apparently someone has deleted something. one time,i could go on to craigslist and inquire about something,and send a email. through craigslist now i cant send a email.
Need a little more info...
Do you normally use Outlook for your email? If so, did you install a new version of Microsoft Office? What happened before when you click on the email link on craigslist, did it just open an email?
Is the craigslist ad just missing the email link? Usually at the top of the ad there is a Reply To: and then something like '[email protected]' but when the person creates the ad they have the option not to include this email address and there should be contact info in the ad.
