Lync 2013 Distribution Group is too large to display

Hi!

Running Lync Server 2013 SE. Distribution Group size : 120.

How can I increase the limit for a Lync 2013 client to show more than 100 members in a distribution group?

I already increased the limit on the webservices to 150 by running:

Get-CsWebServiceConfiguration | Where-Object {$_.EnableGroupExpansion -eq $True} | Set-CsWebServiceConfiguration -MaxGroupSizeToExpand 150

But the Lync 2013 client still says "Distribution Group is too large to display. Lync cannot be used for groups with more than 100 members." I can expand the smaller groups +- 20 users.
