**Update - If you create your package and follow the instructions located under Add/Modify Shortcut (http://technet.microsoft.com/en-us/library/cc179097.aspx) you should be fine.**

One of my customers recently came across a weird error message launching the Lync 2013 client. They sent me an email saying after we deployed the Lync 2013 client in our environment we started getting the message below.

“The specified address is not recognized or does not exist. Please verify the address and try again. If you do not know the correct syntax for this address, contact your support team.”

They stated that if they clicked OK the Lync client would login and the message wouldn’t appear until they logged in again. Through some information gathering and troubleshooting we found that they packaged the Lync 2013 client using the Office Customization Tool (OCT). Through this package they created a desktop shortcut. This icon was the cause of the error message and if they launched Lync 2013 form the start menu icon the client launched without the error message. We are currently looking into how we can create this desktop shortcut without generating the error. I will update when we find a solution.
