Sending, receiving, and organizing email in Outlook.com
Hi @david nolan
Since the Trust Center option is not displayed, could you please confirm which Outlook version you are using?
- Classic Outlook for Windows: You see a File tab in the upper-left corner.
- New Outlook for Windows: There is no File tab, and you normally see a Settings gear icon.
- Outlook on the web: You access Outlook through a web browser.
Please also let us know what happens when you select the PDF attachment, whether you receive an error message, and whether Download or Save As allows you to choose the Desktop or Downloads folder.
This information will help us provide the correct troubleshooting steps for your Outlook version.
