I have made an application which sends IM to the buddy (contact) using RTC ver 1.3.Though its working properly but after some time it throws a exception as
System.Runtime.InteropServices.COMException (0x80EE0061): Exception from HRESULT: 0x80EE0061
at RTCCORELib.RTCClientClass.RemoveBuddy(IRTCBuddy pBuddy)
Please resolve this issue.
regards,
