Hi @tobz
- Verify that the file isn’t actual open (check task manager for suspicious EXCEL.EXE processes)
- Verify that there are no other SSIS packages (or other background processes) that might be opening this file at the same time
If you are using agent job to run the package, you may try with proxy account with full permission.
Run an SSIS Package Under a Different Account
