NAV 2009R2 - Outlook Synchronization Filter Error

Hello,

I'm trying to get Outlook Synchronization working in NAV 2009R2 NL with Webservices and Outlook 2007 SP2 (Dutch Localization for Outlook Add-in "OutlookAddIn.Local.Nl.msi" installed).

For a start i did use the "Walktrough: Setting Up Outlook Synchronisation" found on MSDN (http://msdn.microsoft.com/en-us/library/dd338966.aspx).

To keep it simple at the beginning i only synchronize contacts.
Running the synchronization from Outlook without filters acts like expected: it works fine!

But:
Setting Conditions for the Contact Entities in Nav results in an error message on the synchronization from Outlook:
NST Asynch Call completed with Error: A '=' is missing in TransferFormulaData. WHERE(Verkoper=CONST(NAVDEMO),Type=CONST(0));

Trying to solve the issue i did use the "Troubleshooting: Microsoft Office Outlook Integration and Synchronization" document also found on MSDN (http://msdn.microsoft.com/en-us/library/dd983823.aspx). I verified several things, including the section "Configuring Microsoft Dynamics NAV Synchronization Add-in on Localized Versions of Microsoft Dynamics NAV"

Further on I found out that the language for the Outlook Add-in NST session via Web Services is determined bij the language selected in the last Classic/RTC session of the applicable user (which can be found in Table 2000000073).
After starting Nav Classic with the same windows user account as used for Outlook and setting the language in the Nav userinterface to Dutch the NST error message was translated to Dutch!
Still i got stuck with te following error message:
NST Asynch Call completed with Error: Een '=' ontbreekt in TransferFormulaData. WHERE(Verkoper=CONST(NAVDEMO),Type=CONST(0));
Hope so anyone can help me on this issue.

Best regards,

Cees
