How can I get the number of users actively using Lync?

Question

How can I report on the number of users actively using Lync in my organisation? I want to be able to find out what the uptake is.

Thought about going through our mail server, but the saved conversations don't go via SMTP. Also wondered if there's a Powershell way to get the date of the last login / last conversation.

I'm using Lync 2010 via Office 365.

Solution

It's not very impressive but for Lync Online you can use the Get-CsActiveUserReport to show the number of active users per tenant on a daily, weekly, monthly or yearly basis

It only works for Lync Online (O365) and I'm not sure how factors in users using on-premises servers

Do you have administrator rights over the Exchange/Lync server ?

Yes I do. It's O365 (online) with one on-premise server.
