The webmail of the Dijon academy is based on a centralized portal, the PIA, which provides access to email and several dozen digital services with a single username/password pair. Understanding the technical connection parameters (protocols, servers, ports) helps save time and avoid recurring issues faced by staff, especially at the beginning of the school year.
IMAP settings for Dijon academy webmail: technical data
Configuring an external email client (Thunderbird, Android or iOS app) requires entering specific parameters. The academic server used for incoming mail is hermes.ac-dijon.fr, via the IMAP protocol.
The username to be entered takes the form of firstname.lastname or the short alias (initial + last name), depending on the field requested by the email client.
The choice of the IMAP protocol (and not POP) is the official recommendation. IMAP synchronizes messages across all devices, while POP downloads emails to a single device and may delete them from the server.
For those who wish to connect to the Dijon academy webmail directly from a browser, access is via the PIA portal (pia.ac-dijon.fr) with the same username.
Dijon academic username: formation rules and special cases
The email username follows a strict logic. It consists of the first letter of the first name followed by the last name, all in lowercase and without accents. Jean Dupond becomes jdupond.
Three situations complicate this simple rule:
- Homonyms are assigned a number added to the username (jdupond1, jdupond2). This number appears in the incoming mail or in the information provided by the school’s administration.
- Compound names use a hyphen between the particles. Jean Le Dupond becomes jle-dupond. Omitting the hyphen results in a systematic connection failure.
- The complete email address can take the form [email protected], but the login username for the portal remains the short alias (initial + last name), not the full address.
This distinction between the email address and the login username is a frequent source of confusion. Typing the full address in the PIA username field results in access denial without an explicit error message.
Password initialization with the INA code: procedure for newcomers
Newly assigned staff in the Dijon academy do not yet have an active password. Initialization must go through the INA code, a temporary code provided in a paper letter upon arrival at the institution.
From the PIA authentication page, the “I initialize my password” link opens a form that requests this INA code. Once the password is set, the INA code becomes unusable.
Lost password or locked account
The official sources of the academy direct to the school’s administration to submit a request to the IT service center. The administration remains the sole point of contact for unlocking an account.
This centralized operation implies a variable processing time. Anticipating the verification of access before a busy period (start of school, class councils) helps avoid being without email at a critical moment.
PIA portal and webmail access: what single sign-on really opens
A single authentication provides access to email, calendar, I-Prof, and national applications via the ARENA portal. In practice, once logged in, switching to Chorus DT (expense reimbursements), Magistère (training), or the document space requires no additional entry of credentials.
This architecture is based on a SSO (Single Sign-On) principle. Connecting from an external client like Thunderbird does not benefit from this mechanism: it uses the IMAP protocol described above and requires separate authentication at each launch if the password is not saved.
Mobile access and settings
On an Android smartphone configured in IMAP, the system offers to choose the frequency of checking the inbox. Adjusting this setting allows for a balance between responsiveness and battery life.
Enabling SSL/TLS encryption in the client settings ensures the security of exchanges between the phone and the academic server. Accepting all certificates may be necessary on some devices, but this option reduces the level of verification of the server’s identity.
The academic email of Dijon operates on a stable infrastructure, accessible from a browser or a dedicated client. The main friction point remains the management of usernames, particularly for compound names and homonyms. Checking the exact alias with the administration before any first connection attempt remains the most reliable way to avoid unnecessary blocking.
