To fix error 85010014 on a front end/backend Exchange configuration,
don't enable Integrated Windows Authentication on the Exchange Virtual
Directory on the front end server especially if you are using SSL, this
will break OWA.  On the front end only have basic authentication check
and then have SSL required at 128-bit.  On the backend exchange server
(this is where OMA actually gets your mail), Enable Integrated Windows
Authentication & basic authentication, but don't have SSL required
(that will break the connection between the front and back end
servers).

On Back End Server:
1) Log onto the Exchange server
2) Open IIS
3) Goto the "Exchange" virtual folder -> right-click -> click on
"Properties"
4) Click on "Directory Security" tab
5) Click "Edit" (under Authentication and access control)
6) Enable "Integrated Windows Authentication"

That's it.  If you have any questions, please let me know.
