New-MailboxImportRequest causes unreadable characters when you import an ANSI format .pst file of Russian language

Applies to: Exchange Server 2013 EnterpriseExchange Server 2013 Standard Edition


Consider the following scenario:
  • You are in a Microsoft Exchange Server 2013 environment.
  • You import an American National Standards Institute (ANSI) format personal folder (.pst) file of Russian language that has a Cyrillic encoding to a mailbox by running the New-MailboxImportRequest cmdlet.
  • The .pst file contains non-ASCII characters.
  • You open the imported file.
In this scenario, the imported folder names and contents are unreadable. The characters that are used for folder names is a garbled mix of special characters. 


To resolve this issue, install Cumulative Update 7 for Exchange Server 2013.


To work around this issue, import the ANSI .pst file by using Microsoft Outlook or convert the ANSI .pst file to a Unicode file before you run the New-MailboxImportRequest cmdlet.


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