EV 11 with SSL on W2k12R2 IIS??

Hi

i have some problems with the config of EV11 with SSL on our W12k2R2 server. With activated SSL ( i enabled require SSL on IIS on the EnterpriseVault folder with ignore client certs) i get

403 - Forbidden: Access is denied.

You do not have permission to view this directory or page using the credentials that you supplied.

The steps what i did are:

1. create a web certificate from our internal CA

2. create a new binding in IIS with port 443 and applied the certificat to that

3. on EV admin console activated SSL on port 443 for the whole site (we have two EV servers one on each site)

4. on the EV Server every https URL works fine like  https://servername.domain.local/enterprisevault/Search/Shell.aspx

But in Outlook the users get a 403 Forbidden error when SSL require is enabled on the EnterpriseVault folder in IIS. Windows Authentification is enabled for this folder / website. So without SSL everything works fine. I followed this guide here

So our target is that every internal communication to the EV from the Outlook clients goes over SSL. So i hope anbody can help me in this case.

Kind regards
