Skype for Business Client status sticks to Away

Few users complained about their presence status sticks to away and not changing except when they are in a call or meeting.

Tried all basic troubleshooting like checking from Skype for Business client end, Exchange connectivity (EWS) and all the settings seems correct.

Finally i have observed user has a virtual machine which has the same system configuration. It means two machines with a same host (One physical & One virtual)

When user logs into the virtual machine, the presence showing correctly.

After removing the VM machine & reformat of the machine. VM machine was configured with different host name & the issue is resolved completely.

Sfb client showing Lync instead of Skype for Business

After Sfb Client update with KB3101496 with the pre-requisite KB3101360
It started showing Lync instead of Skype for Business in UI & Task Manager

From Registry, I have changed the value of LyncName DWORD value from Lync to Skype for Business 
Computer\HKCU\Software\Microsoft\Office\15.0\Lync

But this seems to be a temporary solution as after the system restarts again it started showing Lync instead of Skype for Business

So, I have uninstalled the KB3101496 from my installed updates as the issue appeared after installation the Sfb client patch.

Finally after un-installation of the patch & restarting my machine, Sfb client started showing the name properly as "Skype for Business"

Can't sign in to Skype for Business

Issue: Can't sign in to Skype for Business Client

Description: The server is temporarily unavailable. If the problem continues, please contact your support team.

Collected the Skype client logs and observed there no messages recorded & only trace information available in Snooper Tool.

Below is the hint which i got from the log

SockMgr: Create New connection:DestName:(domain.com)DestPort:(5061)Transport:(2)httpTunnel:(0)TLS RemotePrincipalName:(domain.com)

Destination Name should be Skype for Business Front End Server instead of sipdomain.com

This issue would appear if user types domain.com in the Manual Configuration

To fix the issue, Just change the Manual Configuration to Automatic Configuration 

Checked in user client configuration and found in the internal server tab, domain.com was mentioned.
