we open a workbook (having protection and a password for it) with IG excel engine. After writing data to some cells we then save the workbook with a different name.
This copy is still protected, but doesn't have a password for the protection anymore. The user can simply press the "unprotect Sheet" button and is not not asked for a password.
This is a huge problem for us.
Getting this error attaching the file here. Tried different browsers.
I have created a private case CAS-200054-B1C8B0 with you in order to share the sample and having easy communication.
