And here you were thinking that your Mac would be immune to the DST problems that seem to be plaguing the rest of the US. Well, not necessarily. Turns out that Microsoft has included updates in Office Update 11.3.3 for Entourage that handles issues related to calendar items and the new DST rules. And if you’re only using Entourage 2004 for POP3 or IMAP accounts, you’re probably going to be OK. But only if you install Update 11.3.3 (at least according to KB924606).

But, if you’re using Entourage 2004 to connect to an Exchange server, your calendar may just get a little funky for a little while. According to a blog post from the MS Higher Education West group, if the Exchange server has not been updated with the patches to fix the DST issue. Where can I learn about these updates, you may be asking? Well, this Microsoft page has information, and http://www.dstpatch.com/ also has update information.

Bottom line, the patch for Exchange is out, but not necessarily universally installed. The Entourage patch is out, as is the OS update from Apple that allows the core Mac OS to handle the new DST laws. But the Outlook patch is not yet available, so expect that until all three players are updated in a particular location there will be some discrepancies about meetings that are scheduled after March 11, 2007.

My Mac recommendation: go ahead and update to 11.3.3 for Office for the Mac, but be aware of possible DST meeting hiccups until everyone else gets updates.
