recurring appoints in outlook 2007 appears as 25 hour events

have you applied DST patch? http://support.microsoft.com/kb/955839/en-us
what is your OS?

Currently running Windows XP, Not sure if DST patch has been applied.

you can check in add/remove programs, click show updates. View the KB# installed and compare against the download in the link i provided. If not install and let em know if it works. I have seen a number of cases like yours resolved from DST patch.

Have you tried going into the Appointment Recurrence settings and changing the duration of the event from 25 hours back to 1 hour?
I know this has happened to me once or twice without me realizing it right away when I change dates for an event; you should be able to adjust the duration to as long or short as you need it, though it may also be necessary to adjust the start and/or end date to allow for the shorter duration.

How do you get to that Window boardgirl148?

diverseit:

The patch has been installed

Click the appointment to open it. Choose edit the series. On the Options ribbon click Recurrence. THis will open the Recurrance dialogue box. Under APointment time change Duration to 1 day.
See the attchment.

are you using a windows phone to sync? if so, you will need to apply its DST patch as well (http://www.microsoft.com/windowsmobile/en-us/downloads/microsoft/daylight-savings-update.mspx)
Here is the PST update for Outlook 2k3 and 2k7. http://support.microsoft.com/kb/931667
These patches will prevent this from happening again. Also running the Outlook patch should correct any items that fall into this error.

Yep, diverseit has pointed you to the right place.
Except, if it is an existing meeting, it will look slightly different.  Open the series of meetings, then choose the smaller "Recurrence" button.

Hope that helps.

There's a Blackberry, but that's syncing through the BES, and the PC is patched up to date

Ok then i would only update the Outlook for sure! The patch should go through each item to make sure it is correct and if its not it will record the results. then it will prompt you to leave the erroneous items or to automatically correct them.

The Patch was already installed. Didn't fix the problem

A few clarifying questions:
- Is this affecting all of your appointments and meetings, or just some of them?
- Did this happen all of a sudden to existing appointments/meetings that were previously ok, or is it only happening to new ones that are added?

after you install the OS patch you need to run this again http://www.microsoft.com/downloads/details.aspx?FamilyID=e343a233-b9c8-4652-9dd8-ae0f1af62568&displaylang=en
it should correct any problems.
what happens when you try to change the recurring duration from 25 hours to 1 day?

It's affecting all the user appoints and it just started all of a sudden. All the appointments are now coming out as 25 hour appoints. The user is now changing them to 0 hours, but i still need to change the default.

so i understand you correctly EVERY appointment no matter how it is generated or created is set to 25 hrs regarless of the type e.g. new appt., meeting request, new recurring appt, etc.??
So if you click and make a new non-recurring appt. it defaults to 25hrs?
FYI: you should have offered 500 points for this...
Verify work week hours: go to Tools >> Options >> under Clanedar section click Claendar Options... >> under Calendar work week section >> verify start time and end time are normall...not 12a 12a.

Can you attach a screen shot for an example?
