Sync Problem My iPAQ syncs everything a day backwards. If I post and appointment on my microsoft outlook on my laptop and sync it to the iPAQ it shows up the day before the appointment. Example: Appointment scheduled for Tue April 1 on Laptop appears on Mon March 31st on iPAQ. Got any suggestions?

Make sure time-zone is the same for both iPhone and the computer.

On iPhone setting > Mail,Contacts,Calendars setting > Time Zone Support, make sure you are choosing the city where you are in.

Otherwise, make sure you have updated the iTunes to 7.5 or later.

Update to iTunes 7.5 or later to resolve this issue. If you're not able to update, continue reading for other options to resolve the issue.
Each Outlook calendar event has an internal property known as "Message Class." When some Outlook plug-ins are installed (such as Live Search Maps), the setting for the Message Class property can change from its default of "IPM.Appointment" to something else. iPhone and iPod touch are only able sync calendar events with the Message Class set to "IPM.Appointment," therefore any calendar events created after installing certain Outlook plugins may no longer sync.
To verify this, examine the property of the Calendar event items for MS Outlook and see if the Message Class shows something other than "IPM.Appointment" in any of the calendar events. To view the Message Class property for your Outlook Calendar events, add the Message Class field as one of the columns in the Current View using these steps:

1. Open Outlook Calendar on the computer.
2. Choose View > Current View > Events.
3. For Windows Vista, choose View > Current View > Customize Current View.
   For Windows XP, choose View > Arrange By > Current View > Customize Current View.
4. Click the Fields button and choose All Appointment fields from the pop-up menu in the "Select available fields from" section.
5. In the "Available Fields" column, select "Message Class" and click the Add button.
6. Click OK.
7. Click OK.

Now verify that all your calendar events are showing "IPM.Appointment" for the Message Class column. If you have calendar events showing a different value other than "IPM.Appointment" you will need to perform the following steps to fix the issue.

1. Uninstall any Outlook plugins such as Live Search Maps or other plugins which change the default Message Class "IPM.Appointment" to some other value. Once the plugins have been removed, verify if those calendar events revert back to the Message Class of "IPM.Appointment" so that you can sync the calendar data to iPhone/iPod touch. If you are able to sync, try adding the plugins back one at a time and verify that you are still able to sync.
2. If removing the Outlook plugins does not change the Message Class value for the calendar events, manually change the Message Class value of those calendar events to "IPM.Appointment." For more information on Message Class and how to change the Message Class fields/value, refer to Microsoft's KB article 201087 How to update existing items in an Outlook folder to use a new custom form

Good luck!

I've decided to get a smartphone with Windows Mobile 6.1, so this issue has been "solved"

you are now using outlook 2003 , probably cache , this means all the email is on your laptop. when you sync it will sync all the email (thousands). initialise your ppc (back to factory default). set up the sync via usb cable. then sync via bluetooth . then you are fully sync. now setup an auto backup of your email data (daily). if after some time , you have sync problem again , initialise the ppc, restore from backup and you are back to sync (last full backup). try this , you will never need to do it all again.

just install itunes and you can sync calendar and contact to your iphone. You cannot sync the notes and tasks but. I have just bought an iphone and before I was using an HP ipaq like you. Everything is synced except for the notes and tasks. You cannot even see any word or excel files you had on your ipaq. Cheers

You need active sync

Problem was solved by HP folks! talkinglens!

Usually the simplest solution with Microsoft software such as active-sync is to uninstall it and install it again from scratch. When you reinstall it will ask you what programs you want to sync with, your old PIM software has been lowered in priority in favour of Outlook because MS think everyone should want to use it, so it's often easier to start using Outlook as your main PIM.

Hi, This could be due to a few issues, try these soloutions in order below: 1) If you have a jacket connected to the ipaq it could be preventing the ipaq from locating correctly on the connector. Remove jacket and try insering again. 2) Check that active sync is set up to detect the device on the usb port. The cradle for the ipaq may have a serial and usb connector. Ensure that just the usb connector is attached to your laptop. Try connecting again. 3) You may need to uninstall the USB cradle if it was connected before installing active sync. Try the following steps if this was the case: a) unplug the USB cradle b) uninstall active sync c)Click start then click control pannel then click system. Then click on the hardware tab. Look for the device under USB, right click on the device and then select uninstall. d) restart the laptop e) Install active sync f) ONLY after active sync has installed you can now plug the cradle back into the usb socket. g) Now connect the ipaq, it should now detect it.

Reinstalled Active Sync and Outlook.

Try the following.... Open Active sync on your PC. Double Click on Calendar. Change the settings such that it syncs only 0 past and 0 future appointments. SYNC (this will clear all calendar items on the IPAQ) Now go back in to those Calendar settings, and set it back to the default which is 2 past weeks and All Future appointments. SYNC (this will now reload all appointments into your Ipaq)
