XCLN: Outlook & Exchange One-Off SMTP Address & Display Name Parsing |
The information in this article applies to:
-
Microsoft Outlook Windows 95/98 client, versions 8.0, 8.01, 8.02, 8.03, 8.5
-
Microsoft Outlook Windows NT client, versions 8.0, 8.01, 8.02, 8.03, 8.5
-
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:
<someone@microsoft.com>
First Last <someone@microsoft.com>
(First Last) <someone@microsoft.com>
"First Last" <someone@microsoft.com>
(First Last) someone@microsoft.com
"First Last" someone@microsoft.com
First Last <"<First>Last"@microsoft.com>
(First Last) "<First>Last"@microsoft.com
someone@microsoft.com (First Last)
someone@microsoft.com "First Last"
<someone@microsoft.com> (First Last)
<someone@microsoft.com> "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 <someone@microsoft.com>
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
<someone@microsoft.com>
First Last <someone@microsoft.com>
(First Last) <someone@microsoft.com>
"First Last" <someone@microsoft.com>
(First Last) someone@microsoft.com
"First Last" someone@microsoft.com
First Last <"<First>Last"@microsoft.com>
(First Last) "<First>Last"@microsoft.com
"First Last" "<First>Last"@microsoft.com
someone@microsoft.com (First Last)
someone@microsoft.com "First Last"
<someone@microsoft.com> (First Last)
<someone@microsoft.com> "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 <someone@microsoft.com>
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
