DOCUMENT:Q184957 03-APR-2001 [exchange] TITLE :XCLN: Outlook & Exchange One-Off SMTP & Display Name Parsing PRODUCT :Microsoft Exchange PROD/VER::8.0,8.01,8.02,8.03; WINDOWS:4.0,5.0 OPER/SYS: KEYWORDS:exc55sp2fix ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Outlook 97, versions 8.0, 8.01, 8.02, 8.03 - Microsoft Outlook 98 - Microsoft Exchange Windows 95/98 client, versions 4.0, 5.0 - Microsoft Exchange Windows NT client, versions 4.0, 5.0 - Microsoft Exchange Windows 3.x client, versions 4.0, 5.0 ------------------------------------------------------------------------------- SYMPTOMS ======== Microsoft Exchange and Outlook clients are unable to parse one-off SMTP addresses in the following forms: First Last (First Last) "First Last" (First Last) someone@microsoft.com "First Last" someone@microsoft.com First Last <"Last"@microsoft.com> (First Last) "Last"@microsoft.com someone@microsoft.com (First Last) someone@microsoft.com "First Last" (First Last) "First Last" CAUSE ===== Microsoft Exchange clients and Microsoft Outlook 97 client versions 8.00, 8.01, 8.02, and 8.03 only accept one-off SMTP addresses in the form of: someone@microsoft.com Microsoft Outlook 98 version 8.50 accepts one-off SMTP addresses in the following forms: someone@microsoft.com First Last Outlook 98 parses the SMTP address from the one-off string in the last example above, but it uses the full original string as the display name. WORKAROUND ========== Use the one-off SMTP addressing forms supported by the Outlook and Exchange clients. RESOLUTION ========== To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For more information, please see the following article in the Microsoft Knowledge Base: Q191014 XGEN: How to Obtain the Latest Exchange Server 5.5 Service Pack Additional SMTP one-off address parsing features are now available from Microsoft as an official hotfix for Outlook and Exchange clients. Contact Microsoft Technical Support for more information. STATUS ====== Microsoft has confirmed this to be a problem in the products listed above. 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. This problem was first corrected in Exchange Server 5.5 Service Pack 2. MORE INFORMATION ================ Microsoft Exchange and Outlook clients can parse one-off SMTP addresses and display names in the following forms when you apply the hotfix: someone@microsoft.com First Last (First Last) "First Last" (First Last) someone@microsoft.com "First Last" someone@microsoft.com First Last <"Last"@microsoft.com> (First Last) "Last"@microsoft.com "First Last" "Last"@microsoft.com someone@microsoft.com (First Last) someone@microsoft.com "First Last" (First Last) "First Last" These additional addressing forms are only available as one-off addresses. The new parsing code successfully parses the display names and e-mail addresses from the strings. For example, if someone entered the following string as a one-off: First Last it would be parsed as follows: Display Name: First Last E-mail Address: someone@microsoft.com The new parsing functionality only applies to one-off SMTP addresses. PAB SMTP addresses still need to be entered as follows: Display Name: First Last E-mail Address: someone@microsoft.com The new SMTP parsing code is only invoked when an SMTP address has been entered as a one-off on the "TO" line and a "check names" has been performed, or when the Outlook background name check thread is invoked. The Outlook background name check thread is executed when an SMTP one-off address has been entered and the TAB key is selected to advance to the next field. The Outlook background name check thread was designed to remove white space from the one-off string. This was a useful feature for eliminating typos before processing the address. However, this feature needed to be removed, because the clients are now able to parse complex strings and addresses that may contain spaces. The new SMTP one-off parsing functionality was added to Mapi32.dll. The Outlook background name check function was modified in Outllib.dll. These were separate modifications, but both should be implemented when using the Outlook client. If the Outllib.dll is not updated, the display name will be parsed without a space and will appear as: Display Name: FirstLast E-mail Address: someone@microsoft.com Additional query words: 8.5 ====================================================================== Keywords : exc55sp2fix Technology : kbOutlookSearch kbExchangeSearch kbExchange500 kbExchange400 kbExchangeClientSearch kbZNotKeyword kbOutlook97 kbZNotKeyword2 kbOutlook97Search kbOutlook98Search kbZNotKeyword3 kbOutlook801 kbOutlook802 kbOutlook803 kbExchange400NT kbExchange500NT kbExchange400Win95 kbExchange500Win95 Version : :8.0,8.01,8.02,8.03; WINDOWS:4.0,5.0 Issue type : kbbug Solution Type : kbfix ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
