A Microsoft file hosting and synchronization service.
Hello Helena ku,
If promotional pages are interrupting you while deleting Word documents, could you try going directly to OneDrive?
Sign in, open My files, select the documents you want to remove, and choose Delete.
If OneDrive is synced to your PC, you can also delete them through File Explorer, although this removes the files from OneDrive online as well. Delete files or folders in OneDrive.
Let me know if you're still being redirected to promotional pages when accessing OneDrive directly.
