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

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

Here is my link from the url browser:

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.
