Office 365 for professionals and small businesses

 Office 365 for enterprises


We are happy to announce the release of Microsoft Online Services Diagnostic and Logging (MOSDAL) Support Toolkit version 4.0. This release brings an enhanced, more intuitive user experience, improved Training and inclusion of MOSDAL usage in several Office 365 and BPOS-S Troubleshooting Knowledge Base articles, just to name a few prominent features.


The Microsoft Online Services Diagnostics and Logging (MOSDAL) Support Toolkit performs network diagnostics and collects system configuration, network configuration, and logging information for applications that are used to connect to Microsoft Business Productivity Online Standard Suite (BPOS-S) or to Microsoft Office 365. The logs that the tool generates provide data that helps technical support professionals troubleshoot configuration, network, installation, and other service-related issues. The MOSDAL Support Toolkit collects log files, registry keys, and configuration settings that would otherwise require time-consuming and labor-intensive collection by using separate tools.


New Features in MOSDAL 4.0

  • Improved user experience and user interface
  • Training completely revamped to include troubleshooting scenarios and diagnostics
  • Increased number of Microsoft Knowledge Base articles that show how to use MOSDAL
  • Added configuration file for system flexibility and modularity
  • Added user account control management and Active Directory Federation Services (AD FS) PowerShell commandlets
  • Additional Directory Synchronization diagnostics information captured
  • Changed localization management to a more manageable solution
