I've created Lync meeting URL using Lync API 2010, and now I also want to set Lync URL expiration period using Lync api can anybody help me to solve it out ?
Expiry period is set in the ConferenceScheduleInformation class.
You can either specify this when you create the conference, or you can update the conference passing in the updated ConferenceSCheduleInformation class using the BeginUpdateConference method.
