If your **AOL Mail is not opening PDF attachments**, it’s likely due to browser settings, outdated PDF readers, or AOL’s built-in file protection. Manually resolving this involves several steps. First, ensure that your web browser is updated and that pop-ups or downloads aren't being blocked. Next, verify that a compatible PDF reader like Adobe Acrobat is installed and set as your default viewer. Then, try downloading the PDF instead of previewing it—right-click the attachment and select "Save As" to store it on your computer before opening. However, this process can be time-consuming and frustrating, especially if you deal with multiple emails or large attachments frequently. Compatibility issues between browsers and AOL’s interface can further complicate access. 

A more efficient solution is using the Cigati AOL Backup Tool, which allows users to back up their AOL emails along with attachments like PDFs to various formats such as PST, PDF, or even directly to other email clients.
