Error Code 1008

For more information about this message, please see our Help Center article Google Calendar Sync: Error 1008.

 

I'm receiving this error: "Some of your Outlook appointments could not be loaded. Sync is interrupted in order to prevent potential data loss."

 

This issue can be resolved by taking manual action on these events. To do so, please follow the steps below:

1. Open your calendar in Microsoft Outlook.
2. Select "View by Category." (Main Menu > View > Arrange By > Current View > By Category)
3. You'll see a list of events (if the events are collapsed in categories, you can expand them by clicking the "+" sign). Using the icons to the left of each event, find events that have a "warning" icon (i.e. crossing swords), events that don't have a start date or end date, or events which have an end date before the start date.
4. Double-click on each problematic event to resolve the problem or delete the problematic events.

Google Calendar Sync fails with an error message or Outlook crashes.

Google Calendar Sync reports "You seem to have outdated time zone information. Please run Windows Update."

This error message will appear when your Microsoft Windows Operating System doesn't have the latest time zone updates. Normally these updates are auto-installed as part of a Windows Update.

If the updates above don't resolve your issue, you may want to try manually restoring missing time zone definitions by following the instructions here.


I'm asked "Do you want to delete ## events" when syncing.

This message will display if you've recently deleted more than 10 events from one of your calendar clients (Google Calendar or Outlook) and then initiate sync. After initiating sync, any deleted appointments will also be removed from your other calendar client. To avoid confusion or accidental deletion, we've added this message to warn people that running Google Calendar Sync will populate recent deletions to both calendars.

Other Issues

I'm using Live Search Maps Add-in for Outlook and my events aren't syncing.

Thanks to mdivrx's findings here, we've learned that Live Search Maps Add-in for Outlook prevents Google Calendar Sync from working successfully. We're looking into this behavior further and hope to be compatible with this set-up soon.

 

 

Can I sync events from secondary calendars?

No, it's not possible to sync events on secondary calendars at this time. Google Calendar Sync will sync only events from your primary Google Calendar (first one in your list) and your default Microsoft Outlook calendar. If you've scheduled events on a secondary calendar in Google Calendar that you'd like to sync with your Microsoft Outlook Calendar, you can either move the event to your primary calendar or export your entire secondary calendar and import the events to your primary calendar.

Compatibility

Google Calendar Sync isn't working with Windows XP 64-bit Edition.
 

Please be informed that Windows XP 64-bit Edition isn’t compatible with Google Calendar Sync at this time.

The team here is definitely aware of the strong desire to use this feature and we're keeping track of all reports and requests as we work to improve Google Calendar Sync.

I'm currently using a third-party sync application to sync between Microsoft Outlook and Google Calendar. Can I continue to use this third-party application AND Google Calendar Sync?

We understand that many people like to stay connected with various calendar applications. Unfortunately, it's not recommended to use Google Calendar Sync when using third-party sync applications that sync between Microsoft Outlook and Google Calendar. Please be aware that doing so may result in duplicated events or deleted data.

If you're currently using a product that syncs between Outlook and Google Calendar, please do the following before installing Google Calendar Sync:

1. Disable or uninstall the third-party sync software.
2. Determine which calendar (Outlook or Google Calendar) contains the majority of your reference information (i.e. event properties, guests, and reminder information). This is your "main" calendar.
3. Once you've designated your main calendar, clear the data from your other calendar. (For example, if Google Calendar was your "main" calendar, delete the event data from your Outlook calendar.)
4. Install and run Google Calendar Sync. Choose "1-way sync" from your "main" calendar to the other (you'll be able to change sync direction later).
5. Perform synchronization. Your events will appear in both Google Calendar and Outlook once again.

Please keep in mind that you can create a back-up copy of your Google Calendar events by exporting your calendar data. For detailed steps, see Export your calendar data.

Does Google Calendar Sync work with Google Apps?

Yes, you just need to specify your full email address in the Google Calendar Sync Settings window.
