Unable to Login To Lync 2010
Hi experts.
I am getting serious troubles when I try to use Lync 2010 (https://www.microsoft.com/en-in/download/details.aspx?id=28177) from the OP+ edition to O365 edition.
Really, I am upset and depressed. I'm using the trial version of O365. If I am able to use Lync successfully, I would buy this software.
I have installed it a couple of times on my system, but it is still not running. I've searched the forums in this website and even looked on other sites. Then, I uninstalled and reinstalled it.
Still, I am getting the following error message:
Need to solve this. Thanks in advance.
Error:
