EWS FindItem with restriction works in Exchange 2007, not in 2010 RRS feed

  • Question

  • I have an application writtten in VB.net and it works with Exchange 2007, but when run against a 2010 server fails.  Specifically, what I'm trying to do is a restriction (search) based on start date and end date.  Here is part of the code:

                  StartDateReceivedToGet.Value = EndDate.ToUniversalTime().ToString()
                   Debug.Print(Now() & ": Start date UTC: " & EndDate.ToUniversalTime().ToString())
                  Dim StartDateReceivedConstant As New FieldURIOrConstantType()
                  StartDateReceivedConstant.Item = StartDateReceivedToGet
                  Dim igtett As New IsGreaterThanOrEqualToType()
                  igtett.FieldURIOrConstant = StartDateReceivedConstant
                  igtett.Item = StartDateReceivedField
                  'restrict the returned items less than a specified date
                  Dim EndDateReceivedField As New PathToUnindexedFieldType()
                  EndDateReceivedField.FieldURI = UnindexedFieldURIType.itemDateTimeReceived
                  Dim EndDateReceivedToGet As New ConstantValueType()
                  EndDateReceivedToGet.Value = StartDate.ToUniversalTime().ToString()
                  If LogLevel > 0 Then
                    ThreadLogFile.WriteLine(Now() & ": End date UTC: " & StartDate.ToUniversalTime().ToString())
                    If LogLevel > 1 Then
                      LogFile.WriteLine(Now() & ": End date UTC: " & StartDate.ToUniversalTime().ToString())
                    End If
                  End If
                  Debug.Print(Now() & ": End date UTC: " & StartDate.ToUniversalTime().ToString())
                  Dim EndDateReceivedConstant As New FieldURIOrConstantType()
                  EndDateReceivedConstant.Item = EndDateReceivedToGet
                  Dim iltett As New IsLessThanOrEqualToType()
                  iltett.FieldURIOrConstant = EndDateReceivedConstant
                  iltett.Item = EndDateReceivedField
                  Dim at As New AndType()
                  at.Items = New SearchExpressionType(2) {}
                  at.Items(0) = igtett
                  at.Items(1) = iltett
                  ' Create a restriction type
                  Dim restriction As New RestrictionType()
                  ' Add the search expression to the restriction.
                  restriction.Item = at
                  ' Add the restriction criteria to the findItem request.
                  ' findItemRequest.Restriction = restriction
                  'Find the messages within the specified date range
                  Dim FIAttempts As Integer
                    Dim firt As FindItemResponseType = esb.FindItem(findItemRequest)
                    For Each firmtMessage As FindItemResponseMessageType In firt.ResponseMessages.Items
                      Debug.Print("Number of messages found for folder " & Folder.DisplayName & ": " & firmtMessage.RootFolder.TotalItemsInView.ToString)

    Start date value provided is 1/1/1990 6:00:00 AM



    End date value is 9/3/2010 10:21:07 PM

    So when I execute the code in against an Exchange 2007 server, it works perfectly every time.  When I execute this same code against an Exchange 2010 server, it fails.  COMMENTING OUT the restriction, running this code against the 2010 server then works.

    The exception I receive is "The specified value is invalid for the property" when trying to read firt.ResponseMessages.Items.   

    Did the date format change between versions for this FieldURI?  Any help would be appreciated.

  • I had the same kind of problem but I've found a solution that works form me. Try to format Your date like this EndDate.ToUniversalTime().ToString("yyyy-MM-ddTHH:mm:ssZ"). Earlier my date format was "yyyy-MM-dd HH:mm:ss" and it worked on Exchange 2007, but not 2010. Now It works on both versions.
