To enforce the company policy of not sending file attachments externally, the most effective solution is to create an attachment compliance rule. This rule can be configured to automatically remove attachments from emails sent to external recipients. Additionally, it can notify the sender that their email violated the company policy, ensuring they are aware of the restriction.

* Preventing Widespread Deletions:
* Configuring deletion limits helps prevent accidental or mass deletions if there's a substantial
* change in the LDAP directory.
* Steps to Configure Deletion Limits:
* Open the Google Cloud Directory Sync (GCDS) Configuration Manager.
* Go to "General Settings" and locate the "Deletion Limits" section.
* Set the maximum number of deletions allowed per sync. This will pause the synchronization if the number of deletions exceeds the specified limit, allowing you to review and approve the changes manually.
* Save the configuration and test the synchronization process to ensure the limits are properly applied.
