Enterprise Vault - PST Import button prompts for authentication
I am preparing for a company roll out of EV client and will be using the PST imnport feature. During initila deployment to 20 machines - 3 out of 4 users enabled for PST import are prompted for credentials when clicking the PST button in EV toolbar and also at intervals during normal Outlook usage.
The one machine where this is working has allowed me to make a comparision of network streams using wireshark to analyse capture from netMon.
The key seems to be that a session cookie is not being set on the machines that have this issue. The issue is machine based as it stays with the machine independent of the users that logs on.
The below is a comparison of 2 tcp streams - the left one on 484 works and the cookie is being set - the right hand causes the authentication popup to be displayed and no cookie is set.
I have checked all IE settings and permissions for cookies and removed all group policies from test machine & reset IE to Defauts etc.., but still get this issue. I am at a loss to find differences between these 2 test machines as they have the same build.
Outlook 2010, EV 11, IE11 and IE9, Exchange 2013 (In exchange resouirce forest)
Really need some help here!
