Hello,
I am new to Lync and Lync was set it up before I arrive to my company so I tried to learn as much as I can but still my knowledge is not enough to solve this issue below.
Suddenly this week Lync Client & HP 4120 phones stopped showing Call Logs and Calendar. If I go to Outlook under Conversation History I can see all the logs but it says Connection to Microsoft Exchange is unavailable on the phone screen. I've checked all the services running and follow so many instructions to fix this issue but nothing. I can see that EWS Information is showing as not deployed on Lync Configuration Information window and I think this is why I lost all the log information.
I cannot update these HP phones as well, there is no activity when I try to update them using Lync CSCP putting the mac address etc. But this is another issue to be checked later, I am just writing this if it's related.
Any suggestions?
