BIS validation Exchange 2010

Hi All,


Currently I'm using Exchange 2010 and publish OWA using TMG, I also add a path EWS at the TMG listener. Then I want to add a BIS account, when I create it in the office hours till let say 11:00 PM it keep saying validation error. 


But strangely if I validate early morning at 3-5 AM it works. My colleague confirm it too when he tried it, almost all the user having the same experience. I tried with different provider too, same issue.


Any ideas ?

Welcome to the forums. 


Have a look at this KB article as I think it will explain what is happening with your account.
