~~~~ Sponsor: C2C Email Content and PST Discovery ~~~~

Active Folders Content Manager is essential for every Exchange administrator's toolbox!

* Acts on PSTs (local and central), mailboxes and public folders.

* CLEANS viruses from Exchange on the fly for a layered defense.

* LOCATES and REMOVES non-business related attachments.

* FREES-UP redundant storage space.

* DISCOVERS email by multiple criteria.

Running automated, granular rules-based processes on a regular basis can save you essential time and resources and keep your organization's email legal. Content Manager runs in the background so email services stay live, even when a critical virus hits the system.

Content Manager now acts on all local and central PST files as well as mailboxes and public folders. One product does it all.



==== 1. Commentary: Exchange's Performance Testing Tools ==== by Paul Robichaux, News Editor, [email protected]

Albert Einstein reportedly had a sign on his wall that read "Not everything that counts can be counted, and not everything that can be counted counts." The second half of this admirable sentiment isn't true when it comes to Exchange Server design and deployment. Typically, the goal when designing a server is to provide a certain level of service quality or performance (as expressed by a service level agreement--SLA), so anything that we can count to help us objectively measure the level of server performance can be useful.

Microsoft's Exchange Server 2003 Tools and Updates site includes three tools that can help measure server performance, tuning, and scalability. You can use these tools together to test various aspects of your Exchange server design.

The first tool is Load Simulator (LoadSim) 2003. Good old LoadSim has been around for a while, but the most recent version implements the relatively new Messaging API (MAPI) Messaging Benchmark 3 (MMB-3) and can simulate loads generated by Outlook 2003 operating in Exchange cached mode. MMB provides a standardized way to test server performance by making a fixed set of MAPI requests against the server. By tuning the number and type of requests, you can make LoadSim approximate various kinds of messaging loads, from heavy to light. LoadSim simulates only MAPI clients, though; if you're using Internet-protocol clients, you'll need another tool.

That tool is Exchange Stress and Performance (ESP) 2003 (sometimes known as Medusa). What LoadSim does for MAPI clients, ESP does for IMAP, POP, and Outlook Web Access (OWA) clients. ESP gives you a range of configuration options to control which specific protocols to test and what kind of load to present to your server.

The third tool is Jetstress. Whereas LoadSim and ESP simulate client behavior, Jetstress stresses the stuffing out of your disk subsystem by making I/O requests that follow the patterns typical of production Exchange servers. Of course, you still need to use Performance Monitor or a similar tool to watch the parameters you're interested in (e.g., average disk queue length) and see what effect Jetstress is actually having.

ESP and Jetstress work on Exchange Server 2003 and Exchange 2000 Server; LoadSim works on these systems and on Exchange Server 5.5. Each tool comes with documentation that explains how to use it and what it can measure (for example, you probably won't want to use Jetstress to measure disk performance on a test server whose hardware is significantly different from your production equipment's hardware).

==== 3. Instant Poll ====

Results of Previous Poll: Outlook 2003

The voting has ended in the Windows & .NET Magazine Exchange & Outlook Web page's nonscientific Instant Poll for the question "What are your plans for Outlook 2003?" Here are the results from the 311 votes:

- 21% We plan to deploy it immediately

- 23% We'll deploy it within 6 months

- 22% We'll deploy it within 1 year

- 9% We'll deploy it within 2-3 years

- 24% We have no plans to deploy Outlook 2003

(Deviations from 100% are due to rounding.)

New Instant Poll: Exchange Clusters

The next Exchange Instant Poll question is "What's your approach to Exchange Server clusters?" Go to the Exchange & Outlook Web page and submit your vote for a) We run Exchange Server 5.5 clusters, b) We run Exchange 2000 Server clusters, c) We run Exchange Server 2003 clusters, d) We don't cluster Exchange but would like to do so, or e) We don't cluster Exchange and see no reason to do so.

Outlook Tip: Determining When Appointments Were Made by Sue Mosher, [email protected]

Q: I'm trying to determine when a particular Outlook calendar entry was made. I know that I can view the Modified date on an appointment's Properties dialog box, but how can I find out when an appointment first appeared?

A: You must switch to a table view, such as Active Appointments. Right-click the column headings and choose Field Chooser. From the Date/Time fields list, drag the Created field to the column headings to add that property to the view.

See the Windows & .NET Magazine Exchange & Outlook Web page for more great tips from Sue Mosher.
