opens it.
IMAP and SMTP Protocols Behind the Convergence Webmail
Before distinguishing the uses, it is essential to understand what flows beneath the interface. Convergence relies on a IMAP server for receiving and an SMTP server for sending. These two protocols operate independently of the webmail: any email client (Thunderbird, Outlook, Apple Mail, mobile app) can connect to it as long as the correct settings are provided.

The server to indicate is that of Convergence Bordeaux, along with the associated secure ports. The security layer (TLS encryption) protects the exchanges between the user’s workstation and the academic server. When a malfunction occurs on a heavy client, the current recommendation is to first test access via the Convergence webmail to isolate the origin of the problem: if the webmail works, the issue lies with the local configuration.
Several recent guides remind us that Convergence is just one entry point among others to the same inbox. A teacher who reads their messages on Thunderbird in the morning and on the webmail in the afternoon is accessing the same account, synchronized via IMAP. No messages are duplicated or lost, provided the client is configured in IMAP (and not in POP, which downloads messages locally).

To understand the ac Bordeaux messaging and convergence in detail, the distinction between the account (the @ac-bordeaux.fr address) and the front-end (Convergence, Thunderbird, or others) remains the starting point.
Ac Bordeaux Messaging: Account, Credentials, and Scope of Use
The academic email account is created automatically upon assignment to the academy. The identifier generally follows the format firstname.lastname, sometimes supplemented by a number in case of name duplication. The initial password must be changed upon first login.
Since the security campaign launched in 2024, the password expires after twelve months and must be renewed each year. An email from the rector, sent to all staff, also confirmed the removal of redirections to external email services (Gmail, Orange, personal Outlook). After the deadline set for the end of September 2024, these automatic forwards will no longer function.
This strict scope responds to a logic of security for professional communications. Exchanges containing student data, administrative documents, or information related to exams must only transit through the academic messaging system.

Password Reset
In case of forgetting, the procedure goes through the AIDA portal, accessible from the Convergence login page (link “Forgot password”). Resynchronizing the password via this portal is now the preferred method before reporting any incidents to technical support.
Convergence Bordeaux: Webmail Functions Beyond Email
Convergence is not limited to sending and receiving emails. The interface includes a calendar and a shared address book, two tools often underutilized. The calendar allows creating events visible to other staff members of the academy, facilitating coordination without resorting to a third-party service.
The address book is fed by the academic directory. Searching for a colleague by name or institution works directly from the message composition bar. This point distinguishes the Convergence webmail from a simple IMAP client: access to the academic directory is native, whereas software like Thunderbird does not offer this feature without additional configuration.
The interface remains simple, inherited from the Oracle Communications solution. Navigation is done via tabs (mail, calendar, preferences). Automatic message sorting filters can be configured directly from the webmail, an asset for organizing incoming flows by sender or subject.
Choosing Between Convergence and an Email Client
The choice depends on the context of use, not on a technical superiority of one over the other. Here are the criteria that guide the decision:
- The Convergence webmail is suitable for occasional consultations from any connected workstation, without installation. It provides access to the calendar and the academic directory without configuration.
- A heavy client (Thunderbird, Outlook) offers offline reading, finer folder management, and the ability to centralize multiple email accounts in a single interface.
- Mobile applications (Mail on iOS, Gmail or Outlook on Android) allow receiving real-time notifications, provided the IMAP server and SMTP port of the Convergence Bordeaux server are configured.
Convergence serves as a reference for diagnosing problems. A message absent from Thunderbird but visible on the webmail indicates a local synchronization issue. A message absent from both indicates a server-side problem or upstream filtering.
Points of Caution When Configuring IMAP
Configuring an external client requires entering the incoming server (IMAP), the outgoing server (SMTP), and enabling TLS encryption. A common mistake is using the POP protocol instead of IMAP: POP deletes messages from the server after downloading, making them inaccessible from the webmail or another device.
The server address, port number, and type of encryption are included in the discovery guides distributed by the academy’s IT department. In case of doubt, connecting to the Convergence webmail remains the quickest test to confirm that the account is functioning normally.

The ac Bordeaux messaging and Convergence are not two distinct services but two layers of the same system. The @ac-bordeaux.fr address stores the data, Convergence displays it. Keeping this distinction in mind simplifies every operation, from configuring a new phone to resolving a synchronization incident.
