Live Meeting-to-Lync Transition

Transitioning from the Microsoft Office Live Meeting Service (LMS) to Microsoft Lync enables your organization to streamline all of your collaboration needs into one application. Lync provides intuitive communications capabilities with presence, instant messaging, audio/video calling, and a rich online meeting experience with PC-audio, video, and web conferencing.

Transitioning includes two related efforts: 
(1) ramping down your LMS usage and
(2) rolling out Lync to your organization. To help ensure positive end-user change experience and smooth transition, it is critical you understand your current LMS environment prior to implementing your transition to Lync.

Exchange 2013-Offline Address Book

Outlook cached mode
·         Cached mode is the new default configuration for Outlook.
·         It provides an experience that is similar to the offline configuration in earlier versions of Outlook.
·         When you are running in cached mode, your Exchange mailbox is synchronized to a local file (an .ost file), and the offline address list from your Exchange computer is synchronized to a collection of files (.oab files) on your client computer. Therefore, network communication between Outlook and Exchange is significantly reduced. 

 Why  offline address book is important
·         The offline address book contains a set of all the properties of a user that Outlook requires.
·         With an offline address book, Outlook does not have to connect to the global catalog to resolve names.
Difference  between  offline address book and  the global address list
·         The offline address book is a snapshot of the Active Directory directory service information that is available in the global address list.
·         some information is available in the global address list that is not available in the offline address book.
·         The offline address book does not contain some  items that are available in the global address list like custome properties , Organization hierarchy information and  Group membership information
·         If you are in cached mode and if you are working online , Outlook uses both the offline address book and the global address list to provide a complete listing of user information.
·         If you are in cached mode and if your connection status show Disconnected ,  you can see only the information that is available in the offline address book.

 New offline address book features
·         Exchange 2003 and later supports a Unicode offline address book.
·         The Unicode version in exchange 2013 is also known as Version 4 similer to the exchange 2010.
·         Has a filtering mechanism in place that makes sure that only those certificates that are used by Outlook for public key infrastructure (PKI) will be present in the offline address book which significantly reduces the size of the offline address book from servers.

Offline address book updates
·         If left constantly running, Outlook in cached mode automatically updates the offline address book on the client every 24 hours.
·         Different people will receive updates at different, random times.
·         By default, the Exchange computer generates the offline address book files every morning at 05:00.
·         If outlook taking long time to download the OAB, It might be the issue of Active directory replication or hard disk slow performance.

Offline address book sizes
·         Offline address book sizes can vary from 3 MB to 700 MB.
·          Size depends upon  usage of certificates in a company, number of users , distribution groups   in Active Directory. Full offline address book size is approximately 1 MB per 1,000 users.

Exchange User Monitor tracing via the command line

For troubleshooting Exchange user performance related issues or to help plan your design for Exchange, Exchange User Monitor (Exmon) is a great utility to have in your tool bag and contains a wealth of knowledge on your current user activities.
Exmon tracing uses the ETW (Event Tracing for Windows) facility of Windows to send internal application event data to .etl files for later analysis.

Before enabling ExMon tracing, the following registry keys must be added to the registry to allow Exmon to collect data in the ETL file.
To enable tracing on any given server, there is essentially 2 methods that can be used to create and start/stop Exmon tracing.
2. Create a directory called Tracing (ex. C:\tracing)
3. Copy tracelog.exe to this directory from the default install location of c:\program files\Resource Kit.
4. Create a start_tracing.cmd file and add the following information to the file. Save this to the location created in Step 2.
tracelog.exe -start Exmon_Trace -f c:\Tracing\Exmon_trace.etl -seq 3500 -guid control.guid
5. Create a stop_tracing.cmd file and add the following information to the file. Save this to the location created in Step 2.
tracelog.exe -stop Exmon_Trace
6. Create a control.guid file and then add the appropriate GUID for Exmon tracing. Note: This GUID should be the only piece of information in this file. Save this to the location created in Step 2.
7. To verify if these batch files work successfully, run start_tracing.cmd and then run tracelog -l and look for an entry call Exmon_Trace. If this is found in the list, then the tracing has been enabled as shown below.
