Renaming groups in your directory
Once you have synchronized your groups with the cloud service, we recommend that you do not rename them in the directory. If you do rename a synchronized group, the new group name is automatically sent to the cloud service on the next synchronization.
If you have set up any group-based black and white list settings for Forcepoint Email Security Cloud, however, you must manually reapply those settings to the new group name in the cloud portal.
