Hi RR-10041022-0

Unfortunately this is not possible natively in Copilot for PowerPoint, it simply cannot respect custom corporate templates reliably.

A solution I have done multiple times: use an Azure Function in Python with the python-pptx library. The idea is to reverse engineer your corporate template (fonts, colors, layouts, placeholders), recreate it in Python, and inject your dynamic data programmatically.

You then orchestrate everything with Power Automate, it triggers the Azure Function, passes the data, and retrieves the generated .pptx ready to use.

I'll be happy to help if you have more specific questions on this subject!

Hi @RR-10041022-0

By design Microsoft Copilot chat / Embeded Experience and Copilot App relies on data available either in Users OneDrive or Sharepoint.

The issue faced by you can be addressed by Sharepoint Admin intervention or you can do it yourself provided you are granted the privileges of Site Owner.

This is going to be a Four step process
Step 1: Ask your SharePoint Admin to create a Shared Document Library or if you are the Site Owner you can do it yourself
a) Go to Sharepoint Site --> Settings -->SiteContents --> New --> Document Library

b) Name it something like OrgTemplates
c) Open Library --> Upload PowerPoint Templates (.potx recomended)

Step 2: Assign Required Permissions
a) Add yourself as owner of the site and target library

b) Grant "Everyone except external users" Read access:

(Below steps to be performed from an elevated PowerShell as admin)

Step 3: Connect SharePoint Online

a) Install-Module -Name Microsoft.Online.SharePoint.PowerShell
b) Import-Module Microsoft.Online.SharePoint.PowerShell

c) Set-SPOTenantCdnEnabled -CdnType Public
d) Connect-SPOService -Url https://<tenant>-admin.sharepoint.com

Step 4: Register the Library as Organization Asset
Add-SPOOrgAssetsLibrary -LibraryUrl https://<tenant>.sharepoint.com/sites/<site-name>/OrgTemplates -OrgAssetType OfficeTemplateLibrary

Wait for Sync
a) Templates appear in 24 Hours max.

b) No Client setup required
c) It works for

Powerpoint Desktop

Powerpoint Web

Copilot in PowerPoint

if you face any challenge in above steps do let me know ,shall create a step-by-step Video and publish it on youtube.

What you're experiencing is not a bug, it's an architectural boundary. Microsoft Copilot in the PowerPoint app context operates as a content assistant, not a file manipulation engine. It can generate structured, layout-ready content, but the actual insertion into your open file requires a human action inside the PowerPoint interface itself.
Here's what actually works in your scenario:
If you want Copilot to work with your company template specifically:Use Copilot in PowerPoint via Microsoft 365 (not Copilot Studio) and open your template file first before prompting. Copilot will then generate slides that respect your existing layout, theme, and placeholders.

If you're in Copilot Studio building a custom solution: You would need to integrate with the Microsoft Graph API combined with the Office Add-ins framework to programmatically insert and modify slide content. Copilot Studio alone cannot write directly into a PowerPoint file — it needs a connector or custom action to bridge that gap.

Practical workaround for now:Let Copilot generate the content and structure, then use PowerPoint's Designer or paste into your template manually. It's an extra step, but it keeps your brand standards intact.

The short answer: Copilot prepares, you insert. Until Microsoft expands direct file-write capabilities, that boundary holds.

Hope this helps unblock you. Happy to go deeper on the Graph API route if that's the direction you're headed.

Warm Regards,

Hi @Seun Ogunsanya,

Thank you for your quick response, I would like to deep dive into MS graph solution, could you please help me further, i believe that this one manual of pasting content will spoil the experience of using copilot up to full extent.
