XFOR: Attachment with PC Binary or PC ASCII Flag Set Unreadable (181280)


The information in this article applies to:

  • Microsoft Exchange Server 4.0
  • Microsoft Exchange Server 5.0
  • Microsoft Exchange Server 5.5
  • LinkAge Message Exchange 3.2
This article was previously published under Q181280

SYMPTOMS

An attachment of type PC Binary or PC ASCII that is sent from IBM Office Vision (PROFS and/or OV/VM) to Exchange via the Linkage Message Exchange OV/VM Connector version 3.2 is unreadable in Exchange.

CAUSE

An attachment with the PC Binary or PC ASCII flag set is transformed per entries in the Conversational Monitor System (CMS) to Exchange mapping table (Cmsxmap.tbl). This behavior is incorrect; messages with PC Binary or ASCII flags set do not need conversion and should be sent right through to Exchange. This conversion strips the first two characters, resulting in an unreadable attachment.

RESOLUTION

Apply the fix described below. The Linkage Message Exchange OV/VM connector was fixed to not read the Cmsxmap.tbl when the PC Binary or PC ASCII flags are detected on an attachment coming down from the host.

STATUS

Microsoft has confirmed this to be a problem in Linkage Message Exchange version 3.2.

A supported fix is now available, but has not been fully regression-tested and should be applied only to systems experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft recommends that you wait for the next Service Pack that contains this fix. Contact Microsoft Technical Support for more information.


MORE INFORMATION

When storing CMS files to OV/VM storage, note that PC Binary should only apply to PC Binary files (for example, *.doc, *.xls) without EBCDIC conversion, and PC ASCII should apply to PC text files uploaded to the host with EDCDIC conversion.
