Hi All,

 We are on Lync 2013 and my client want me to disable the feature where, the user can logon to Lync from multiple workstations. If a users was already logged in to one workstation, it should sign him/her off from the workstation when he logges on to other workstation.

Hi

Unfortunately by design Lync allows sign in to multiple clients, although the last client login is treated as the active one. I don't think you can send a sign-off message to the inactive client when you sign on another device. What you would need to do is perhaps limit user login to one windows machine at a time rather than limiting the Lync application itself

There used to be a windows tool built by the community called limitlogin but not sure if it works on Server 2012 Domain Controllers. Other than that you would have to use third party controls for that.

I'm looking for a configuration which existed on OCS 2007

https://technet.microsoft.com/en-us/library/dd572363(v=office.13).aspx

is there such a configuration in Lync 2013?

Presence Policies in Lync 2013 are contained in XML files

Not sure this will do what you asked though, but give it a go.

Hi Channavera,

1. "I'm looking for a configuration which existed on OCS 2007" this is not pointing towards what you had asked in the initial post.

2. I would like to know the reason behind this request. "it should sign him/her off ".

Why?  The session already automatically becomes inactive and presence will be tracking the current session as active all pings will be redirected to the active one and the inactives will be as it is will not effect or consume network bandwitdh as well.

No other application seem to allow you to logoff, be it email or Windows OS on multiple devices.

Hi channavera,

This should do the trick, you might need to add OWA and FE server names as well for it to work.

List out the workstation name : logon to workstation

The Logon To option is in the  User Properties dialog box.

Active Directory: Workstation Logon Restrictions (Log On To)

https://support.microsoft.com/en-us/kb/160783#/en-us/kb/160783

I think the OCS equivalent setting you're looking for is MaxEndpointsPerUser: https://technet.microsoft.com/en-us/library/gg398764.aspx?f=255&MSPPError=-2147217396

The command would look like this

Get-CsRegistrarConfiguration | Set-CsRegistrarConfiguration -MaxEndpointsPerUser 1

However I would NOT recommend running this.  It doesn't behave exactly as you expect.  The issues are that if you attempt to log into a second device, the first does not log out.  Instead the new device gets an error saying too many devices are connected already.  On top of that, hung sessions are possible, if a client crashes or someone slaps a laptop closed without ending the session, they may not be able to log back in again until a timeout is reached killing the old session.

There is nothing in the product that would allow this to happen automatically.  You can limit the number of workstations/devices for a single person to 1 but that won't log them out of the other machine automatically, it would simply prevent them from logging in.

You would need to write some sort of process to revoke the users certificate and hope that removes from the server. Not sure how else you would be able to automatically log someone off.

Hi

I have tested it. After you set the parameter MaxEndpointsPerUser to 1, you can login Lync client on the second computer. The previous logon will get the error The server is temporarily. If the problem continues, please contact your support team.
