When attempting to log in using StackExchange, I am told I am not accepting third party cookies. I am using IE 9 and I have set security and privacy settings to absolute minimum, as well as added exceptions to all stackexchange.com.
I have fw/av up (Trend Micro) but no proxy. I have added an exception for stackexchange.com.

Is there a different domain I should add?

(The 's' in cookie[s] is no longer missing. Much more professional!)

We can't reproduce this. Do you have any other anti-virus, firewall, or proxy software running that would interfere?

With out of box default IE9 settings, everything should "just work".

  • I've further experimented with Trend Micro and essentially disabled most of its security features as well. I've also overriden the IE settings to always accept third party cookies... no luck! Any suggestions? Commented Jun 21, 2011 at 14:57
  • I will accept that this should work out of the box, as it seems to for most peeps. My particular problem, however, remains unresolved. This q continues to get views... perhaps people with a similar problem? Commented Jun 24, 2011 at 0:45
  • Please fix this, @Telis is right, I tried to create a StackExchange ID, and get the stupid 'Third Party Cookies Appear To Be Disabled' which is patently not true. Commented Aug 2, 2011 at 4:06
  • @lance still no repro; I just fired up IE9 and created a new openid.stackexchange.com account and logged in to pm, here, as this user: pm.stackexchange.com/users/1825/user1825 Commented Aug 2, 2011 at 7:49
  • Same issue here on Chrome and IE9 and with different Windows user accounts. Commented Sep 26, 2011 at 21:20
  • @luke check for any proxies, firewalls, or anti-virus software between you and us. Commented Sep 26, 2011 at 21:56
