Bonjour,
ce paramètres est défini à la premiere connexion de l'utilisateur:
- At the first connection of a MAPI agent (like Outlook client) to a user mailbox, the language of the default folders (like inbox) and system messages (like quota messages and non-delivery reports) was set on the information store (PR_LOCALE_ID MAPI property)
to the language used by the MAPI agent.
- Each new connection of an MAPI agent changed the PR_LOCALE_ID of the mailbox to match the one used by the agent. Only system messages were modified, the default folders remained in the language of the first agent connection
Essaie de repasser la langue de la boite en francais avec la cmdlet:
Set-Mailbox -Identity "Carlo Dupont" -Languages "fr-FR"
Pour le faire pour toutes tes boites:
Get-Mailbox | Set-Mailbox -Languages "fr-FR"
