OWA 2007 – Error on page IE8+ Unable to create new Email or Open an email – Cannot open an anonymous level security token.

I found the information on a Microsoft Forum, sorry I don’t remember the link, I just copy and paste the answer.

I am routinely getting this message after installing IE 8. The message occuring on random sites, mainly in scenarios where a pop up window should open (or open code is called in javascript). I’m not sure what is causing it, or how I can get it to stop happening. Does anyone know what this could be related to?

Message: Cannot open an anonymous level security token.

I did find a page on msdn talking about the issue, but it said something about “raising the identity level”. I’m not sure how to do this or if it’s even related.

I found the answer to the same problem on my laptop. It was in the DCOM settings. You can type “dcomcnfg” at the run prompt, expand “Component Services” and right-click on the “My Computer” to get to properties. From there choose the “Default Properties” tab and change the default authentication level to “Connect” and the Impersonation level to “Identify”.

Worked for me.

My problem was caused by some Lenel Video software that made changes to the local machine DCOM settings.
