Symptoms

Consider the following scenario:
  • You are in an environment that has Microsoft Exchange Server 2010 Service Pack 1 (SP1) or a later update rollup installed.
  • You import an American National Standards Institute (ANSI) format personal folder (.pst) file to a mailbox by running the New-MailboxImportRequest cmdlet.
  • The .pst file contains non-ASCII characters.
  • You open the imported file.
In this scenario, you find some MAPI property objects in the imported file contain unreadable characters. For example, the imported folder names are unreadable.

Cause

This issue occurs because the Microsoft Exchange Mailbox Replication service cannot find a correct code page for the conversion of PT_STRING8 MAPI properties.

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
