Random Scammy PDFs Appearing in "Recent"

It's been some time since you created this post, but perhaps this information could still help you.

If I may recommend from the outsett, never click "Open" or "Download" on these files. They are very likely scams or could contain malware.

Try these steps in order to remove them:

Method 1: Remove from the "Shared" List (Most Direct)

1. In OneDrive on the web, click "Shared" in the left navigation pane.
2. Look for the offending files in the "Shared with you" list.
3. Select the file(s), and on the toolbar or by right-clicking, look for an option like "Remove from shared list" or "Remove from this list." This should hide them from your view, including the "Recent" list.

Method 2: Try Directly in the "Recent" View

1. Stay on the "Recent" page.
2. Hover over one of the offending files, or click the "..." (More actions) icon that appears next to the name.
3. Carefully check the context menu for an option like "Remove from list" or "Hide."

Method 3: Adjust Notification Settings (Preventative)
To potentially stop these from appearing in the future, you can try to change your sharing notification settings:

1. Click the Settings gear icon in the top right of OneDrive > "Options."
2. Go to "Notifications."
3. Under a section like "Someone shares a document with me," try turning off notifications. Sometimes this can prevent the items from being pushed to your "Recent" list.
