Symptoms

Assume that you're using Microsoft Outlook to either reply to a message or forward a message that's sent from one of the following environments:

  • Microsoft Exchange Server 2013

  • Microsoft Exchange Server 2010 Service Pack 1 (SP1) or Exchange Server 2010 Service Pack 2 (SP2)

  • Microsoft Exchange Online in Office 365

In this situation, Japanese double-byte character set (DBCS) characters that appear in any of the following fields of the message become corrupted:

  • The display name of the sender

  • The display name of the recipients

  • The subject of the message

  • The file name of an attachment

  • The message body

This issue occurs if the field contains single-byte Kana characters.

Note This issue also occurs in posted items in public folders.

Cause

This issue occurs because the value of the PR_INTERNET_CPID MAPI property of the message is stamped as 50222 by Exchange RPC Client Access service or Outlook Web App. Because of a restriction in Outlook, the code page 50222 characters are corrupted.

Resolution

To resolve this issue, use one of the following methods, as appropriate for your situation.

Use the Exchange Management Shell to change the value of the PreferredInternetCodePageForShiftJis parameter to 50220. To do this, follow these steps:

  1. Open the Exchange Management Shell.

  2. Run the following commands:

    Set-OrganizationConfig -PreferredInternetCodePageForShiftJis:50220 
    Get-RemoteDomain | Set-RemoteDomain -PreferredInternetCodePageForShiftJis:50220 


Upgrade to Exchange Server 2010 Service Pack 2 (SP2) and then install the following update rollup:
