Actually, only recurring meetings are stamped with a time zone.  Single 
Instance meeting aren't. That's why the tool needs to be run.  BTW and that's 
only Exchange 2003 and earlier, Exchange 2007 DOES stamp every meeting with 
time zone information.

The tool basically moves all single instance meetings one hour during that 3 
week period when the computer wouldn't have known that DST started.  These are 
for previously scheduled meetings.

One thing to keep in mind, if you patch the workstation OS, you want to run the 
calendar tool ASAP.  As soon as you patch the OS, the computer till know about 
DST and schedule the meetings correctly.  When you then run the tool on these 
correctly scheduled meetings, it will still move them by an hour.

  Per the article, yes, you have to. But if you read the article that says how 
Outlook stamps Calendar time, it makes it a little confusing as to why we need 
to run this tool. All calendar items are stamped with GMT. Then, based on the 
client Time zone settings, the Calendar item's time should be converted to the 
local time. So if the client and server are patched, it should be sufficient to 
convert the GMT stamps into local time. I am trying to research more into this.

  Is it necessary doing this if both server and clients are fully patched with 
wsus?
