Assume that you have a Microsoft Exchange Server 2010 Service Pack 2 (SP2) organization that is monitored by a System Center Operations Manager (SCOM) server. You install the Exchange Server 2010 SP2 version of the Exchange Server 2010 Management Pack on the SCOM server. In this situation, many mailboxes in a single mailbox database are quarantined. Additionally, the following event is logged in the Application log on the Mailbox server:
Log Name: Application
This issue occurs because the SCOM server uses the Troubleshoot-DatabaseSpace.ps1 script to monitor log generation. The mailboxes are quarantined because the script is executed when there is less than 25 percent of free disk space. Additionally, the mailboxes are quarantined when the JET Log Bytes Generated/hour performance counter indicates that the log generation consumes the remaining free disk space within 12 hours.
Note The default settings that are used in the Troubleshoot-DatabaseSpace.ps1 script are defined in the StoreTSConstants.ps1 script that is located in the following path:
Drive:\Program Files\Microsoft\Exchange Server\V14\Scripts\StoreTSConstants.ps1
