An appeal for help.
We are having an issue with the client driven PST migration feature in EV 11 constantly prompting the user for authentication, even if the user does provide credentials the prompt reappears.
If we disable the Client Side migration feature EV works just fine no user prompts at all!
The error appears to be with the path https://EVServer01:443/EnterpriseVault/ReadPstFiles.aspx
from th Event viewer on EVserver (I have changed my domain name details for this post)
Event code: 4011

We are using IE11 on windows 7 machines with exchange 2010 in one domain.
What I can confirm so far.
The EVServer name and alias (FQDN) is present in local Intranet . I added the IP address of the EV server for good measure. Protected mode is switched off and Automatic logon only in intranet zone is set under the User Authentication setting.
Turning the proxy server on and off has not made any difference, I also added the EV sever as a proxy exception (just In case)
I tried the following in order reverting config after each step but still get the login prompt. Every time tested something I closed outlook on the test machine, opened performed sync then clicked the .PST migration button which always triggers the prompt.
• Disabling the authentication settings for ReadPstFiles.aspx between basic and IWA.
• Changing the permissions on the ReadPstFiles.aspx to everyone full control (at present EVServer users have read and execute).
• Removing the requirement for SSL from the EV site in IIS
I have also tried changing the providers in windows authentication between negotiate and NTLM on the root of EV in IIS and just the directory pointing at ReadPstFiles.aspx I can see switching the methods does actually change as the authentication details are in the event log but no lot up on the user prompts.
I can see someone had the exact same issue here, but there isn't any solution:

Any help or suggestions much appreciated.
