Lync Client Update Jan 2012 4.0.7577.4061 KB2670498

January Lync client update is out. Doesn’t look too exciting

Fixes this issue:

2670467  Large increases in load on the OrgID service because of recurring authentication requests from Lync 2010

“You notice that the ADFS server is experiencing larger than expected loads. These loads are more than 40 percent greater than expected. When you examine the traffic, most of the load is from recurring authentication requests from Microsoft Lync 2010. Lync 2010 is continually requesting OrgID tokens. This may be because of failed requests to Exchange Web Services (EWS). Each EWS request that Lync 2010 retries to send requires a new OrgID token, and the OrgID requests are causing the increase in authentication traffic to the ADFS server.”
