Here is a snippet from the CPUU 5.8.3 Release Notes:

This release introduced the following new feature:

Support for migration to Microsoft Office 365 tenants with modern authentication enabled and optionally Multi-Factor Authentication (MFA) enabled.

Previously this functionality was partially supported by means of disabling modern authentication in Outlook settings for the time of profile processing, but this method cannot be used now due to recent changes made by Microsoft in updates for Microsoft Outlook for Office 365 / Outlook 2016 and in Outlook 2019. Now authentication process can be delegated to Outlook that allows Client Profile Updating Utility to access target mailbox with modern authentication and MFA. To enable this behavior the -LogonThroughOutlook command line parameter is introduced in this release. If this parameter is specified in Client Profile Updating Utility command line, Client Profile Updating Utility is allowed to initiate start of Outlook for prompting target user credentials and performing authentication process. Some restrictions may apply. Refer to the Workaround 1 specified in Known Issue CPUU-1266 for details.

IMPORTANT: After this update is installed, CPUU.ini should be recreated for existing projects due to deprecation of the following configuration parameters:

• BypassModernAuthentication
• CleanupCredentialManager

Or the parameters mentioned above should be removed from existing ini file.
