Lync 2013 and Exchange fix.

Project Description:

Hi I need to get lync server 2013 fixed the problems it has hit this:

1) Cannot connect to it outside network, I think small firewall problem with a little problem in server.

2) it cannot link with exchange for storing messages

3) with lync mobile (when it was working ) it always ay server reconfigured and you have to relogin it kills everyone phone battery and makes it unusable.

lync was working for issue before then we moved our servers to new datacenter and it broke. The problems with exchange are :

1) the search in OWA isn't functioning right.

2) users can't change their password with OWA

3) if an account requires user to change password on next login it does not let them login with OWA

Skills required are Microsoft Exchange, Windows Server, System Admin
