Problem description: If you create an encrypted Word docx file in either Libre Office 4.2.2.1 or Word 2010, then edit it in Word, Libre Office will thereafter fail to read the document properly. Word will read the document properly. Steps to reproduce: 1a. Create the document in LO, save as .docx, save with password -or 1b. Create the document in Word, save as .docx, save with password 2. Open the document in LO - works 3. Open the document in Word - you are asked for password - works 4. Edit the document in Word - you are asked for password - works 5. LO can no longer display the file contents - no password prompt - garbage 6. You can continue to work with the document in Word, LO can no longer read it however. Example 1 (actual text in file) ----- Encrypted document 1 Creation in LibreOffice. Edited in Word 2010. ----- File can no longer be viewed in LO, but it can in Office. Example 2 (actual text in file) ---- Test document 2 Creation in Word Edit in LO Edit in Word ---- File can no longer be viewed in LO, but it can in Office. Current behavior: Thus, LO can read a .docx created in either LO or Word, but once it has been edited by Word after being edited in LO, LO can no longer read it. Expected behavior: Round trip between LO and Word should work. This bug makes LO<->Word interoperability useless for password-protected documents. Operating System: Windows 7 Version: 4.2.2.1 release
I cant reproduce this on the latest release of 4.2.4. I had attempted to save the password protected file from within LibreOffice, but word 2010 couldnt open it (bug 79476). Please send us a sample of the file you edited in Word 2010 but cant reopen in LibreOffice, so we can test it.

Comment on attachment 100852 [details] demo files for bug 76873 I can reproduce this in 4.2.2.1, but not in 4.2.4.2. It looks like the problem has been fixed. Writer 4.2.2.1 fails to open the files in both cases after the document has been edited by LO and then subsequently by Word. Writer 4.2.4.2 works properly. Thus it looks like the file opening problem has definitely been fixed. This time I saved the files in case anyone wants to see them. I'm sure the Office XML format is pretty tricky. There is an interesting change in metadata when an Office-created file is edited in LO, that may be of interest.
