CloudBacko version 184.108.40.206 is just released, with:
1). Support of Office 365 Modern Authentication
2). Quick Multiple Users Selection in Office 365 Backup Set
3). Enhanced Periodic Data Integrity Check, and
4). VMware Version Check for Changed Block Tracking Issues.
As Microsoft is going to enforce the use of Modern Authentication Method and begin disabling Basic Authentication in existing tenants with no recorded usage as early as October 2020, if you are currently running Office 365 backup sets, you MUST upgrade your CloudBacko Pro / Lite to this version before Basic Authentication is disabled.
