I have a document library on SP 2010 in which all users, including myself as the admin/owner, are unable to update properties of certain documents.
Documents were moved to this folder from another folder on the same Sharepoint site, using the Site Content Structure tool. The columns and content types were matching. The documents were of the .doc (Office 2003) type.
The .doc files were converted to .docx. While we were able to update the document properties of the .doc files, we cannot do it with .docx. The property edit window pops up, I can edit the properties, change the content type etc., apply the changes and... Nothing happens. No error messages, but no updates either. The old properties won't budge.
I found .doc to work fine, but we need to convert to 2007.
Interestingly, new .docx files in this library work OK (we can edit the properties). Also, if a .docx with uneditable properties is moved to another library, they will remain uneditable.
EDIT: this happens to .xlsx and .pptx files converted from the existing 2003 files as well. Non-Office files are not affected.
Does anyone have any hints? What may have caused this? I'm completely stuck.
