You cannot change the default folder names to another language by using the /ResetFolderNames switch in Outlook

Consider the following scenario:
  • You connect to a Microsoft Exchange Server 2010 mailbox by using Microsoft Outlook.
  • You use the English UI in Outlook, so the default folder names (such as Inbox or Sent Items) are displayed in English.
  • You install a new language pack for Outlook, and then you change the Outlook UI to the new language.
  • You restart Outlook by running the Outlook.exe /ResetFolderNames command to reset the default folder names to the new language.
In this scenario, the folder names are not changed to the new language.

Note This issue does not occur when you use Outlook to connect to a mailbox that is located on a Microsoft Exchange Server 2007 server.
To work around this issue, use one of the following methods.

Method 1

If you are an administrator, run the following cmdlet to reset the default folder names for the user:
set-MailboxRegionalConfiguration -id <alias> -LocalizeDefaultFolderName:$true -Language <Language_code_to_switch_to> -DateFormat <your_preferred_DateFormat>

For more information about the possible language codes and the Set-MailboxRegionalConfiguration cmdlet, go to the following MSDN websites:
Method 2

If you are an end-user, use Outlook Web App to reset the default folder names:
  1. Log on to Outlook Web App by using your credential.
  2. Click Options, and then click See All Options.
  3. Click Settings, and then click Regional.
  4. On the Regional Settings page, change the language, select the date and time format that you want to use, and then select the Rename default folders so their names match the specified language option.
  5. Click Save, and then exit Outlook Web App.
  6. Restart Outlook.
