Copilot Template Notes — Issue 001

Published: July 22, 2026

Microsoft updated its Copilot template guidance on June 15, 2026

On June 15, Microsoft republished its guidance for optimizing PowerPoint templates for Copilot. Two changes are worth knowing if you maintain a template library:

Sample slides are now the primary signal. Copilot reads a template's filled example slides first, and falls back to the Slide Master and layout structure only when a template doesn't have enough sample slides. Previously, layout structure carried more of the weight. If your template library is light on filled examples, this is the thing to fix first.

Recommended layout categories expanded from six to twelve. The original guidance suggested a handful of core layout types. The current guidance lists twelve, covering a wider range of content patterns, comparisons, data visualization, timelines, and process flows among them.

What this means for templates already in circulation

Templates that were fully compliant under the previous guidance may no longer reflect current best practice. This isn't a flaw introduced by the template, it's the guidance itself moving. Microsoft's documentation doesn't retroactively flag this, so there's no built-in way to know a template has drifted out of date unless you're checking it against the current published guidance directly.

We've updated our checks to conform to the guidance as published in July 2026. Templates certified before June 15 reference the prior version of Microsoft's guidance and should be re-checked.

What changed on our end

We removed checks that no longer reflect current guidance, and adjusted how templates are scored so that sample-slide quality and design signals carry more weight, in line with Microsoft's shift.
