SYMPTOMS
When you install the Microsoft Operations Manager (MOM) 2005 Exchange Management Pack on a computer that is running Microsoft Exchange, the following symptoms may occur:
 * Alert rules that are configured to send e-mail notifications to Exchange administrators do not generate the e-mail notifications.
 * The Disk Write Latencies > 50 msec and Disk Read Latencies > 50 msec performance rules do not work correctly. For example, when the sum of the disk latencies for all the attached disks surpasses the 50-millisecond (msec) threshold, an alert is sent. The sum of the latencies for all disks may surpass the 50-msec threshold on a busy Exchange server or on an Exchange server that has many hard disks.
 * The Outlook Mobile Access: Last response time > 60 sec performance rule does not take effect when the Microsoft Outlook Mobile Access client response time exceeds 60 seconds.



CAUSE
These problems occur for the following reasons:
 * The Notification sent to Exchange administrators if severity level is &quot;Error&quot; or higher rule that is contained in the Exchange Management Pack may not reference the correct rule groups. The problem may also occur when this alert rule references a rule group that has a GUID ID of NULL. When this problem occurs, alerts that are generated by this alert rule may not correctly generate e-mail notifications.
 * The Disk Write Latencies > 50 msec and Disk Read Latencies > 50 msec rules do not work correctly because, by default, these performance rules are triggered when the sum of all the latencies for all disks surpasses the 50-msec threshold. The rules should trigger only if the latency of a single disk surpasses 50 msec.
 * The Outlook Mobile Access: Last response time > 60 sec rule does not work correctly because the value in the Generate an alert when the average meets the following condition check box in the Threshold Rule Properties dialog box must be entered in milliseconds. For example, to set a 60-second threshold time, you must enter 60000 in the Generate an alert when the average meets the following condition check box.



RESOLUTION
To make sure that the Exchange Administrators receive e-mail notifications, add the name of the rule group that contains the alert rule in the Alert Rule Properties dialog box. To do this, follow these steps:
 * 1) Log on to the MOM Management Server or on to a computer that has the MOM consoles installed. Use an account that has administrative credentials.
 * 2) Click Start, click Programs, click Microsoft Operations Manager 2005, and then click Administrator Console.
 * 3) In the MOM Administrator console, expand Microsoft Operations Manager , expand Management Packs, expand Rule Groups, expand Microsoft Exchange Server, and then expand the Exchange component that is not sending the alert.
 * 4) Click Alerts, and then double-click the Notification sent to Exchange administrators if severity level is &quot;Error&quot; or higher alert.
 * 5) In the Alert Rule Properties dialog box, click the Alert Criteria tab, click to select the Only match alerts generated by this rule group check box, and then click OK.

To make sure that the Disk Write Latencies > 50 msec and Disk Read Latencies > 50 msec rules do not send alerts when the sum of all the disk latencies surpasses 50 msec, add the Instance not equals _Total criteria to the performance rule. To do this, follow these steps:
 * 1) Log on to the MOM Management computer or on to a computer that has the MOM consoles installed. Use an account that has administrative credentials.
 * 2) Click Start, click Programs, click Microsoft Operations Manager 2005, and then click Administrator Console.
 * 3) In the MOM Administrator console, expand Microsoft Operations Manager , expand Management Packs, expand Rule Groups, expand Microsoft Exchange Server, expand Exchange 2000, expand Server Health Monitoring, expand Server Performance Thresholds, and then click Performance Rules.
 * 4) Double-click Disk Write Latencies > 50 msec.
 * 5) In the Threshold Rule Properties dialog box, click the Criteria tab, and then click Advanced.
 * 6) In the Advanced Criteria dialog box, type Instance not equals _Total in the Value: box, click Add to List, click Close, and then click OK.

To make sure that an alert is sent when the Outlook Mobile Access response time exceeds 60 seconds, change the threshold setting from 60 msec to 60,000 msec. To do this, follow these steps:
 * 1) Log on to the MOM Management computer or on to a computer that has the MOM consoles installed. Use an account that has administrative credentials.
 * 2) Click Start, click Programs, click Microsoft Operations Manager 2005, and then click Administrator Console.
 * 3) In the MOM Administrator console, expand Microsoft Operations Manager , expand Management Packs, expand Rule Groups, expand Microsoft Exchange Server, expand Microsoft Exchange Server 2003, expand Health Monitoring and Performance Thresholds, expand Server Performance Thresholds, and then click Performance Rules.
 * 4) Double-click Outlook Mobile Access: Last response time > 60 sec.
 * 5) In the Threshold Rule Properties dialog box, click the Threshold tab. Type 60000 in the box in the Generate an alert when the average meets the following condition section, and then click OK.
