Lync Client Authenticaition

Here is a great article on how Lync Client authentication works, from both an internal and external perspective.

Amazed at some of the posts on the Lync NextHop website...

Lync 2013 Client Address Book Update

The Lync client by default will download the address book from the Lync FE server after a random amout of time once the address book is more that 24 hours old.

There is a Registry Key that can be updated to set the initial delay to 0 mins, in other words as soon as your local file is either: 

1. Not on the PC (has been deleted)
2. Or is more that 24 hours old

The following reg add is the key, its slightly different to from the 2010 client as Lync 2013 policies now reside under the office 15.0 side of things.

reg add HKLM\Software\Policies\Microsoft\Office\15.0\Lync /v GalDownloadInitialDelay /t REG_DWORD /d 0 /f

The address book files on the client are now also stored at a different location.

%userprofile%\AppData\Local\Microsoft\Office\15.0\Lync\sip_<lync_signin_address>

Lync Client Comparison Tables

I attended the Lync 2013 Ignite training the other week in Sydney and was keen to get some more information around Lync client capabilities.

Well Microsoft have published a nice little article on what each client functionality is:
