MS Exchange 2010 stopped accepting Active Synch connections from mobile devices. The reason is bad username/password which is not the case here. In addition OWA does not allow deleting emails, error "Your network connection isn't available. If the problem continues contact your helpdesk with this HTTP Status code:302." (Displayed in Google Chrome). The same error is present in MSIE, however Status code is 0. This is true for internal, external and localhost access.

It may have to do with authentication settings, this is what's currently set up on the server (IIS)
There are 6 authentication methods available:
Anonymous Auth
ASP.NET Impersonation
Basic Auth
Digest Auth
Forms Auth
Windows Auth

I am listing only enabled settings
Default web site: Anonymous
aspnet_client: Anonymous
autodiscover: Anonymous, Basic Auth, Windows Auth
ecp: Basic Auth
ews: Anonymous, Basic, Windows
Microsoft-Server-ActiveSynch: Basic
OAB: Windows
owa: Basic
powershell: Anonymous

Changing passwords, restarting IIS, removing wwwroot\web.config didn't help at all.

Appreciate any help.
