In Word for Windows, read the banner above the document. If it says Protected View, keep it there while reading. Select Enable Editing only when you need to make changes and have verified the source and contents. If there is no Protected View banner, check the document’s editing mode and your access.
01Read the reason Word gives
Section linkWord can open downloaded files and attachments in Protected View. If you expected the document and trust what is in it, use Enable Editing on the yellow banner when you need to work on it. For an unexpected attachment or a warning that Word found a problem with the file, ask the sender for a verified copy through a channel you already trust.
02If the editing button is missing
Section linkOn a work or school PC, an administrator can block leaving Protected View. Ask your administrator about the specific warning or request an approved copy from the sender. Leave the Office security settings in place.
03If Word only says read-only
Section linkWhen a trusted document you control is set to open read-only, check File → Info → Protect Document → Always Open Read-Only. Clear the option if you want that document to open for editing. If the upper-right menu says Viewing or Reviewing, try switching it to Editing. If Editing is unavailable on a shared file, ask the owner for permission.
04Confirm you can save to the intended file
Section linkCheck that Word is in Editing mode before making substantial changes. If you can edit the text but cannot save back to the shared original, ask the owner to confirm your access to that file. Save a separate copy only if that fits how you plan to share the changes.
