I have been trying to find a solution for this problem everywhere. I am trying to sync my iphone to my work email, I can perform the setup on the iphone and it works fine but when I try to connect it says connection to server has failed. I've read something about the mailbox not creating the Microsoft-Server-ActiveSync folder so it won't sync. Here is the message the server eventlog gives

Unexpected Exchange mailbox Server error: Server: [TECNOSEDIA-DC1.tecnosedia.local] User: [] HTTP status code: [409]. Verify that the Exchange mailbox Server is working correctly.

Any ideas?

What version of iOS is your phone running. The newer the better for ActiveSync support. – Tatas Jan 5 '12 at 19:13
Have you setup any other mobile devices with your Exchange server? This will let us know if OWA is setup correctly. – Paul Ackerman Jan 5 '12 at 20:11

Does the user have the "Allow Mobile Access" bit set? (Must use the exchange ADU&C tool to set it... as the regular ADU&C is missing all of the exchange features)

I was able to get it working after deleting and reinstalling all exchange related Virtual Directories and running adsutil from the command prompt, then restarting Microsoft Exchange System Attendant. I can sync any mobile device with teh exchange server now.
