XADM: Cannot Log On Using IMAP4 If WinNT Locale Set to Swedish or Norwegian

ID: Q182618

The information in this article applies to:

Microsoft Exchange Server, version 5.5

SYMPTOMS

An IMAP4 e-mail client cannot log on to a Microsoft Exchange Server 5.5 computer if the Windows NT default locale is set to Swedish. (The default locale is set in the Control Panel Regional Settings.)

If you enable protocol logging for IMAP4, you will see that the IMAP4 session fails when the client issues the LOGIN command:


   01/26/1998 17:31:43.079     (TID:141): IMAP connection accepted from
   157.58.35.128
   01/26/1998 17:31:43.139 >>> (TID:141): * OK Microsoft Exchange IMAP4rev1
   Server Ready
   01/26/1998 17:34:05.003 <<< (TID:141): 1 LOGIN U116BIT password
   01/26/1998 17:34:05.193 >>> (TID:141): 1 NO

However, if the Windows NT locale is set to English, the same login will work correctly:


   01/26/1998 16:54:39.267     (TID:140): IMAP connection accepted from
   157.58.35.128
   01/26/1998 16:54:39.267 >>> (TID:140): * OK Microsoft Exchange IMAP4rev1
   server version 5.5.2147.0 (JUNWIN03) ready
   01/26/1998 16:54:55.370 <<< (TID:140): 1 LOGIN U116BIT PASSWORD
   01/26/1998 16:54:55.520 >>> (TID:140): 1 OK LOGIN completed.

CAUSE

The Exchange Information Store service does not correctly handle the IMAP4 responses to the client if the locale is not set to English, French, German, or Japanese.

WORKAROUND

To work around this problem, set the locale to English, French, German, or Japanese. If that is not possible, a fix for this problem is now available.

NOTE: After you apply this fix, portions of the return message will be in the same language as the Windows NT locale.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.5. This problem has been corrected in the latest U.S. Service Pack for Microsoft Exchange Server version 5.5.
