We have Internal users running Lync 2013 in a branch office that is filtered by the Hybrid Cloud service. When users launch their Lync client they are prompted to authenticate to the cloud. If they cancel out the login box, they are able to connect to Lync normally.
We have tried setting multiple Microsoft domains as an unfiltered destination as well as setting custom authentication settings to Auth Method - None for the domains.
Has anyone else run into the same issue?
Thanks.
