Understanding links in email messages
There are several reasons you might not see links enabled in your email messages (when sending or receiving email messages).
To troubleshoot links not working in an email message, use the following steps.
Check to see if the email message you're composing or viewing is in plain text.
Check to see if an InfoBar at the top of the message informs you that links are disabled. If so, click the button in the InfoBar to enable external content.
In Outlook 2010, check your Junk Email options.
In the Delete group, select Junk > Junk Email options.
On the Options tab, clear the Disable links and other functionality in phishing messages (recommended) checkbox.
If some (not all) of your links can see and use your links and some cannot, it is mostly point 1.
Change the message format to HTML, Rich Text Format, or plain text
Error occurs when you send or receive an email message in Outlook or Outlook Express
