Lync online 2013 wont work domain users

Hello,

I had big issue with our customer Lync online login. Old IT support had move emails local exchange to Office365. But i they wont uninstall exchange 2007 only shutdown it.
domain user cannot now login to Lync online if computer is domain member.
but if i made new user account to domain that can login to lync online correctly with same computer. New user doesnt have AD attributes to exchange. If i login to computer with domain administrator also i can login to lync. Domain administrator has exchagen attributes. Problem is only with user what are in some OU.  i take gpresults txt to attach

Problem solved. Some of users had space in their account. space on domain username broke login to lync. There is no dirsync in use.

Do they have a SIP address? what is the error message they get when they try to login? Can they login from OUTSIDE of the domain environment?

They dont have SIP address on AD attributes. User can login outside of domain environment. Issue is somewhere in GPO. Because if I transfer user to another OU. new test account works fine, but old users wont work. Both OU had same group policy.

I take screenshot on login error.

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

This sounds like attribute sync issue! does the customer have SSO deployed? is there Dirsync that syncing to their office 365 tenant domain?

SSO and dirsync is not used. in AD attributes Proxy address doesn´t contains SIP address.

It doesnt need to, and if it works for the same users from outside of the corporate environment, the issue is most definitely not with the SIP address. As you are also saying that moving the user to another OU fixes this, can you check for any networking related GPOs? Firewall, proxy settings, dns resolution even. You can run the MOSDAL tool to collect some additional troubleshooting information:
