Lync 2013 Distribution Group is too large to display RRS feed

  • Question

  • 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.

  • Hi Raju.

    That doesnt work for Lync 2013.

    There isn't a [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Communicator] key for Lync 2013 Client or Server. Also no other key that seems related to Lync 2013 - do you maybe know where I must add those DWORD values (they key path) ?

  • Hi,

    You can try to manual add this key in HKCU:\Software\Microsoft\Office\15.0\Lync

    What Lync 2013 client setting are held in the Registry:

  • Hi Kent-Huang

    Thank you for responding.

    I have manually added the below entries to the HKCU:\Software\Microsoft\Office\15.0\Lync registry key on the client machine:

    "MaxDLExpansion"=dword:00000200
    "MaxConferenceSize"=dword:00000200

    I've exited and opened the Lync 2013 client and still get the same error "Distribution Group is too large to display. Lync cannot be used for groups with more than 100 members."

    Any further suggestions ?

  • I don't know if its still relevant,

    but i found that the "MaxDLExpansion" should be created in the following path in order for it to work: (I had to exit and reopen the client)

    HKLM\Software\Policies\Microsoft\Office\15.0\Lync

    The maximum limit is still 150.

    Hope that helps.
