I'm trying to return a single calendaritem from Outlook from our C# windows desktop application. It keeps returning this error: Redemption.RDOItems Assertion failed: Number of fields == 1.

I use similar code in an Outlook addin I created and it works fine. The main difference is the filterprefix. In the AddIn I use:

string filterprefix ="[" + OurCustomProperty.OurItemId + "] ='";
var filter1 = filterprefix + parentItem.NeedlesId + "'";

var findItem = folder.Items.Find(filter1);

but this code does not work from our desktop app.

Here is the code from the desktop App which is returning the error:

The appointment.Id contains a valid value which we set when we create the item.

string Filterprefix ="@SQL="+"http://schemas.microsoft.com/mapi/string/{00020329-0000-0000-C000-000000000046}/OurCustomProperty.OurItemId/0x0000001f ='";

RDOSession rdoSession = new RDOSession();

rdoSession.Logon("", "", false, false, null, false);

RDOFolder folderRDO = rdoSession.GetDefaultFolder(rdoDefaultFolders.olFolderCalendar);

var filter1 = filterprefix + appointment.Id + "'";

string ls_find = Filterprefix + appointment.Id + "'" ;

var findItem = folderRDO.Items.Find(ls_find);

I've tried several variations of the syntax but can't seem to get it right. I also tried using Sort then Restrict but no luck with that either.

Thanks, Rick

RDOItems.Find takes a SQL statement, please do not use the @SQL= prefix - it is OOM specific. Also do not forget to doublequote the DASL property name:

"http://schemas.microsoft.com/mapi/string/{00020329-0000-0000-C000-000000000046}/OurCustomProperty.OurItemId/0x0000001f" ='<some value>'
