SharePoint user records are different than Office365 user records.
If you are trying to set the default of a combobox (which actually does nothing on a combobox - you need DefaultSelectedItems) based on a Person column, then you need to convert to the appropriate record.
I am assuming that your Combobox has an Items property based on your person column - something like : Choices([@yourDataSource].personColumnName)
If so, then you need to set the DefaultSelectedItems property to the following:
Coalesce(
Parent.Default,
With({_user365: Office365Users.ManagerV2(User().Email)},
{
Claims:"i:0#.f|membership|" & Lower(_user365.mail),
Department:"",
DisplayName: _user365.displayName,
Email: _suer365.mail,
JobTitle:".",
Picture:"."
}
)
)
This will set the default properly based on the Items property.
It will also set the selected person to be the default of the record (the underlying value) for when you are editing a record. If there is NO underlying value (new record), then it will set it to the manager from 365.
I hope this is helpful for you.
