    • If you are running a 64-bit operating system, replace "Program Files" with "Program Files (x86)" in the path.

    • Replace Office14 in the path with the version of Office that you are running.

  3. At a Command Prompt, run the following command line:

    C:\Windows\Microsoft.NET\Framework\v2.0.50727\RegAsm.exe "C:\Program Files\Microsoft Office\Office14\Microsoft.Dynamics.NAV.OLSync.NAVSyncAddIn.dll"

If you receive the following error message for a salesperson, make sure that the email address in the contact item is either typed manually or else synchronized from Microsoft Dynamics NAV:

The related item for the synchronized Outlook item is not found

This problem is related to the salesperson contact item that is linked to the global address list. The salesperson contact item is not allowed to link to the global address list. This problem can occur when you set the mail address for the contact in Outlook instead of in Microsoft Dynamics NAV. Under typical circumstances, by using the newest version of the .dll file, you can set the email address in Microsoft Dynamics NAV and then synchronize the email address to Outlook.


You must have one of the following products installed to apply this hotfix:

  • Microsoft Dynamics NAV 2009 R2

  • Microsoft Dynamics NAV 2009 Service Pack 1


Microsoft has confirmed that this is a bug in the Microsoft products that are listed in the "Applies to" section.
