How do I have a PowerPoint auto start and auto full screen within SharePoint 365

Hi @CGimro ,

You can change the URL to show the file in presentation mode by changing the page.

There are two workarounds for this：

1.Change the Doc.aspx to wopiframe.aspx

Let me give you an example:https://domain.sharepoint.com/:p:/r/personal/account_onmicrosoft>com/_layouts/15/Doc.aspx?sourcedoc=%7BFBF4CB1F-003F-40E3-81DF-06DDFD364894%7D&file=Team%20Meeting%2020230221.ppsx&action=edit&mobileredirect=true

Change URL (fullscreen demo mode):https://domain.sharepoint.com/:p:/r/personal/account_onmicrosoft>com/_layouts/15/wopiframe.aspx?sourcedoc=%7BFBF4CB1F-003F-40E3-81DF-06DDFD364894%7D&file=Team%20Meeting%2020230221.ppsx&action=edit&mobileredirect=true

2.Change the action=edit&mobileredirect=true to &action=embedview.

Example:https://domain.sharepoint.com/:p:/r/personal/account_onmicrosoft>com/_layouts/15/Doc.aspx?sourcedoc=%7BFBF4CB1F-003F-40E3-81DF-06DDFD364894%7D&file=Team%20Meeting%2020230221.ppsx&action=embedview

Sorry, this is not currently possible. There are several Feedback suggestions requesting the addition of this capability, here is the one with the most votes: https://feedbackportal.microsoft.com/feedback/idea/b598c187-ebf1-ee11-a73d-000d3a04e3e2

Please add you vote to make it more likely that MS will finally fix this.

No luck in 2025. Might this workaround have been changed or updated?

Here is my link from the url browser:

https://wearelitedu-my.sharepoint.com/:p:/g/personal/support_wearelitedu_onmicrosoft_com/EdrQWtsBc9BAurQd4xeosk0BCiBnRhd2L-RaRSkFPXGgcw

As you can see, "doc.aspx" doesn't show in this link... Somehow I've found another link and have replaced the "doc.aspx" with "wireframe.aspx" but it's still not a solution.

I've also tested the solution by utilizing a different user on my computer not associated with my onedrive account and still no fix. I'd be grateful if any suggestions towards a solution were provided.

Thank you.
