I try to open an Excel document to work on but Libre Office only opens it in ‘Read only’ mode
- the file is opened directly from an email attachment
Save the attachment first then open it.
- The file is not properly closed after saving, so it is marked as “in use” in the file system.
This typically happens when you save from Excel to a USB stick, and pull the stick while the file is still open. It can also sometimes happen if you make a copy of a file while the source file is open.
