Troubleshooting Exchange ActiveSync and OMA errors

Event ID 1507, 1805, 3029, 3030 and 3031

Symptoms: 1. When using Exchange ActiveSync, you will receive following errors: 1) “Your account in Microsoft Exchange Server doest not have permission to synchronize with your current settings.  Contact your Exchange Server administrator. Support Code :  0x85010001” 

2) "Unable to connect to your mailbox on server Servername. Please try again later. If the problem persists contact your administrator."

3) "A System error has occurred while processing your request. Please try again. If the problem persists, contact your administrator."

4) "Synchronization failed due to an error on the server. Try again. Error code: HTTP_500"

2. The Event Viewer lists Event ID 3005 - Unexpected Exchange mailbox Server error: Server: [mail.chicagotech.local] User: [bob@chicagotech.net] HTTP status code: [503]. Verify that the Exchange mailbox Server is working correctly.

3. Or Event ID 1805 - Request from user UserA@domain.com resulted in the Microsoft(R) Exchange back-end server <ServerName> returning an HTTP error with status code 403:Forbidden.

4. Event ID 1507 - An unknown error occurred while processing the current request: Exception of type Microsoft.Exchange.OMA.DataProviderInterface.ProviderException was thrown.

5. Event ID 3029 - The mailbox server [%1] has its [%2] virtual directory set to require SSL. Exchange ActiveSync cannot access the server if SSL is set to be required.

6. Event ID: 3030 - The mailbox server [%1] has forms based authentication enabled on its virtual server. Exchange ActiveSync cannot access the server when Forms based authentication is enabled.

7. Event ID 3031 - The mailbox server [%1] does not allow "Negotiate" authentication to its [%2] virtual directory. Exchange ActiveSync can only access the server using this authentication scheme.

Resolution: Exchange Server ActiveSync and Exchange OMA use the Exchange virtual directory to access the user's mailbox which is located on OWA templates and DAV on Exchange back-end servers, Exchange running on SBS 2003 or single. Server ActiveSync and OMA must access this virtual directory, /exchange-oma. So you need to make sure ExchangeVDir points to /exchange-oma.

To fix these issues, create a secondary virtual directory, for example /exchange-oma, for Exchange that does not require SSL, and then add a registry value to point to the new virtual directory.
