To do this we need to take a look at the size of our *-BINPATCH-.LZX files Essentially what we are trying to do with this value is determine how much bandwidth we need on a daily basis to keep Outlook’s OAB up to date.
%GAL Changes per Day is a little more complex.

Offline Address Book size is simply the size of your *-DATA-.LZX file. The bandwidth calc asks for two pieces of information about your OAB file: So which bits do I need for the Exchange Client Network Bandwidth Calculator? You can see from this that my lab has had 4 generations of the OAB.

If there have been no changes since the last build, there will be no iteration of the sequence number and the clients will not download any patches. The number is iterated each time the OAB is regenerated. These files are language files used by the client to generate a language specific OAB. Clients that are connected every day will download the latest BINPATCH file every day. These files represent delta changes since the last OAB generation. It contains all of the raw binary data within the OAB

If you trigger a full OAB download this file is always requested. Clients will download this XML file to determine how far out of date they are and which files they need to get up to date. Let’s take a look at the files we have… File Now, this is the interesting question! So, we know where our OAB files are, but which files are important? What are all of these files inside my Offline Address Book Folder then? This folder is where your OAB files are stored if we take a look inside the folder, we can see the files that are used by clients to generate the OAB can be found….
In my lab I only have a single OAB file, so it’s pretty easy.
Inside this folder we need to look for a folder with the name that matches our OAB GUID returned earlier. To find the actual files, we need to take a look at the server that is generating the OAB file on that server we need to look in the following folder Ĭ:\Program Files\Microsoft\Exchange Server\V14\ExchangeOAB\

I am hoping that everyone reading this is using OABv4 – if you’re not then it’s probably time you looked at how to upgrade since there are many benefits from OABv4 including additional stability and much better bandwidth usage. Note: Before we dive in it is important to note here that I am concentrating on OABv4 – this was introduced with Exchange Server 2003 SP2 and Outlook 2003 SP2 (that was a long time ago!). I decided that I would start this post to explain what the OABv4 files are, where to find them and how to determine the size of your OABv4 file J This was tricky since I needed to know the size of the OAB so that we could predict how it might affect the network bandwidth requirements for that customer. One of the things that I noticed while creating and validating the Exchange Client Network Bandwidth Calculator was that many organizations did not know much about their OAB size or placement. When we perform network bandwidth planning for Exchange deployments we always ask “what is the size of your OAB?” This is important since if you have a large OAB file it can severely affect the amount of network bandwidth that you require.
