HowTo-Outlook

If you’re running Outlook 2010 Beta (build 4536) and suffering from the message size bug, you can now fix it with a special update for the Office 2010 Beta.

The Outlook Team has released an update for both the 32-bit and the 64-bit version of Office 2010 Beta.

Update Rollup 2 for Exchange 2007 SP2 has been released.
For a list of changes that are included in this update rollup, see KB972076.

It’s also offered via Microsoft Update on the Exchange server itself.

The Internet Explorer security leak, for which a patch is now available, could also affect your Outlook security. This is only the case when you are working with Outlook 2003 and previous and have your Internet Security Zone for Outlook set to the Internet Zone. Outlook 2007 and Outlook 2010 Beta are not affected.

Currently there are no known exploits of this security leak that work via Outlook 2003 or previous. However, in order to protect yourself, make sure you have your Security Zone for Outlook 2003 or previous set to “Restricted sites”. This zone is also the secure default and the recommended setting. You can verify this setting by going to;
Tools-> Options…-> tab Security

This exploit could also surface via other parts of Windows (such as via Gadgets, Outlook Express, Windows (Live) Mail and the Help system (chm-files)) since they all rely on Internet Explorer components. So even when you are not using Internet Explorer as your Internet browser, it is still highly recommended to install this update as soon as possible.

You can get this update via Windows Update as well.

The Outlook Team has put out a warning about large message sizes when sending out a message with Outlook 2010. While working with a Beta version of software could always lead to unexpected results, this bug can also affect the recipient of the message.

The issue is related to using bullet lists. When you use bullet lists in your message, the CSS of the message (which controls the formatting of the message) does not get properly truncated and a small message could become quite big. This could even result in that the message may no longer be displayed correctly at the recipients end.

The current fix is to simply restart Outlook 2010 Beta (at least once every day). This issue will be fixed of course once Outlook 2010 gets released.
