I will write a short post about connecting to Powershell endpoints of Exchange and Lync. Basically you can always use PSRemoting to connect and make use of modules. However some CMDlets will simply not work when importing the snapin or module. So connecting to an endpoint is much more efficient. To connect to Microsoft Exchange use the following commands:

$PSOptions = New-PSSessionOption -SkipCACheck -SkipRevocationCheck -SkipCNCheck
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ExchangeServer.Domain.TLD/powershell -SessionOption $PSOptions
Import-PSSession $Session 

To connect to Lync use the following commands:

$Session = New-PSSession  -ConnectionUri https://LyncServer.Domain.TLD/ocspowershell -Authentication NegotiateWithImplicitCredential
Import-PSSession $Session

You can connect from any domain computer. Of course if your loged on with an account that does not have to appropriate permission you’ll have to connect using the  -credentials parameter.
