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.
