I've got a client who emails Excel files which are created from templates and contain cells which are protected and also a macro with password protection. The password for both cells and macro are the same. The original templates were created with Excel 2000. Now when the files are dragged and dropped from Outlook Express to a network shared folder some of them are asking for a password to open them using Excel 2003. They can be opened using the password which protects both the cells and the macro. This problem has only surfaced since I upgraded to XP and Office 2003.
