Exchange Active Sync for Windows Mobile can cause some issues before it starts working. Most of the configuration issues are from IIS. A lot of times the error generated is: 0x85010014
Depending on your configuration there are a couple of way to tackle this issue.
Configuration 1 = Exchange Server without a Front End
If you do not utilize a Front End - Back End configuration, then Microsoft recommends that you follow these steps to fix the wireless sync issues:
Create a secondary virtual directory for Exchange that does not require SSL, and then add a registry value to point to the new virtual directory. To create a secondary virtual directory for Exchange that is based on steps 1 to 4 in the following procedure, make sure that forms-based authentication is disabled for the Exchange virtual directory before you make the copy. Before you follow these steps, disable forms-based authentication in Exchange System Manager, and then restart IIS.
Additionally, you must use Internet Information Services (IIS) Manager to create this virtual directory for Exchange ActiveSync and Outlook Mobile Access to work. If you are using Windows Server 2003, follow these steps.
Note These steps affect both Outlook Mobile Access connections and Exchange ActiveSync connections. After you follow these steps, both Outlook Mobile Access and Exchange ActiveSync connections use the new virtual directory that you create.
1. Start Internet Information Services (IIS) Manager.
2. Locate the Exchange virtual directory. The default location is as follows:
Web SitesDefault Web SiteExchange
3. Right-click the Exchange virtual directory, click All Tasks, and then click Save Configuration to a File.
4. In the File name box, type a name. For example, type ExchangeVDir. Click OK.
5. Right-click the root of this Web site. Typically, this is Default Web Site. Click New, and then click Virtual Directory (from file).
6. In the Import Configuration dialog box, click Browse, locate the file that you created in step 4, click Open, and then click Read File.
7. Under Select a configuration to import , click Exchange, and then click OK.
A dialog box will appear that states that the "virtual directory already exists."
8. In the Alias box, type a name for the new virtual directory that you want Exchange ActiveSync and Outlook Mobile Access to use. For example, type exchange-oma. Click OK.
9. Right-click the new virtual directory. In this example, click exchange-oma. Click Properties.
10. Click the Directory Security tab.
11. Under Authentication and access control, click Edit.
12. Make sure that only the following authentication methods are enabled, and then click OK:
• Integrated Windows authentication
• Basic authentication
13. Under IP address and domain name restrictions, click Edit.
14. Click Denied access, click Add, click Single computer, type the IP address of the server that you are configuring, and then click OK.
15. Under Secure communications, click Edit. Make sure that Require secure channel (SSL) is not enabled, and then click OK.
16. Click OK, and then close the IIS Manager.
17. Click Start, click Run, type regedit, and then click OK.
18. Locate the following registry subkey:
19. Right-click Parameters, click to New, and then click String Value.
20. Type ExchangeVDir, and then press ENTER. Right-click ExchangeVDir, and then click Modify.
NoteExchangeVDir is case-sensitive. If you do not type ExchangeVDir exactly as it appears in this article, ActiveSync does not find the key when it locates the exchange-oma folder.
21. In the Value data box, type the name of the new virtual directory that you created in step 8. For example, type /exchange-oma. Click OK.
22. Quit Registry Editor.
23. Restart the IIS Admin service. To do this, follow these steps:
a. Click Start, click Run, type services.msc, and then click OK.
b. In the list of services, right-click IIS Admin service, and then click Restart.
NOTE: Another method to verify that your exchange, OWA, OMA point to the correct backoffice path.
Configuration 2 = Front End and Back End Configuration
If you have a Front and Back End configuration for your exchange then follow the following steps to resolve your issue.
In the IIS Administrator make sure that both exchange virtual directories are not using SSL. Delete the SSL certs off the website (If exists). Then configure SSL ONLY on the Front End exchange virtual directory.
Check your AD user properties for Exchange and make sure you still have active synch enabled for your account.
