evolution fails to Authenticate in Microsoft Exchange Assistant dialog

Binary package hint: evolution

I'm using the Account Assistant dialog to setup a Microsoft Exchange account.

Using:

Username: Domain\Domainuser
OWA URL: http://owa.company.com/exchange
Mailbox: <email address hidden> (which is the same as the email I set for the account, except capitalization, I tried with and without filling out this field)

Getting message, "Could not connect to server. Make sure the URL is correct and try again"

Here is the console debug message (starting as E2K_DEBUG=5 evolution):

e-data-server-ui-Message: Unable to find password(s) in keyring (Keyring reports: No matching results)
e-data-server-ui-Message: Key file does not have group 'Passwords-Exchange'
> GET /exchange HTTP/1.1

> Host: owa.company.com
> Accept-Language: en-US, en
> Authorization: NTLM TlRMYYYYTUAABAAZZZZZZZZZZZZZZZZZZZA
> User-Agent: Evolution/2.24.1

There are some similar bugs reported, but in those cases the users were able to authenticate, then manually change configuration as a workaround.

Thanks
