The first place I would check is the file share permissions. There is a VMware Fling for persona management share validation:
Horizon View Persona Management Share Validation Tool – VMware Labs
A different thread on here had similar error messages, and the fix was to set Full Control on the persona share. You can read about it here:
View Persona not syncing some users
If you validate the share permissions are right, and you still have problems, please post a bit more info on your config.
