I am wondering if it is possible to be notified if a Sharepoint user and/or group has not been used in a specified amount of time. For example, if user - "Bob" does not log into our sharepoint site in 30 days a notification will be sent out. Also, if there is a sharepoint permission group - "SubSiteSuper" whose users do not access the site/list/item of which "SubSiteSuper" has permissions on in 30 days a notification goes out.
My main goal here is to be able to manage unused permissions groups and its users so that they can be manually or automatically deleted. If anyone has heard of something like this via a custom workflow or third party application please help!
