Office Communicator 2005

I downloaded the latest build of Office Communicator 2005 (Istanbul) to play with last week, and Im seriously impressed with the functionality of the new client.  you know, its the little things that make such a difference.  Like the fact that my status automatically turns to busy – (a blue no entry sign) when my Outlook calendar is marked with a meeting, and the fact that I can set a note on the client (It says I’m sitting in my conservatory right now J). and there’s a big red do not disturb no entry sign for when I really don’t want to be bothered with things. 

I’m not even telling you stuff that’s not available to you.  You can sign up for the beta and test too. You do need to be running Live communications Server though.  Don’t forget to read the instructions on the web page

There is also lots of information on the RTC launch including a webcast from Bill…

 For those that missed the live broadcast, you can now view an on-demand version of the webcast (1 hr. 6 min): http://web.archive.org/web/20051210052427/http://www.microsoft.com/billgates/speeches.asp56 Kbps | 100 Kbps | 300 Kbps

Message size limits in Exchange 2003

Did you know that there are four separate places where you can set message size limits in Exchange?  If any one of them has a lower size limit than another, then that restriction applies.  So you can set size limits at the following levels:

  • Globally
  • At the connector.  You can configure different message sizes for each connector.
  • at the SMTP Virtual server
  • and at the individal user level

There’s a good example in the KB article which explains how it works and helps to troubleshoot issues and stops you going round and round in circles.  But be aware of the conditions that can prevent message delivery:

In this example, the following size limits have been configured:

The global setting is set to 5 MB.
The Exchange SMTP connector is set to 3 MB.
The SMTP virtual server is set to 4 MB.
The user mailbox setting is set to 2 MB.

Because of these settings, users in the Exchange 2000 or Exchange 2003 organization can send and receive messages that are a maximum of 5 MB. Users can send messages through the connector that are a maximum of 3 MB. All mail that passes through the SMTP Virtual Server (sending or receiving) is limited to 4MB. The individual user, whose mailbox setting is 2 MB, is also limited to sending and receiving messages that are a maximum of 2 MB.

MOM management pack for ExBPA

Oooh! this is interesting.  Whenever we talk about the Exchange Best Practices analyser, we get asked where it fits in with MOM and MOM’s management pack and guide for Exchange.  Well here’s the thing that effectively connects MOM and the ExBPA.  You can even now deploy ExBPA using MOM.  Download it here

The ExBPA Management Pack works in conjunction with the ExBPA tool to provide administrators with recommendations on how to improve performance, scalability and availability of Exchange server topologies.

The Microsoft Exchange Server Best Practices Analyzer (ExBPA) Management Pack can be used to deploy the ExBPA tool on computers running Microsoft Exchange Server 5.5, Exchange 2000 Server and Exchange Server 2003. Using a timed event, the tool will run automatically on each server and write any identified performance, scalability and availability issues to the Windows NT Event Log. The ExBPA Management Pack will interpret these events and generate the appropriate alerts on the MOM Management Console.

The ExBPA Management Pack works in tandem with the ExBPA tool:

o        Identification of Exchange server configuration issues which could result in poor performance, scalability and unplanned downtime

o        Automated analysis and root cause identification

o        Support for third-party software and hardware

o        Self-updating database and help content

o        Links to over 500 articles on the Web

o        Works with Exchange Server 2003, Exchange 2000 Server and Exchange Server 5.5 (in mixed mode topologies)
