Disable external access for lync 2010

We have a lync setup that has 2 edge servers and some internal lync servers. We need to disable external access so no one in the company can just start the lync client and connect in, but we need to keep federation access working.

How can this be done.

If a user is licensed for the Lync client then I dont think you can stop them using it externally IF you have federation setup.  I may be wrong but I have certainly not come across any way that this could be set in Lync 2013 that we use.

You need to change the External Access Policy on the link enabled user within the Lync Control Panel. You can do this from an individual user stand point.

This is also a default setting that you need to apply when you first enable a lync user account.

Do this from the Lync Admin Control.

So In the lync admin console, I see under "external user access" there is Federated user access, remote user access and public provider access.

Now if I want just my user that are on our network and federated users to access our lync, do I uncheck remote user access and public provider access?  Confused on this one.

Public provider means Office 365, yahoo, skype..etc so if you disable the Public providers then you won't be able to connect with Skype users or Office 365 Lync online users ..etc

If you disable Remote user access, then your users won't be able to access Lync remotely through the edge server.

for your choice you will only have to leave the option "Enable communications with federated users" enabled for your users.

If you don't want to confuse your self I suggest you disable everything on the Global policy except "Enable communications with federated users" and make sure that all users have the global policy set on their settings.

ok, so by unchecking all on global but "federated user access" all my users will have access will on our network and access to who has been federated?

Where do I set "global policy set on their settings"

You will need to open Control panel > Federation and External Access. on the right pane under "External Access Policy" double click on the Global policy there. and make sure you untick all the options there except the "Enable communications with federated users".

When you do these changes, make sure your Lync front end is replicating properly to Edge for the changes to take effect.

You can force replication by launching Lync Management shell and enter the cmdlet

Invoke-CsManagementStoreReplication

To make sure your replication between Edge and FE is working, from Lync Control panel go to Topology and check the status of replication next to Lync Edge servers. If there's a a green right mark then your replication is working fine.

Make sure you also change the user's External policy to Global.
