The portal partage.ac-strasbourg.fr remains the main entry point for academic messaging for staff at the Strasbourg academy. Connection issues rarely stem from a single cause: outdated IMAP configuration, a favorite pointing to an old portal, a full mailbox quota, or an unidentified national outage. We detail here the technical checks to be carried out in order, from the most targeted to the broadest.
IMAP, SMTP, and SSL port configuration: priority settings to check
The majority of connection failures on an email client (Thunderbird, Outlook, mobile app) arise from incorrect or outdated server settings. The incoming server is an IMAP server with STARTTLS encryption on the dedicated port. The outgoing server uses SMTPS or SMTP with STARTTLS depending on the client configuration.

We recommend checking three points before any other actions:
- The type of encryption selected: SSL/TLS or STARTTLS depending on the configured port. A mix of the two causes a silent rejection of the connection without an explicit error message.
- The provided identifier: the Strasbourg academy accepts the short academic identifier (first letter of the first name followed by the last name, without accents) or the full email address. Using a different format (first.last, for example) blocks authentication.
- The password: after several failed attempts, the account locks. The unlocking procedure goes through the link “Reset your password or unlock your account” on partage.ac-strasbourg.fr, and not through the email client itself.
A point often overlooked: the default mailbox quota is very low. A full mailbox refuses new IMAP synchronizations without always sending a clear error on the client side. The link “Manage your mailbox quota,” accessible from the authentication page, allows you to increase this capacity.

Migration to messagerie.education.gouv.fr: the trap of the wrong portal
Since the start of the 2023-2024 school year, the National Education has initiated a switch to a national professional messaging system accessible via messagerie.education.gouv.fr. The transition is presented as seamless: retention of the address, automatic redirection of flows.
In practice, this migration generates a type of problem that current academic guides do not address. Staff who have updated their favorites to the new national portal but whose accounts have not yet migrated face an authentication refusal. The reverse is also true: an already migrated account attempting to connect to partage.ac-strasbourg.fr may receive an unknown identifier error.
Identifying the correct portal for your account
No simple visual indicator allows you to know if an account has already migrated. The most reliable reflex: test the connection on both portals. If authentication works on messagerie.education.gouv.fr, the account has migrated. Otherwise, stay on partage.ac-strasbourg.fr.
This confusion explains a significant portion of outage reports that are not actual outages. We observe that staff with multiple configured devices (work computer, personal phone, tablet) end up with configurations pointing to different servers after migration.
Server outage or local issue: distinguish between the two in under two minutes
Tracking sites like TotalBug aggregate user reports for the Strasbourg academy. In case of doubt, checking this type of platform before modifying settings helps avoid breaking a functional configuration while trying to resolve a problem that does not exist on the user side.
A simultaneous blockage on webmail and email client indicates a server outage. If webmail works but the client (Thunderbird, Outlook) does not, the problem is local. If neither works, two hypotheses: academic outage or locked account.
Reporting channels to know
The Strasbourg academy publishes a tracking of ongoing messaging alerts on the SSI academic site (ssi.ac-strasbourg.fr). This page is rarely consulted even though it provides the actual status of the service. Social media and Facebook groups for educational staff also relay outages, but with a delay and without official confirmation.
For related applications (SAVA, Colibris), dedicated support addresses exist in the format [email protected]. These contacts are distinct from standard messaging support and are not listed on the main login page.
Recovering AC Strasbourg username and password: procedure without email access
The official procedure for recovering a username goes through the form accessible from partage.ac-strasbourg.fr, section “Know your username.” The form requires first and last name, without accents in the input fields (case does not matter).
The user guide from DSIGE (updated in September 2024) specifies that the academic identifier generally follows the format first letter of the first name + last name concatenated. Cases of duplicates (namesakes) generate variants with added numbers, complicating recovery.
Resetting without access to the recovery address
If the recovery information (personal address, phone number) has never been provided, the online form cannot send the reset link. In this case, only direct contact with the institution’s IT service or the academic DSI can resolve the situation.
The authentication page also offers a link to provide or modify recovery information, but this action requires being logged in. This is a classic vicious circle that the platform does not resolve on its own. Anticipating by providing this information at the first connection remains the only reliable workaround.
