SYMPTOMS
If a Collaboration Data Objects (CDO 1.21) application runs on a Chinese Traditional (CHT) or Chinese Simplified (CHS) Windows NT system, the Text property of the message may return truncated. For this to occur, the PR_BODY property of the message must be a Multi-Byte Character Set (MBCS) and contain a mix of American National Standards Institute (ANSI) and MBCS characters in the first 255 characters of the message.

The following sample Visual Basic code fragment shows how one might read the Text property of a message object using CDO (1.21):

Set sessionObj = CreateObject("MAPI.Session") sessionObj.logon "TestUser", "TestUser", 0

Set InboxObj = sessionObj.Inbox Set messageCol = InboxObj.Messages Leng = messageCol.Count Set messageFilter = messageCol.Filter messageFilter.Unread = True

Set pMessage = messageCol.GetFirst retv = pMessage.Text

If the preceding conditions are met, when you display retv, it is truncated to the first 255 characters of the message.



CAUSE
A logic problem is preventing CDO (1.21) from detecting that the Text property has been truncated.



RESOLUTION
To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

191014 XGEN: How to Obtain the Latest Exchange Server 5.5 Service Pack

The English version of this fix should have the following file attributes or later:

Component: Collaboration Data Objects (CDO 1.21)

  Version      File name --  5.5.2540.0   Cdo.dll

WORKAROUND
Adding the following line prior to retrieving the Text property as a work around to this problem:

n = pMessage.fields.count



STATUS
Microsoft has confirmed that this is a problem in Collaboration Data Objects version 1.21. This problem was first corrected in Exchange Server 5.5 Service Pack 3.
