The Auto-Complete list doesn’t remember names or email addresses

The Auto-Complete List is a feature which displays suggestions for names and email addresses as you start to type them. These suggestions are possible matches from a list of names and email addresses from the email messages that you have sent.

If names and email addresses that you enter aren’t saved to the Auto-Complete list, do the following:

If you're installing on Windows Server 2012, please make sure that you've installed the Windows Identity Foundation Windows feature on all Exchange 2013 Preview servers. If it's not installed, install it and then reboot the server.

If you're installing on Windows Server 2008R2 SP1, install the Windows Identity Foundation package from here -http://support.microsoft.com/?kbid=974405.
