We have a Lync Server Installation with the lync + cucilync client.
We also installed the Click to Call Addin to all Office Programmes.
The Click to Call Button in Outlook works fine when I want to call somebody from the Outlook Contacts.
But when I want to call somebody who send me an email the button doesn't work.
Even when I have the email sender in my outlook contacts it still doesn't work.
Can anybody help me to fix that problem ?
