This is pretty nice update since it is adding in updates for coexistence and cloud hybrid and cloud only scenarios if you looking at our cloud offering for Exchange Online.
Here is a checklist for moving to the Office 365’s Exchange Online:
Updated Coexistence checklist for deploying Exchange 2010 with both Exchange 2003 and Exchange 2007:
Visit the Exchange 2010 Deployment Assistant tool here.
Two new chapters have been posted to the Kit. One on Direct SIP and the other on Exchange Unified Messaging integration. Direct Session Initiation Protocol (SIP) provides SIP trunking between an IP-PBX and Lync Server.
Direct SIP supports the following use cases:

This has been a hot topic for some of my customers and I’m very happy to see it’s release. The whitepaper for Client Virtualization can be found here.
Products from both Microsoft and Citrix are detailed in the paper including Remote Desktop Services (RDS), App-V, and Citrix’s XenDesktop and XenApp. The paper goes on to describe 3 different options for virtualization Full Desktop Remoting, Application Remoting, and Application Streaming.
…cut/paste from whitepaper…
Full Desktop Remoting
Application Streaming 
Sharing PowerPoint Presentations
Desk phone paired using USBR
 Application Streaming was verified on Microsoft products. For details, see the “Vendor Support” section earlier in whitepaper. Audio is supported only in a VDI environment. Audio is not supported in a session-based desktop delivery environment such as Microsoft RDS. Communication modes for Online Meetings are limited by peer-to-peer communication modes supported for the specified architecture. For example, if audio is not supported on the specified architecture, audio will not work in Online Meetings. Joining online meetings from Microsoft Outlook meeting reminder and/or meeting invitation is not supported.
Updated 5-20-11 with new independent security tests against Lync Server 2010
I sometimes get asked by telecom teams how secure is the voice traffic in Lync and is the conferencing traffic secure both on the internal network or externally. Note: diagrams and a few excerpts taken from our whitepapers
What type of secure communications are used with Lync?
Server to server Lync Server 2010 communications is encrypted by default. By requiring all servers to use certificates and by using Kerberos authentication, TLS, Secure Real-Time Transport Protocol (SRTP), and other industry-standard encryption techniques, including 128-bit Advanced Encryption Standard (AES) encryption, virtually all Lync Server data is protected on the network.
Lync Clients to Server traffic uses TLS for SIP traffic and SRTP for media such as audio, video and desktop sharing.
The following is a matrix showing the secure traffic types:
This diagram from the whitepaper shows how clients communicate securely using audio and video SRTP and TLS and Lync servers communicate securely with MTLS
Can someone sniff the packets and get access to my Lync voice/data?
By using TLS it would render a sniff/man in the middle attack very difficult to impossible to achieve within the time period in which a given conversation could be attacked. TLS authenticates all parties and encrypts all traffic. This does not prevent listening over the wire, but the attacker cannot read the traffic unless the encryption is broken. Additionally, by enabling SRTP voice, video and desktop sharing traffic will be encrypted.
How do I secure my voice traffic?
Are there Lync Server GPOs I can use to lock things down?
Yes, there is a communicator.adm file located in the %windir%\inf folder that you can leverage.
What are tips to secure my Lync Edge servers?
What do I need to exclude from my antivirus program running on my Lync Server 2010?

If you want to be more proactively informed on Lync updates there is a single web page called the ‘Updates Resource Center for Lync’ you can visit that lists all the Lync latest updates here or you can also run the Lync Best Practice Analyzer daily/weekly to ensure you have the latest hotfixes, patches, etc:
A common question for multi-datacenter deployments is how can we configure a DAG where failure will enable a DAG member locally vs. the other datacenter. This requires DAC mode. DAC or Datacenter Activation Mode is a property of the DAG that can be turned on or off and is disabled by default.
In Exchange 2010 SP1, DAC Mode has been extended to support two-member DAGs that each have a member in a separate datacenter. Bottom-line – you can now use DAC with DAG members in same or different AD Sites allowing the capability of using DAC with two or more members of a DAG.
A common deployment I have is with 4 members of DAG, 2 servers in each datacenter. FSW is in the primary Datacenter and will be quorum. Now Primary Datacenter has power outage. Manually, Exchange admin activates the secondary datacenter with an alternate file share witness.
When the power is restored in the primary site. When the two DAG members and witness server comes online, it has a quorum (majority) and will try to activate the databases. This will cause a “split brain syndrome” where both datacenters think that they are hosting the active databases.
DAC mode is used to avoid this and if enabled when the DAG members come online they will leverage Datacenter Activation Coordination Protocol (DACP) before trying to mount databases.
For more information on how this works check out the following Technet article. http://technet.microsoft.com/en-us/library/dd979790.aspx

Great write-up from EighTwOne (821) here.
As discussed with a lot of my customers Exchange UM no longer uses System Center (SCOM). Exchange 2010 with SP1 now has built-in reporting.
Call Data Records (CDR) are generated after each call. The server collects audio quality metrics with the same metrics that are used for the Monitoring server for Lync. Once the audio metrics are received they are stored in the e-discovery mailbox. They also have a lifetime of 90 days at which time they are automatically erased. This value can’t be changed but if you need them longer your can simply import them into a CSV file.
UM reporting features are done via EMC toolbox. If you are a tenant UM Admin you can also see them in ECP.
Call statistics provide stats about calls received or sent by UM Servers. In this case, to generate the CDRs, UM needs to read the CDR, and also need to calculate stats based on the period of time, type of call, dialplan, gateway, etc.
Call Stats are generated once per day and can be filtered by month or day for past 90 days.
More info on Call Statistics and individual call logs can be found here.
