Does this website help you with finding out how to do it.

How to: Disable auto hyperlink in Word 2007..

In the Oct 1 post you stated "...and this only happens in Outlook 2007 e-mail." So this popup happens with one or more emails in Outlook, correct? As stated in other replies, Outlook shows this as a security concern.

Now, what is this? I followed some leads from your screen shot, specificly customer.io which is used to track real-time customer behavior, send targeted marketing, etc. It looks like your hyperlink is embedded in an email to send your data somewhere and Outlook is blocking it (probably a good thing).

Ways to get rid of the pop up include using a different mail client that allows the silent embedded behavior or blocks it without a warning, or you could copy the email as plain text and create a text document, then send it to yourself and delete the original.
