Outlook meeting invites accepted on phone are an hour later than originally scheduled

Since DST started a couple of weeks ago, we have noticed an issue where an employee will send out meeting invites and if those invites are accepted from a phone, they will show up in Outlook an hour later than the scheduled time.  I've duplicated this issue from an iPhone and a Windows Phone 7 device.  The person sending the invites is using Outlook 2007.  When I go to accept the invite from either phone, there is a message in the email that says "The GMT offset above does not reflect daylight saving time adjustments."  If I accept the invitation in Outlook, the meeting is scheduled with the correct time.  This is only happening from users who have Outlook 2007.

Did you verify if you have the latest office and windows updates and service packs?  You will need to have them recreate the meetings if updates were not installed.

PC may have all the latest updates, but this symptom really appears as if some are missing the DST Updates itself

http://support.microsoft.com/gp/cp_dst

Need to check that all PCs have the latest DST update applied

There is no harm in applying it again, you would only get a msg saying that its already been applied

You will also need to make sure the DST update is installed on all the servers as well.

The Iphone Device Should be automatically updated for DST, as this runs via a much larger Cellular System which is for the most part, always up to date.

If you phone is not updating may need to check the following

however, i doubt this is the case

It sounds like the settings on the phone is the issue.

On the iphone, go to settings > general > date / time can you toggle the time zone support on and off and see which one makes a difference.

I would have you check Outlook > calendar options > and make sure allow changes for DST is checked as well (but it seems to work for you already).
