Outlook 2010 on Windows7 machines won't open email for one user but does for another.

The user's 2010 Outlook stopped connecting to the server while on the LAN.
After backing up the ost file as a pst and removing it and recreating the profile and uninstalling and reinstalling Outlook, I finally tried creating a profile for myself and everything worked fine. I still get the following error when trying to create the user's profile.

Cannot open your default e-mail folders. You must connect to Microsoft Exchange with the current profile before you can synchronize your folders with your Outlook data file (.ost).

Having created a working profile, I was able to CTRL-Rightclick on the Outlook icon in the system tray and test the e-mail configuration. When using my credentials, all works as expected. Here is a screen shot of the successful autoconfig:

When I use Erika's credentials (that same as used successfully to login to the laptop on the domain), the autodiscover fails with a series of 0x800C8202, 0x800C8203, and 0x8004010F errors as shown below:

This "test E-mail AutoConfiguration" for Erika fails on the laptop and on the only other machine I tried it on. Both machines succeed for the "Robert" account and two others I tried. This is all internal on the LAN. Erika can access her email via OWA and ActiveSync without any issues.

Here are my autodiscover settings according to my Exchange management Shell:

I also ran an Exchange Best Practices Analyzer Report which has one critical error: Site folder server deleted

Please help me fix it so Erika can use Outlook in the office.
