How do I sync a calendar between my computer and iPad and iPhone?

Make sure that in the sync settings you don't have Outlook turned on or something. If that is on, and you don't actually have anything to sync in outlook (or don't even have it), then this can result in it sitting for a long time, if not forever. You might also try to check and make sure that a dialog didnt pop up and somehow get minimized to the dock or something as well. I had a similar issue with my ipod touch and all it ended up being was a stupid check box under the calendars sync settings.

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.

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

This solution pertains only to the one hour time difference people notice upon syncing to MS outlook.

In iPhone, there are two areas where you have an option to change your time settings.

1. When you go to 'settings', then to 'general', you can set up time and date, and also 12-24 hour format. Please note that changing the time here DOES NOT correct the problem, despite iPhone displaying correct date, time and time zone. Many people in this thread have stated that the problem persisted despite them setting appropriate time zone.

2. When you go to 'settings', then to 'mail, contacts and calendars' row (NOT the 'General' row) - you get an option to change your time zone at the very bottom of all the choices. You will see that wrong time zone is selected here - likely cause of the problem. Correct this choice and the one hour discrepancy between appointments in outlook and iPhone disappears.


Additional problem solutions - in the solution No. 2, if you set 'Time Zome Support' to 'ON', then all your appointments in the calendar will be displayed in the time zone of your HOME address. In other words, for example, if you are a person in central time zone, your appointments will be displayed ALWAYS in central time zone format - they will NOT change automatically when you travel from central time zone to eastern time zone. On the other hand, if you set the time zone support to 'OFF', then all your outlook appointment display times will change and adjust according to any time zone you travel to - This is often an inconvenience since most of us would like to remember our appointments as they were made in our home time zone, regardless of what time zone we traveled to.

Please note that the above solution pertains to only display of appoint times in outlook - This solution does NOT relate to the time displayed by iPhone and how that displayed time adjusts when you travel to different time zone away from your home time zone. This second issue is addressed below -

You can get your iPhone to display the current time in two ways -

1. Either always show the time in your home time zone, regardless of where you are (i.e., a person from Texas central time zone can set up to see the time always in central time, even if he/she travels to another time zone). This display setup is good for people who always think of time in their home time zone and then do mental conversions to reach at the local time zone time.

2. On the other hand, you can get iPhone to do this for you and change displayed clock time automatically to the local time zone that you have traveled to, away from your home time zone. Please note that enabling this capability in iPhone has no bearing on how the appointments are displayed in MS outlook.

Go to 'Settings'. Go to 'General' tab. then click on 'date and time'. Pick the 'set automatically' option to 'ON'. Now, the iPhone will automatically adjust displayed time to show the current time in which ever time zone you travel to.

If you set the 'set automatically' option to 'OFF', then you can select your home time zone. Then, the iPhone will always display time in your home city time zone and will NOT change even if you travel to a different time zone.

So, in summary, there are two places you need to adjust the time zones in iPhone - to do two separate tasks, first task of displaying appointments always in your home time zone upon syncing with outlook thereby avoiding the one hour skip; Second task of getting iPhone to display either your home time zone clock, or getting it to adjust current time to reflect the time in new time zone you travel to.

Hope this helps.
