APPLIES TO

SYMPTOMS
When you try to access a Microsoft Exchange Server 2003 computer by using Outlook Mobile Access (OMA), you cannot successfully connect.



CAUSE
This behavior may occur if both of the following conditions are true for Outlook Mobile Access connections:
 * The Exchange Server 2003 computer is configured to require Secure Sockets Layer (SSL).
 * The Exchange Server 2003 computer is configured to use a GTE CyberTrust certification authority (CA).

Some handheld devices do not contain a certificate for GTE CyberTrust. Because of this, they cannot use Outlook Mobile Access to successfully connect to the Exchange Server 2003 computer when a GTE CyberTrust certificate is required.



MORE INFORMATION
This behavior is known to occur on some KDDI and NTT DoCoMo, Inc. mobile phones when a GTE CyberTrust certification authority is used.
