The Calendar Checking Tool for Outlook is a command-line program that checks Outlook Calendars for problems. To use this tool, the Outlook calendar must reside on a Microsoft Exchange Server. The tool does not work with IMAP, with POP3, or with other non-Exchange mail servers.

The tool opens an Outlook profile, opens the Outlook Calendar, and then checks several things such as permissions, free/busy publishing, and auto booking. Then, the tool checks each item in the calendar folder for problems that can cause items to seem to be missing or that might otherwise cause problems in the Calendar.

The Outlook Configuration Analyzer Tool provides a detailed report of your current Outlook profile. This report includes many parameters about your profile, and it highlights any known problems that are found in your profile. For any problems that are listed in the report, you are provided a link to a Microsoft Knowledge Base (KB) article that describes a possible fix for the problem. If you are a Help Desk professional, you can also export the report to a file. Then, the report can be viewed in the Outlook Configuration Analyzer Tool on another client computer where the tool is installed.

The Exchange Team blog has published an article recommending all DAG members running Windows 2008 R2 to have a few hotfixes installed. Microsoft has encountered scenarios in which a transient network failure occurs (a failure of network communications for about 60 seconds) and as a result, the entire cluster is deadlocked and all databases are within the DAG are dismounted. Since it is not very easy to determine which cluster node is actually deadlocked, if a failover cluster deadlocks as a result of the reconnect logic race, the only available course of action is to restart all members within the entire cluster to resolve the deadlock condition.

The following KBs list the recommended hotfixes .

• KB2550886- A transient communication failure causes a Windows Server 2008 R2 failover cluster to stop working
• http://support.microsoft.com/kb/2549472 – Cluster node cannot rejoin the cluster after the node is restarted or removed from the cluster in Windows Server 2008 R2
• http://support.microsoft.com/kb/2549448 – Cluster service still uses the default time-out value after you configure the regroup time-out setting in Windows Server 2008 R2
• http://support.microsoft.com/kb/2552040 – A Windows Server 2008 R2 failover cluster loses quorum when an asymmetric communication fail.
