Activesync Error 86000107 and 86000104

The Activesync Errors of 86000107 and 86000104 are normally caused by changes to your Outlook folder structure which Activesync is unable to synchronize.  The following steps will recreate your Microsoft Outlook Mail Profile as well as your ActiveSync Profile.  Once you have recreated these two profiles, ActiveSync will regain its functionality.

Remove and Recreate Microsoft Outlook Mail Profile

1. Click Start - Control Panel - Mail Control Panel.
   
   
2. Click the Show Profiles button.
   
   
3. Select Outlook.
   
   
4. Click Remove.
   
   
5. Click OK.
   
   
6. Open Microsoft Outlook and follow the prompts on screen.

Import Existing Outlook PST File Into New Microsoft Outlook Mail Profile

1.  From within Microsoft Outlook, click File.
   
   
2. Click Import and Export.
   
   
3. Select Import From Another Program Or File.
   
   
4. Click Next.
   
   
5. Select Personal Folder File.
   
   
6. Click Next.
   
   
7. Click Browse.
   
   
8. Browse to the location of C:\Documents and Settings\[Your Username]\AppData\Local\Microsoft\Outlook.
   
   
9. Click Open.
   
   
10. Click Next.
    
    
11. Select Import Items Into Current Folder.  It is important that Current Folder is selected not the option of Import Items Into The Same Folder In Personal Folders.  If you make the wrong choice at this step, you will have to remove the Microsoft Outlook Mail Profile and start this process over.  Unfortunately, Microsoft Outlook defaults to the wrong setting so it is important to select Current Folder.
    
    
12. Click Finish.

Create The Windows Firewall Exceptions for ActiveSync

1. Click Start - Control Panel - Windows Firewall
   
   
2. Confirm that the following Windows Firewall Exceptions are in place.  If not, create them:

• C:\Program Files\Microsoft ActiveSync\WCESMgr.exe
  
  
• C:\Program Files\Microsoft ActiveSync\wcescomm.exe
  
  
• C:\Program Files\Microsoft ActiveSync\rapimgr.exe

Remove and Recreate ActiveSync Relationship Between Computer and Windows Mobile Device

2. Click the Hardware tab.
   
   
3. Click Device Manager.
   
   
4. Expand Network Connections.
   
   
5. Right-mouse click the Windows Mobile Device.
   
   
6. Click Disable.

12. Maximize Device Manager.
    
    
13. Right-mouse click the Windows Mobile Device.
    
    
14. Click Enable.
    
    
15. ActiveSync should then prompt you to recreate the relationship between this computer and the Windows Mobile Device.  Follow the prompts on screen.
    
    
16. Wait for the ActiveSync synchronization process to complete.  This may take some time.

If you find that the synchronization process completes successfully but that some items fail to synchronize - this is an indication that you have created multiple Contact Folders and/or Calendar Folders.  It is recommended that you use the single, standard Contact and Calendar folders created by Microsoft Outlook.
