I am trying to use the data type of: Microsoft.Exchange.Data.Unlimited(Of Microsoft.Exchange.Data.ByteQuantifiedSize) from within .NET 2.0. I can get evaluate a value such as MaxReceiveSize from but I can not create a new unlimited variable. This creates a limited value of 16320 Bytes Dim objByteQuantifiedSizeUnlimited As New Microsoft.Exchange.Data.Unlimited(Of Microsoft.Exchange.Data.ByteQuantifiedSize)(16320) Anyone know how to make this an Unlimited value in Exchange? Thanks.
