Every experience in Office is designed using the principle “the user is in control.” It\u2019s critical that customers are the ones who make choices about their user experience, ensuring it fits their specific needs and workflows.<\/p>\n
Customers have asked for greater user control over add-in launch behavior in Office. Specifically, integrations into our applications via our add-in framework have been automatically appearing when documents are opened without user notice and without the ability to disable that behavior, causing confusion and frustration.<\/p>\n
After careful consideration, we are making three adjustments\u00a0to the behavior of add-ins distributed through the Microsoft Marketplace to address this customer feedback:<\/p>\n
\u2013\u00a0 Excel<\/strong>: When the workbook uses custom functions provided by an add-in and cannot calculate correctly without it.<\/p>\n \u2013\u00a0 Excel and PowerPoint<\/strong>: When the file contains content add-ins that must be loaded for a worksheet or slide to render correctly.<\/p>\n With these changes, developers should consider updating their product documentation and add-in experiences to guide their users on best practices for inviting others to benefit from their add-in. For example, users could add a note about the add-in when sharing a document with others or embed a link to the Microsoft Marketplace listing in an appropriate place in the document.<\/p>\n These changes do not affect the runtime behavior of add-ins\u2014they will only impact the conditions under which the add-in can automatically launch UI without explicit user choice.<\/p>\n Show or hide the task pane of your Office Add-in<\/a><\/p>\nSee also<\/h3>\n
