Outlook 2010 new profile does not connect

Good Evening,
Intern tech logged on to machine as local admin and created an Outlook profile. Added RPC over HTTP proxy, installed certificates all worked.
However, user took ownership of machine, logged on as user and started to create the Outlook profile. Upon completion, Outlook continually requests credentials.
Outlook profile created under admin account still worked. However, OST was moved to user profile and still can't connect to Exchange.

We are now unable to delete Outlook profile from user login or recreate the Outlook profile under the correct login.

Must add that user is Dev manager that has local admin rights on PC.

Any ideas?

> When failing or repeatedly prompting for authentication, check for the Outlook-connection-status to see if the communication is in tcp\ip or https

> In the "Outlook Anywhere" settings, check if the msstd values
If you have the string "msstd:xxx.domain.com"
this value xxx.domain.com should be the issued-to name on the external certificate.

If not outlook will be prompted for the repeated authentication
If needed we have to use the command "Set-OutlookProvider"
