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 Office 365. The logs and diagnostic information 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.
This article contains the following information about the MOSDAL Support Toolkit:
Note Services such as the "Domain Verification and DNS Setup" service and the "Single Sign-on with Active Directory Federation Services" service require you to have the Windows Azure Active Directory Module for Windows PowerShell
(http://onlinehelp.microsoft.com/Office365-enterprises/ff652560.aspx#BKMK_DownloadTheMOSIdentityFederationTool)already installed on your computer. MOSDAL uses the Windows Azure Active Directory Module for Windows PowerShell to connect to Office 365 and to collect data by using the credentials that you supply in MOSDAL.
Why use the MOSDAL Support Toolkit, and what can it help me do?The MOSDAL Support Toolkit should be used as a preemptive tool before you contact Microsoft Online Services Support. If it is possible, use the MOSDAL Support Toolkit at the time that you experience a problem or an issue with Office 365.
What kinds of services can the MOSDAL Support Toolkit help me with?
New in the MOSDAL Support Toolkit 4.6With the release of the MOSDAL Support Toolkit 4.6, we introduce several exciting new features and improve the user experience yet again so that both users (information workers) and admins can collect the correct data for the correct problem. In this release, we tried to make the MOSDAL tool and its output more user-friendly. We made improvements to the user interface (UI) to help guide users through the data-collection process, and we improved the readability of many reports that MOSDAL generates. MOSDAL 4.6 includes the following improvements:
How to collect the correct data by using the MOSDAL Support ToolkitThe MOSDAL Support Toolkit must be run on the computer on which the problems occur and in the context of the user who is experiencing issues with the service. If you use MOSDAL to collect data for any of the following services, you should run MOSDAL on the computer on which those applications are hosted in the on-premises environment:
When MOSDAL starts, click to select the check box next to the services with which you are experiencing an issue. Depending on the services that you select, MOSDAL collects information about the applications that are used by that service and stores the data in centralized folder. This makes it easier to analyze the data or to send the data to Microsoft Support for additional assistance. Local admins on the computer have additional options for Exchange migration, directory synchronization, and SSO. However, these services should be diagnosed only on the computers that host those features, such as the AD FS 2.0 server or the server on which the Windows Azure Active Directory Sync Tool is installed.
Entering credentials in MOSDALDepending on the services that you select, MOSDAL may require you to enter your Office 365 credentials to perform diagnostics and connect to certain Office 365 services. The credentials that you enter will be used for various tests. However, MOSDAL will not store these credentials anywhere. If you decide not to enter credentials, the following modules will not be completed.
When the report generation is finished, click Exit and Show Files to view the report. When a new report is generated, a folder is created in the MOSDAL subfolder in the user's My Documents folder. The folder that is created is named by using the following format:
REPORTS-Date_TimeFor example, REPORTS_6_17_2011_10_25_21_AM indicates that files were collected on June 17, 2011, at 10:25:21 AM. The compiled report is compressed into a file that is named MOSDALREPORT.zip.
What kind of data is collected by the MOSDAL Support Toolkit?The data that the MOSDAL Support Toolkit generates and collects contains log files that are specific to the applications that are related to the services that are selected. The data also contains information about the computer on which MOSDAL is installed. The results are organized into a folder hierarchy, based on the application or the component. The following tables list the applications for which MOSDAL collects data, based on the services that are selected when MOSDAL starts.
Note MOSDAL collects information about the computer configuration in the context of the user who is currently logged on to the system and who runs the tool. MOSDAL can be run by an admin or by a non-admin user.
The following table shows the mapping of Office 365 services to the modules in MOSDAL.

Network configuration and diagnosticsIn addition to collecting information about the computer or about installed applications, the MOSDAL Support Toolkit also obtains information about the network configuration of the computer and about the network to which the computer is connected. MOSDAL also uses standard command-line tools to perform network diagnostics against specific URLs in both public domains (such as Bing.com) and private domains (Office 365 data centers). Configuration information that is captured includes the computer's IP address, subnet mask, default gateway, Domain Name System (DNS) servers, Address Resolution Protocol (ARP) tables, Host file, static routes, and other similar information.
Prominent data that is collected about the system will help troubleshoot problems that include Windows firewall settings, proxy settings, installed applications, installed hotfixes, event logs, and Msinfo32 output. For each application that is listed in the tables earlier in this article, MOSDAL verifies that the application is installed and then collects the version number of certain program files, relevant registry keys, configuration files, logs, and other such pertinent data.
Making sense of MOSDAL outputThe following table outlines where the results of each module are stored. Cross-reference the tables in the previous section to see the service that you should diagnose to obtain results for the following modules.
