Blackboard - Known Issue: Web Folders and Blackboard Drive Not Working
Faculty are advised instead to use the file and folder upload option to send one or more files to Blackboard courses or the Content Collection. This article describes how to use the multi-file upload feature in the Content Collection. You can use this feature anywhere in Blackboard where you can attach documents, including inside of course folders.
Faculty can no longer log into Blackboard's Web Folders and Blackboard Drive. Blackboard is aware of this issue and has not yet offered a resolution.
