The PIAL portal of the Nancy-Metz academy and its successor Partage share the same centralized authentication system. The username remains the one used for iProf, and the initial password corresponds to the NUMEN. Any difficulty in connecting to the academic messaging system is resolved by precisely identifying the cause of the blockage before attempting any corrective action.
Diagnosis of the blockage according to the error message displayed on the PIAL Nancy-Metz portal
An authentication refusal on the portal does not always mean the same thing. Three distinct situations produce a failure screen, and each calls for a different response.

A message indicating incorrect credentials points to an incorrect or expired password. The default password is the NUMEN, and if you have never changed it, this is the first avenue to check with your IEN. A modified password that has been forgotten can be reset via the “Forgot Password” link on the login page.
A message indicating a locked account signifies a security blockage, usually triggered after several unsuccessful attempts. In this case, resetting the password is not enough: you must go through the unlocking procedure available on the academy’s identifier portal.

The third case, more common than one might think: you are trying to log in on the wrong portal. Since the migration to Partage, the old PIAL URLs sometimes redirect inconsistently. If the page displays an error like “service unavailable” or a redirection loop, check that you are using the address login.ac-nancy-metz.fr and not an old bookmark pointing to pial.ac-nancy-metz.fr.
We recommend proceeding systematically in this order: check the URL, then test the password, then unlock the account. A detailed guide on PIAL Nancy Metz authentication allows you to follow each step visually.
Resetting and unlocking an account at the Nancy-Metz academy
The password reset page and the unlocking page are accessible from the same URL of the academic identifier portal. However, the two procedures are not interchangeable.
Expired or forgotten password
The reset sends a temporary link to a backup address that you provided during your initial activation. If this address has never been configured, the online procedure fails silently. You then need to go through support.
Without a configured backup address, no autonomous reset is possible. This is a point that most online guides overlook. We observe that many agents have never provided this address when starting their position.
Account locked after multiple attempts
The lock can be lifted via the same page, but the option displayed differs. You must select “Unlock your account” and not “Forgot Password.” Confusing the two procedures generates a new password on an account that is still locked, prolonging inaccessibility.
- Message “incorrect credentials”: use “Forgot Password” to generate a new password via your backup address.
- Message “account locked”: use “Unlock your account,” which reactivates access without changing the existing password.
- Redirection loop or blank page: clear your browser cache, check the URL (login.ac-nancy-metz.fr), and try again without an active VPN.
IMAP configuration and webmail access to the academic messaging system
Once authentication is successful, access to the messaging system is either through the webmail integrated into Partage or through a mail client configured in IMAP.
The webmail is accessible directly from the Partage intranet after logging in. For daily use on Outlook or Thunderbird, the IMAP server to be provided is that of the Nancy-Metz academy, with secure port and authentication by academic identifier (not by full email address on some clients).
A common pitfall: Thunderbird attempts to automatically detect server settings from the address in @ac-nancy-metz.fr. This autodiscovery regularly fails because the domain does not publish a standard SRV configuration. We recommend forcing manual configuration from the start to avoid synchronization errors in the inbox.
Parameters to check as a priority
- Login identifier: your academic identifier (first.last or variant with initial), never the full email address on some clients.
- Protocol: IMAP with SSL/TLS encryption. The POP3 protocol works but does not synchronize folders between devices.
- Authentication: normal password, no OAuth2 (not supported by the academic server).
Academic support: open a ticket when the reset fails
If the online reset and unlocking do not resolve the issue, the Nancy-Metz academy requires going through a support ticket opened from the Partage intranet. This is a real point of friction: to contact support, you must be logged into the tool you cannot access.
The official solution is to ask a colleague already logged into Partage to open the ticket on your behalf. The academy recognizes this delegation procedure. The ticket must mention your academic identifier, the exact error message displayed, and the browser used.
No direct phone number is documented for this type of request. The only channel remains the ticket via Partage, making the colleague backup procedure not optional but structurally necessary for agents who are completely blocked.
The processing time depends on the period: at the beginning of the school year, reset requests saturate the service. Configuring your backup address as soon as you log in for the first time remains the best prevention against prolonged blockage of access to the academic messaging system.
