Connection to Exchange is unavailable due to invalid network credentials. Do you want to sign out and sign in again using your computer?
After upgrading to the latest Lync Phone Edition version 4.0.7577.250 (Apr 2011 “CU2″), a domain-joined machine teathered via USB to the device started experiencing the error above (Exchange Web Services is unavailable). This is regardless of how and the number of times a Lync-enabled user attempts to sign-in i.e. Domain\User, Domain.com\User or user@domain.com at the Strong User Authentication (SUA) prompt.

Update (Nov 2012)
The techniques described here apply as well to determine which version(s) of Lync Server 2013 server roles and services is/are currently installed. This can be enhanced with the handy PowerShell WMI method:
$product = “*Lync Server*”
Get-WmiObject -ComputerName $computername -query `
“select * from win32_product” |
where { $_.name -ilike $product }

At the top right hand corner of the Lync Server Control Panel, you will find the version of Lync Server being shown below the name of the signed-in user. Using the Lync Server Management Shell, a couple of cmdlets can be executed to determine the version information.
