NM: Autodiscover [Error] Invalid Parameters for ... (4332037)

Issue

We are attempting to migrate our users, and we receive the following error

Calling autodiscover application: "C:\Program Files (x86)\Binary Tree\CMT for Exchange\Worker\OutlookAgent32.exe" -address name@domain.com -user "yourinfo@tenant.onmicrosoft.com" -password "" -type mailbox -profile "CMT Temp Migration Profile" -l "C:\Users\adu_bt_svc\AppData\Local\Binary Tree\Notes Migrator\BTautodiscover.log"
Begin AutoDiscover and Profile Creation Log
[Error] Invalid Parameters for Server/Archive
End of AutoDiscover and Profile Creation Log
AutoDiscover Response for Mailbox not found C:\Users\bt_svc\AppData\Local\Binary Tree\Notes Migrator\name@domain.com-AutoDiscover-Mailbox.xml
Error: AutoDiscover Mailbox LegacyDN not found.
Error: Failed to initialize : User Name

We don't understand why the autodiscover credentials are blank. The Settings - Additional tab are configured correctly, and the Worker Connectivity Tester passes.

What is causing these migrations to fail?

Save the migration document
