Outlook 2011 - Error Code -17997

I have set up Mac Outlook 2011 to connect to our Exchange 2007 server.  The first Exchange account connects without a problem, but their are two more accounts on the server that I need to connect to.

I can add the accounts, but get a yellow light next to the accounts when connecting them.  The settings I use are:
Authentication: 
  - method: user Name and Password
  - user name: <full e-mail address>
  - password: <proper password)
Advanced, Server Tab:
  - Microsoft Exchange
       - Server: <fully qualified domain name, which I can connect to through a browser using https://webmail.domainname.com>
       - Use SSL to connect
  - Directory Service 
       - Server: <the internal address of our domain controller>
       - <checked> Login with my Exchange credentials
       - Search Base: "dc=<companyname>, dc=com"

When I try to send an e-mail, I get a message that "Unexpected data was encountered."  When I go into the error log, I see that "mail could not be sent" with the error code -17997. 

Can someone help?

Had this problem on my Mac Air with Outlook 2011.  Solved the problem but it was a server-side solution.

Had to rebuild the virtual directories on the Exchange Server 2010, apparently that's a known problem.  In order to do that thru the Exchange Management Console had to upgrade the server to SP3.  Then could use the GUI to rebuild each of the IIS virtual directories.

That solved it!
