Comparing @mention vs Watch List functionalitiesIssue Emails go out to users with only ITIL licenses if you @mention them in additional comments and worknotes. Non ITIL users do not get the email notification.ResolutionIn the current platform there is no out-of-the-box supported way to change the behavior of the @mention feature. It is not possible to:1 - Not return users who can not see the record2 - Limit the @mention feature to certain roles (e.g. only users with the itil role)3 - Disable the @mention featureIt is possible to implement a customization to disable the @mention feature, or restrict it to certain roles, based on a workaround described in this Community article:https://community.servicenow.com/community?id=community_question&sys_id=1bf50761db1cdbc01dcaf3231f961981NOTE: ServiceNow does not support such a custom workaround.
