The function was successful. Check lpdwExtendedCode variable to get extended information.
E_INVALIDARG
One or more arguments are incorrect.
E_FAIL
Some error occurred in the function. Check lpdwExtendedCode variable to get extended information on the error.

Remarks

Delivery of message typing event can be disabled on the IM server so it is required to check that ESTABLISH_FLAG_TYPING_EVENT_DISABLED flag is not set returned by IServerClient::GetAccountInformation function.
It is recommended to send a message typing event for each recipient no more than once every 3 seconds to do not overload the IM server with such unused requests and data.
