Folder names are incorrect or displayed in an incorrect language in Outlook

Symptoms

You experience the following issues that affect folder names in Microsoft Outlook:

  • Folder names appear in a language other than the default language.

    Note

    This issue occurs if a mobile device or a third-party server application synchronizes the Exchange Server mailbox. To resolve this issue, try Method 1 first. If that doesn't work, try Method 2 or 3.

  • Folder names are changed unexpectedly (for example, the Inbox folder and the Outbox folder are switched).

    Note

    This issue may occur after Exchange Server mailbox maintenance. To resolve this issue, try Method 1 first. If that doesn't work, try Method 2 or 3.

    Or, the default Inbox folder is changed unexpectedly to Archive in Exchange Online. To resolve this issue, try Method 4.

  • Folder names are no longer correct after you run the Outlook.exe /ResetFolderNames command to reset the default folder names.

    Note

    To resolve this issue, try Method 2 or 3.

For more information about how to run outlook.exe with the command-line switches, see Command-line switches for Outlook for Windows.

To fix the issues, use one or more of the following methods.

Method 1

Use the /resetfolders switch to restore missing folders at the default delivery location. To do this, follow these steps:

  1. Exit Outlook.
  2. Run Outlook.exe /resetfolders.
  3. Run Outlook.exe /resetfoldernames.

Method 2

Use Outlook Web App to reset the default folder names:

  1. Exit Outlook.

  2. Log on to Outlook Web App by using your credentials.

  3. Select Settings (the gear icon on the right) > Options > General (expand the list in the navigation pane) > Language and time.

  4. On the Language and time page, change the language, select the date and time format that you want to use, select the Rename default folders so their names match the specified language option, and then select Save.

  5. Exit Outlook Web App.

    Note

    If your preferred language is already selected, you may have to select any other language, save the setting, reset the setting to your preferred language, and then save the setting again.

  6. Restart Outlook.

Method 3

If you're 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 Set-MailboxRegionalConfiguration cmdlet, see Set-MailboxRegionalConfiguration.

Option 1 (preferred)

Use Outlook to select a new Archive folder. To do this, follow these steps:

  4. Expand Root Container, and then expand Top of Information Store (if the user has the mailbox set to a language other than English, then the name of this folder will be translated).
  5. Select the new Archive01 folder, and then find the property that's named PR_ENTRYID.
  6. Double-click to open the PR_ENTRYID property, and then copy the property binary value.
