Microsoft Lync 2013 TechEd NA 2013 online sessions

Below you can find links to online sessions from TechEd 2013 North America.
All sessions are about Microsoft Lync Server 2013.


Microsoft Lync Hybrid Scenarios

Abi Maggu – This session examines the use of Microsoft Lync Online in a hybrid environment for user access, now possible with the release of Lync 2013 to Microsoft Office 365. For existing deployments, using Lync infrastructure already deployed, customers can easily expand their environment into Office 365. New deployments can also benefit by decreasing the on-premises Lync footprint and hosting users online. Benefits of using Lync Online in a hybrid configuration include being able to leverage global infrastructure to provide ease of access, a reduced on-premises server footprint, being able to consume cloud services at your pace, additional capacity on demand, and hosting users in highly available and secured datacenters. Lync Online through hybrid provides both a model for easy expansion and a model for cloud services at your own terms.

Microsoft Exchange Server 2013 Managed Availability


Ross Smith

In this session, learn about managed availability. With managed availability, internal monitoring and recovery-oriented features are tightly integrated to help prevent failures, proactively restore services, initiate server failovers automatically, or alert administrators to take action. The focus is on monitoring and managing the end user experience rather than just server and component uptime to help keep the service continuously available.

Exchange 2013 CU2 – mailbox databases limit changes

Administrators of Exchange 2010 who have more than 50 databases can now be happy.

Exchange 2013 enterprise has limit of 50 databases per server, but not with CU2 !!!!

Exchange Team has released that many of us have Exchange 2010 environments with more than 50 databases. And during migration to Exchange 2013 enterprise it could be a problem to decrease number of mailbox databases to 50 per server.

So when you install CU2 for Microsoft Exchange 2013, mailbox databases limit for enterprise version will be increased to 100.

CU2 is expected later this summer.

CU2 won’t change number of databases pers server for standard edition, and it will be 5 per server.

Exchange 2010 Administrator Audit Log – configuration


If your Exchange organization has more than one administrators, and sometimes you need to know who did what, then you should use Exchange Administrator Audit Log.

When you enable Administrator Audit Log it will help you to keep a track of the changes made to any Exchange configuration like:

creating new mailbox, changing receive connectors, transport rules etc.


Those information are quite important during troubleshooting your Exchange environment.

In Microsoft Exchange 2010 RTM, Administrator Audit Log logged all operations to mailbox. When you enable audit log then you need to use parameter AdminAuditLogMailbox to specify mailbox to store all audit logs.

But with SP1 for Exchange 2010 you don’t need to use mailbox anymore.

Now all logs are stored in a hidden, dedicated arbitration mailbox.


To check if Administrator Audit Log is enabled we should use following command:

Get-AdminAuditLogConfig | FL


we will receive information about audit settings like below:
