A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data
Dear @UrielVilla-4507,
I hope you’re having a good day.
Thank you for explaining the situation in detail.
In Microsoft 365, it’s important to know that being able to open a file and being able to edit a file are two different permission levels. Even if you are an admin, edit access to documents is controlled at the file level, not by admin role.
Here are the main things I recommend checking, in order:
First, please confirm which account you are signed into in Excel or PowerPoint. If you have more than one Microsoft account (for example, a work account and a personal Microsoft account), the apps may be opened with the wrong one.
You can check this by selecting your profile picture in the app and making sure it matches the account that originally created the files.
Next, check where the files are stored. Open the files from OneDrive or SharePoint in a browser. Locate the spreadsheet and PowerPoint, then select Share or Manage access and check who is listed as the Owner
check who is listed as the Owner
and whether your account has Edit or only View permission
If your account only shows View, you won’t be able to enable editing yourself.
If the files are stored in your partner’s OneDrive or in a SharePoint site where you only have read access, your partner (or another admin with access) will need to explicitly assign you Edit or Owner permissions on those files.
If your partner confirms that you are the only admin and no one else has owner access, you can also try opening the files directly from OneDrive or SharePoint Admin Center, take ownership of the files, and then grant yourself edit rights. Once ownership or edit permission is restored, the files should no longer open as view‑only.
You can find more details here: Manage site admins - SharePoint in Microsoft 365 | Microsoft Learn
Lastly, if you are opening the files from an old email, chat message, or saved link, try opening them directly from OneDrive or SharePoint instead. Sometimes older links are shared with view‑only access, even if your permissions have changed since then.
I hope this information helps point you in the right direction. Please feel free to reply below if you have any update or further concern.
