XCLN: Cannot Resolve SMTP Addresses, Messages Sent Successfully

• Microsoft Exchange Windows NT client, version 5.0
• Microsoft Exchange Windows 95 client, version 5.0
• Microsoft Outlook Windows NT client, versions 8.01, 8.02, 8.03
• Microsoft Outlook Windows 95 client, versions 8.01, 8.02, 8.03

SYMPTOMS

When you address a message to a Simple Mail Transfer Protocol (SMTP) recipient that is located in your personal address book (PAB) or the global address list, the SMTP address may not be resolved. Your e-mail client may underline the SMTP address and send the message successfully, but the address is not resolved to the display name that appears in the PAB or global address list.

CAUSE

This problem can occur when one or more of the following files are damaged:

• Emsabp32.dll
• Emsui32.dll
• Mapi32.dll
• Wmsui.dll
• Wmsui32.dll

WORKAROUND

To resolve this problem, verify that the above files are not damaged. To do so, use one of the following methods:

• If you are using a Microsoft Exchange client, rename the files on your hard disk, and then extract new copies of the files from the Microsoft Exchange 5.0 Client Pack CD-ROM. The following table lists the location of the files on the CD-ROM:

        File           Cabinet File
        ---------------------------
        Emsabp32.dll   Exchng4.cab
        Emsui32.dll    Exchng4.cab
        Mapi32.dll     Exchng5.cab
        Wmsui.dll      Exchng7.cab
        Wmsui32.dll    Exchng8.cab
  
     NOTE: Windows 95 cabinet files are located in the Eng\Win95 folder on
     the CD-ROM. Windows NT (Intel) cabinet files are located in the
     Eng\Winnt\I386 folder on the CD-ROM.
  
  

• If you are using a Microsoft Outlook client, rename the files on your hard disk, and then copy the files from the Outlook CD-ROM to your hard disk.
• Reinstall your e-mail client.
