PDF files load very slowly – Microsoft Outlook Review

When a pdf file is opened within Outlook, the loading time is very slow. Compared to Apple Mail, the loading time is more than 10 times slower. Is this a common observation shared by others. Other than that the formatting of mails in Outlook is better than Apple Mail. Its the slow downloads of attachments that is stopping me from using Outlook as the primary mail platform.
