The webmail Convergence of the Toulouse academy is based on the IMAP protocol coupled with authenticated SMTP sending. Configuring this academic email on a smartphone, tablet, or desktop client requires entering specific parameters, but also adhering to security prerequisites that standard guides do not always detail. This article compares configuration methods across platforms and highlights the technical constraints that condition the success of synchronization.
TLS Prerequisites and Operating System Compatibility
Before entering any parameters, the version of the operating system determines whether the connection will succeed. Academic webmails, including Convergence, have gradually disabled TLS 1.0 and TLS 1.1 between 2022 and 2024. Only TLS 1.2 minimum is accepted for encrypted IMAP and SMTP connections.

This constraint causes silent failures on older devices. An Android smartphone prior to version 5 or 6, or an email client that has not been updated for several years, will refuse the connection without always displaying an explicit error message.
| Platform | Minimum Recommended Version | Natively Supports TLS 1.2 | Risk of Blocking |
|---|---|---|---|
| Android | 6.0 (Marshmallow) | Yes | Low |
| iOS | 12.0 | Yes | Low |
| Windows (Outlook) | Windows 10 + Office 2016 | Yes | Low |
| macOS (Mail) | 10.13 (High Sierra) | Yes | Low |
| Android 4.x or lower | Unsupported | Not Guaranteed | High |
| Thunderbird < 60 | Not Recommended | Partial | Moderate |
The official guides from the academy now mention the necessity of having an OS still supported by its publisher. A device that no longer receives security updates will likely be unable to negotiate the required encryption.

Before any attempt, simply check the system version in the device settings (Settings > About Phone on Android, Settings > General > About on iOS). This check takes a few seconds and avoids hours of unnecessary troubleshooting.
IMAP and SMTP Settings for Convergence Webmail at Toulouse Academy
To configure the Convergence webmail of Toulouse Academy on an email client, the fields to fill in are the same regardless of the application used. The differences lie in the location of the menus, not in the values themselves.
- IMAP Server: messagerie.ac-toulouse.fr, port 993, SSL/TLS encryption
- SMTP Server: messagerie.ac-toulouse.fr, port 465, SSL/TLS encryption, authentication required
- Username: your full academic identifier (format firstname.lastname or numerical identifier depending on your profile)
- Password: the one used to access the webmail via the browser
The IMAP protocol synchronizes messages between the server and the device. An email read on the smartphone appears as read in the Convergence webmail, and vice versa. In contrast, the POP3 protocol, sometimes offered by default in certain clients, downloads messages locally without bidirectional synchronization.
Choosing IMAP over POP3 maintains consistency across all your devices. If you check your academic email from a desktop computer, a phone, and a tablet, this distinction has a direct impact on your daily organization.
Configuration Differences Between Android, iOS, and Desktop Clients
On iOS, the native Mail app manages automatic parameter detection when the domain is recognized. For ac-toulouse.fr, this detection often fails. You then need to select “Other” as the account type and manually enter the IMAP/SMTP parameters listed above.
On Android, behavior varies by manufacturer. The built-in Gmail app offers the addition of an “Other (IMAP)” account. Samsung Email follows a similar path but names the fields differently. In both cases, port 993 for receiving and port 465 for sending remain the values to enter.
Desktop clients offer more control. Thunderbird, for example, attempts auto-configuration based on the email address. If it fails, manual entry is more guided than on mobile, with drop-down menus for encryption type and port.
Outlook (Microsoft 365 or 2016 and later versions) accepts IMAP accounts via the account setup wizard. The only peculiarity: Outlook sometimes requires unchecking the “Exchange” option that is offered by default and manually forcing the IMAP type in the advanced settings.
Synchronization Frequency and Data Consumption
Most mobile clients offer a synchronization interval: push, every 15 minutes, every 30 minutes, or manual. The push mode maintains a constant connection to the server, which consumes more battery and mobile data.
For academic professional email, a 15 to 30-minute interval is a reasonable compromise between responsiveness and battery life. Notifications arrive with a slight delay, but the battery lasts significantly longer.
Multifactor Authentication and Future Developments to Anticipate
Since 2024, the Digital Education Directorate (DNE) has been promoting the generalization of multifactor authentication (MFA) for academic services. Some pilot academies, notably Rennes and Lyon, have already made it mandatory for access to webmails and ENT outside the internal network.
Toulouse has not yet activated this requirement. The DNE/SDN notes published in 2023 and 2024 indicate that the extension of MFA to academic emails is planned in the short or medium term. This development will change the configuration procedure on third-party clients.
With MFA, a password alone will no longer suffice. Depending on the implementation chosen, you will either need to generate a specific application password (as Gmail and Outlook.com already do for accounts protected by two-step verification), or validate the connection via an authentication app like FranceConnect+ or a SMS code.
For users configuring Convergence on their devices today, this means two things. First, note down the procedure used somewhere, as it will likely need to be repeated when MFA is activated. Second, favor email clients that are regularly updated, capable of handling the OAuth2 protocols that generally accompany MFA.
The transition to MFA will not make daily configuration more complex, but the transition phase will require reconfiguring each device once. Keeping your applications and operating system up to date remains the best preparation for this upcoming change.
