i have created an subclient for the onedrive backup for each Name one Subclient.
So there are ~100 user per Letter this is working without no problem.
The Default subclient has the option Automatically add new mailboxes that do not qualify for membership in any of the sublcients.
In my case none because all user are in subclient. When the default subclient is starting the backup the job completed with errors: No user found to backup. Please check subclient contents
is there any option to overwrite the error and let the job completed like empty subclients under vsa backup ?
