SyncIQ target directory will be read only as per design However same permission will get transferred from source directory to target directory once you break  association from source to target you will see same permission on source & target folders.

When you create an SMB share, you can override the default permissions, performance,

and access settings. You can configure SMB home directory provisioning by including

expansion variables in the share path to automatically create and redirect users to their

own home directories.

To apply a default ACL to the shared directory, click Apply Windows default ACLs

If the Auto-Create Directories setting is enabled, OneFS creates an ACL with

the equivalent of UNIX 700 mode bit permissions for any directory that is created

automatically.

To maintain the existing permissions on the shared directory, click Do not change

existing permissions.

You can get same definition in Admin guide..

Thanks, sounds like the answer is Yes then (Do not change existing permissions), based on:

To maintain the existing permissions on the shared directory, click Do not change

existing permissions.

And this setting has no ongoing affects on the share? As in it only changes the permissions when it is first created and not continually.

Yes
