How can I use the new attachments on tasks and events feature?

Note: This article applies to Salesforce Classic and not Lightning Experience.
|Resolution||If users are allowed to add attachments to tasks and events, they must edit the task or event in order to display the 'Attach File' button in the Attachments related list. The 'Attach File' button does not display in the Attachments related list when only viewing a task or event. This is in contrast to other standard objects in Salesforce where the parent record does not have to be edited in order to add an attachment to the record.|
