Where Can I Locate the Transporter Tool Files?

After the Transporter Tool (or Migration Tool) is downloaded and used, MOSDAL stores the following files and folders in the Transporter_Tool folder of the MOSDAL Report.

NOTE: All files included in the Transporter_Tool folder are not described below:

When first launching the Migration Tools Console (MMC), the MMC runs an LDAP system query against the on-premise Active Directory (AD), looking for mailbox-enabled users. After entering the MSOL admin credentials, the Transporter Tool then attempts to match the users found in the on-premise AD with users in the cloud, based upon SMTP address.

During the migration process, the Transporter Tool uses the mail server information returned by the initial AD query, attempting to connect to the mailbox and extract the mailbox data.

When troubleshooting connectivity to the on-premise mailbox, it is important to understand that the Transporter Tool connects to the mailbox via WebDAV. There are two virtual directories within IIS: /Exchange and /Exadmin. The Transporter Tool attempts to negotiate NTLM with the both virtual directories. The first virtual directory to negotiate NTLM is used to access the mailbox. The /Exadmin virtual directory requires Exchange Organization Admin rights. The /Exchange virtual directory requires delegation of full mailbox access. The Transporter Tool attempts to build a URL that contains the DNS name of the server, the virtual directory name, and the alias or e-mail address, until the source mailbox is located. If the mailbox URL discovery fails, an error message is displayed with the URL (Graphic 26). If unable to locate the user’s source mailbox, the error IIS return codes can be used to troubleshoot.    

NOTE: When troubleshooting IIS, logging must be enabled. This is applicable for IIS 6 or IIS 7. MOSDAL does not collect IIS logs. IIS logs are required when troubleshooting a specific IIS return code, as the sub-status code helps identify the root cause of the problem.
