Audience: Office 365 for professionals and small businesses Office 365 for enterprises With the release of the Microsoft Online Services Diagnostics and Logging Support Toolkit 4.6 , we introduce a number of exciting new features and improve the user experience yet again so both users (information workers) and administrators can collect the right data, for the right problem. In this release, we made an effort to make the tool and its output, more user friendly. Not only did we make improvements to the UI to help guide users through the data collection process, we made many of the reports that MOSDAL generates more readable. Please read below for additional details on all the improvements MOSDAL 4.6 has to offer: User Interface Changes – Added information to help users collect the right data, as well as understand what data MOSDAL is collecting. New Languages – MOSDAL is now offered in Russian and Korean languages. Smaller download – MOSDAL will only download .NET 4.0 and Windows Installer 3.0 if they are not present on the system. This reduces the size of the installation package by more than half. Exchange ActiveSync diagnostics – In addition to testing the Exchange Autodiscover process, MOSDAL now also performs ActiveSync connectivity tests. The tests are run sequentially, and the results are now viewable in a web format that is similar to http://www.testexchangeconnectivity.com. Compatibility with Microsoft Office 2013 and Microsoft Office Click-To-Run – MOSDAL is now aware of and will collect data for Outlook 2013 and Lync 2013. In addition, if you installed Office 2013 through Click-To-Run, MOSDAL will collect additional data to help troubleshoot Click-to-Run installation and activation issues. Compatibility with Microsoft Windows 8, Windows Server 2012 and .NET 4.5 – MOSDAL will now run without issues on Microsoft Windows 8, Windows Server 2012 and on systems with .NET 4.5 installed. WebDAV ETL component logging for SharePoint Online – Logs are collected by MOSDAL to help troubleshoot issues WebDAV connections to SharePoint Online. Directory Synchronization, Domains/DNS and Exchange Hybrid Configuration reports in XML – Many of the reports generated by MOSDAL are now in XML format to make them easier to read and easier to create automated diagnostics to help identify issues quicker. Windows Network Trace logging – Network tracing utilizes the Event Tracing for Windows (ETW) framework available in Windows. Network components (such as Winsock, TCP/IP, NDIS, packet-capture, and so on) register as ETW trace providers and emit events related to network activity. Any recordable activity of significance can be an event logged to ETW. Tracing for these network components and packet captures can be enabled using the netsh trace context which acts as an ETW controller.
