SYMPTOMS
When attempting to log on to a Microsoft Exchange Server mailbox from a Microsoft Exchange for Macintosh client, you may receive the following error message:

The logon credentials supplied were incorrect. Make sure

your username and domain are correct, then type your

password again.



CAUSE
This error may occur if the Windows NT user account specified contains extended characters that are not mapped correctly from the Macintosh character set to the Windows ANSI character set.



WORKAROUND
When creating Windows NT user accounts, avoid using extended characters (for example, A-umlaut or E-umlaut) in the user name.

NOTE: An umlaut appears as two dots placed above a vowel.



STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange for the Macintosh, versions 4.0 and 5.0. This problem was corrected in the latest Microsoft Exchange Server 5.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

MORE INFORMATION
This behavior may be seen when using foreign languages that have extended characters in their alphabet.
