I am specifically interested in the OUTLOOK Meeting information and NOT ONLINE MEETING.
Can I GET the outlook calendar meetings (along with its details: time, subject, location, attendees, etc) using UCWA.
I asked about the same on UCWA forum of MSDN, and came to know that it isn't possible via UCWA. However, this raises another question: As a Lync user, if I hover my mouse over a contact who's busy in a meeting, then it shows the time until when he/she is busy, for example "Busy until 2 p.m.".
How is Lync fetching this outlook meetings information and displaying the output as per the meeting time. How does this mechanism work?
Lync/Skype for Business clients are making requests via Outlook APIs to grab non-online-meeting events to display that data. You would need to design your application to sign-in to their Outlook account and make use the available Outlook APIs to get all the meetings/appointments that are not present in Lync/Skype.
