Hello,
Yes, it is possible. For example, you can use a Business Rule and a Scheduled Task. The Business Rule will trigger After disabling a user account and set a custom date attribute (e.g. CustomAttributeDate1) to the current date plus 30 days. The Scheduled Task will check the dates in CustomAttributeDate1 of users and if the date is today, it will get users from the Full Access list and send notifications to them. If this approach meets your needs, we will provide you with detailed instructions for creating the rule and the task.
If there is anything you need to add to the solution, please, provide us with all the possible details.
