Make sure that the TMG firewall have ports 443,3478 and 50000-59999 open to all traffic.

are you using proxy credential to access internet ?

if yes then changed with Un-authenticated access

Dear Haresh Nikumbh,

we are using proxy to access internet, so how to change to Un-authenticated access?



Dear vasilcho,

what we have is a Lync on-promise, not online...

Nothing ever in the clear!

This technical paper will help you implement VMware’s VM encryption as well as implement Veeam encryption which together will achieve the nothing ever in the clear goal. If a bad guy steals VMs, backups or traffic they get nothing.

It's not a simple fix.  Easier solution would be to bypass the proxy server if possible, ie, use Lync Mobile Client instead.
