A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Microsoft 365 Basic does not include a license for the Excel desktop app. It provides 100 GB of OneDrive storage, but not desktop editing rights for Word or Excel. That is why the file opens read-only and prompts for a higher plan when editing is attempted.
What this means for the current issue:
- The 100 GB storage showing correctly indicates the Basic plan is active.
- The edit prompt is caused by the plan not including desktop Office app licensing.
- The file being in OneDrive does not change that limitation.
Practical options:
- Open the workbook in the web version instead of the desktop app.
- If desktop editing is required, move to a plan that includes the Office desktop apps.
If the file still opens read-only in OneDrive web, also check whether OneDrive storage is over quota, because over-quota files become read-only until storage is reduced.
