Lync/Skype4B Server: Manually update the Edge Server Configuration

In a recent support case we had a case that the customer had some urgency to add a new Allowed Domain to be quickly pushed to his Skype for Business 2015 Edge Servers.

However, the replication wasn’t working:

Get-CsManagementStoreReplicationStatus | ft -AutoSize


An easy solution to this is to perform a manual update and then fix the replication.

First, we need a copy of the latest configuration:

Export-CsConfiguration -FileName C:\UCLobby\


Now copy the file to each Edge Server and execute the following PowerShell cmdlet:

Import-CsConfiguration -FileName C:\UCLobby\ -LocalStore


Note: In this case we need to specify the LocalStore switch so it updates the local database.

This is also possible if we run, on each Edge ServerStep 1 from the Skype for Business Server Deployment Wizard:



Please note that manually updated the Edge Server configuration probably won’t fix the replication issue:


These steps are valid to Lync Server 2010/2013 and Skype for Business Server 2015.

This should be only use as a quick workaround to update the local store while we fix the replication issue.
