A factor who changes their site affiliation, a newly recruited parcel agent who does not yet have their HR identifier, a support functions manager who encounters a login page different from the previous day: the choice of the access portal to GTm Extranet La Poste is not trivial. Behind the names MaBoxRH, GTm Extranet, or Group portal, there are distinct access paths that depend on the profile, the network used, and the level of authorization.
Intranet access or Google search: two paths, two levels of risk
On a workstation connected to the La Poste internal network, the recommended route goes through the business intranet portal (Safir or the HR applications page). This path automatically redirects to GTm Extranet without typing a URL into a search engine. This way, we avoid fake portals and phishing pages that specifically target queries like “GTA La Poste” or “GTm extranet”.

From a personal computer or a smartphone outside the network, the only reliable address remains maboxrh.laposte.fr. Internal guides present Google search as a backup solution, not as the primary reflex. Checking the domain in the address bar before entering anything remains the basic precaution.
The distinction matters because several phishing campaigns exploit URL variants close to the official name. A bookmark saved in the browser or a shortcut on the phone’s home screen is enough to avoid searching for the link at each login. This habit is recommended from the first use to manage access to GTA Extranet La Poste without any unpleasant surprises.

HR identifier or group.net account: knowing which one to use to log in
The gradual switch to authentication via the Group directory (account “groupe.net”) complicates matters. Depending on the business scope, some agents first log in through a corporate portal before being redirected to MaBoxRH, while others still use their HR identifier directly on the GTm Extranet login page.
The correct identifier depends on the branch and the account’s seniority. A historical mail agent often retains their classic HR identifier. An employee assigned to a subsidiary recently integrated into the Group scope may be assigned a group.net account upon hiring.
In case of doubt, the local HR remains the quickest contact. Technical support ([email protected]) handles access blockages, but does not manage questions related to portal choice or the type of identifier. The distinction between the two channels saves time.
New hires and onboarding paths on GTm Extranet
Agents who have just taken their positions do not always have an active HR identifier from day one. Specific onboarding paths exist around GTm Extranet and MaBoxRH, with guides dedicated to managing time, schedules, and absences.
The common problem: you receive an employee number, but the activation of the account on MaBoxRH takes a few days. During this window, it sometimes happens that a colleague lends their access or that one tries to log in repeatedly. Neither of these works. Account activation requires a non-compressible technical delay after the creation of the administrative file.
Once the account is active, the first useful reflex is to:
- Set up the security question and backup email address on the password reset page, so as not to depend on support in case of forgetting
- Test access to the virtual keyboard on the authentication page, which can be disorienting during the first login (the password numbers are entered by clicking, not on the physical keyboard)
- Check that the schedule and leave rights are displayed correctly, as a poorly linked file can return a blank page without an explicit error message
Virtual keyboard and accessibility
The virtual keyboard of MaBoxRH serves as protection against spyware that records keystrokes. For visually impaired or blind agents, an audio version is available: you must activate the “Enable audio” button located before the keyboard, then navigate with the tab key to browse the numbers and validate each entry with the Enter key.
Feedback varies on this point: some agents find the system reliable with JAWS or NVDA, while others report latencies depending on the browser used. Testing with the workstation’s screen reader before regular use allows for anticipating adjustments.
MaBoxRH, GTm Extranet, and smart portal: untangling the ongoing convergence
MaBoxRH and GTm Extranet practically refer to two layers of the same service. GTm Extranet is the technical foundation (time and activity management). MaBoxRH is the visible interface for the agent, where pay slips, leave, and administrative files are consulted.
The ongoing convergence between MaBoxRH, GTm Extranet, and the smart portal has reshaped the consultation paths. Specifically, some functionalities that were previously accessible directly from GTm Extranet now require going through MaBoxRH, and vice versa. Keeping both addresses in favorites avoids going in circles when a redirection does not work.
Personal data, schedules, and leave rights remain accessible, but the path to reach them changes according to portal updates. An agent who can no longer find a section has every interest in checking if they are indeed on MaBoxRH (maboxrh.laposte.fr) rather than on an outdated internal URL.
- For pay slips and the administrative file: MaBoxRH is the main entry point
- For schedules and time management: GTm Extranet remains the engine, but access is mostly through MaBoxRH
- For leave or absence requests: entry is through the same portal, with validation by the hierarchical manager
The address maboxrh.laposte.fr remains the unique reference point for external access. When in doubt between several portals, this is the one to prioritize, ensuring that the displayed domain corresponds to laposte.fr. The rest, whether it is the name GTm Extranet in the browser tab or the GTA logo on the login page, pertains to the technical dressing of the same tool.
