This will also affect Goodlink users. In line with Microsoft's Security Update Advisor monthly patch update (http://www.microsoft.com/technet/security/bulletin/advance.mspx), they have plans on releasing a patch on May 9, 2006 for Exchange 2000 Server and Exchange Server 2003. If you are planning on installing this update, it's important to note that this update affects user mailbox permissions by revoking the 'Send As' permission in Exchange which has an impact on third party products such as BlackBerry Enterprise Server for Microsoft Exchange. Once applied, this update will prevent users on BlackBerry Enterprise Server from sending email from a BlackBerry or BlackBerry-enabled device. Recommended Resolution RIM, in conjunction with Microsoft, has provided configuration settings that must be implemented to enable BlackBerry users to continue sending messages. Microsoft is recommending modifying permissions in Active Directory as outlined in the following public-facing Microsoft KBA: http://support.microsoft.com/kb/912918 BlackBerry Technical Support Knowledge Base Article with general information about this change can be found here: http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/ 8021/8149/8064/Support_-_User_cannot_send_messages_because_the_Send_As_p ermission_has_been_revoked.html?nodeid=1166052&vernum=8 Before applying this Microsoft Software Update, RIM recommends that Administrators review these two Knowledge Base articles and take any necessary steps appropriate for their environment.
