Hello Forum,

In the Last Few days i wanted to Experiment around with some old systems to see how they worked.
(I wanted to work a Month in an Old Style doing nothing Important)

I am Having Trouble Setting up a Lync 2010 Server Mobile Connection. On my Android 11 Device
i installed an App to Open the Lync 2010 Mobile Settings, that is not the Issue. However when i am Connecting i receive:
"Unknown Error/Problem. Try Again Later." (I am German, it is a Rough Translation).
So i went and Checked with 2008 R2 and checked all Patches and Services were installed and Running, which they were.
The Phone is also in the Right Network Space.

I checked the Lync Mobile Log and it says it is actually trying to Connect to the Temporary Local IP. (192.168.0.253:443 / 192.168.0.253:4443)
It is receiving a Problem which is a 403 IIS Error.

On my 2003 and 2012 R2 machine it is reporting the Same.
PS: I know these Systems are all EOS / Almost EOS. It is just for Fun but i really would like to see it....

Thank you for Suggestions,
Maximilian Schäfer, greetings from GER M8s
