I´m working on a migration from Lync 2013 to SFB 2015, everything is working fine but OWA integration.
I followed all the steps for the integration and it seems to be fine, but when I check the service it is working but only to users that were created after the integration all the users that was on my AD prior this migration can't connect to skype via OWA.
I´ve searching all around and tried many solutions, even changing users properties on AD but that's not working, but if I clone an older user the new user can access to Skype via OWA so I can say it's not a profile problem but an AD problem, maybe this isn't
syncrhonizing with Exchange/SFB
Any suggestion?
