Explanation

This Error event indicates that the Microsoft® Exchange System Attendant service cannot start because one or more tasks of this service are blocked. The function name that is specified in the event description indicates the blocked task. Each blocked task will cause this event to be logged by having the function name in the event description. This event may occur for various reasons. See the "User Action" section for information about how to resolve this error.

User Action

To resolve this problem, do one or more of the following:

• If this Error event is followed by MSExchangeSA Informational Event ID 1032 that has the same function name as specified in the event description, this indicates that a blocked task has recovered from a long delay and now operates correctly.

• If this event occurs repeatedly without an MSExchangeSA Event ID 1032, increase the diagnostic logging level on the following counters of the MSExchangeSA performance object for additional events:

  • NSPI Proxy

  • OAL Generator

  • Proxy Generation

You can increase logging by running the following Exchange Management Shell commands:

• Set-EventLogLevel "MSExchangeSA\NSPI Proxy" -Level High

• Set-EventLogLevel "MSExchangeSA\OAL Generator" -Level High

• Set-EventLogLevel "MSExchangeSA\Proxy Generation" -Level High

For detailed information about how to increase logging, see Manage Diagnostic Logging Levels.

• Review other related Error events and Warning events that are logged in the Application log. These related events may help you find the root cause of this error.

• Try to restart Microsoft Exchange System Attendant service from the Services panel.

Important After you finish troubleshooting this problem, return logging to the default level by running the following commands:

• Set-EventLogLevel "MSExchangeSA\NSPI Proxy" -Level Lowest

• Set-EventLogLevel "MSExchangeSA\OAL Generator" -Level Lowest

• Set-EventLogLevel "MSExchangeSA\Proxy Generation" -Level Lowest
