Sign issue on skype for business 2015
We have Exchange 2010 and Lync 2010 on premise installed. We have just purchased Office 365 E3 plan and want to only configure Skype for business on our local lync/skype for business client for Office 365. Our domain already verified on Office 365 domain and we can use both .onmicrosoft domain or our verified domain.
The issue we are facing that when we enter user id credentials on skype for business its try to connect local Lync 2010 server not route to Skype for Business Online.
Kindly suggest what we are missing while configuring the Skype for Business on user skype for business client instead of connecting to Lync 2010 server.

Hi,

Can you please check your DNS records?
Can you confirm that Lyncdiscover.domain.com is pointing to the correct S4B Online records?

If you're using Lync 2010 clients, can you also confirm existence of _sipinternaltls._tcp.domain.com record? This is not required when working with S4B Online.
Additionally, if yo have sipinternal.domain.com or sip.domain.com records they should be removed as well.
