I have created few document libraries and each one have few MS Excel files. I have a Excel file which has cell input from other excel files from the different libraries. All the document libraries require login and password to see the documents as well as they must be checked-out for any modification. I have access to all the document libraries and also authoriesed to modify and save the content. But whenever i am updating any ecel file, the linked excel cell in other are files are not getting updated and giving error for link. Please help how to resolve this. Thanks.
