In this blog post, a virtualization and storage expert encounters a problem with Exchange 2010 disconnections and delivery delays in various global offices. He investigates and resolves the issue by modifying the default throttling policy and failing over DAG volumes to one server that did not have the problem. However, the expert notes that there is still no official explanation from Microsoft regarding the cause of the issue, despite researching Windows updates and the KB2393802 patch.

The post provides a detailed account of the troubleshooting process, including the discovery of Event ID 2915 on CAS servers, the correlation with the default throttling policy, and the use of PowerShell to modify the policy temporarily. The expert also describes how he tested the solution by sending test messages and disabling cache mode on Outlook clients to confirm that the problem was resolved on the server side.

The post highlights the expertise of the author in both virtualization and messaging technologies, as well as their willingness to share their findings and seek further understanding from readers. Additionally, it underscores the importance of keeping up-to-date with Windows updates and actively troubleshooting issues as they arise to ensure optimal performance and reliability in a datacenter environment.

This blog post would be beneficial to anyone working with Exchange 2010 or other messaging technologies, as well as those interested in virtualization, storage, and troubleshooting techniques. By sharing their experience and knowledge, the author demonstrates the value of collaboration and continuous learning within the IT community.
