IMPORTANT If you want to add a Google Calendar account on your smartphone, make sure your Gmail account includes Google Calendar before you add your Google account on your smartphone. By default, Gmail accounts do not automatically include Google Calendar. If you don't already have a Gmail account, go to mail.google.com and create one. To add Google Calendar to your Gmail account, go to google.com/calendar and log in using your Gmail account name and password. When prompted, add Google Calendar to your account.
•Verify the default calendar account. When a new calendar event is created on the smartphone, it syncs with the default account (see Customise Calendar).
•Manually sync Calendar (see Manually synchronise Calendar with your online accounts).
NOTE You should see a notification at the bottom of your screen when the account starts to sync. You may have to wait up to 30 minutes after a sync operation starts for your data to appear if the data is located in an online account.
•Delete the account on the smartphone and then
Some of my calendar information is missing
•If the missing calendar information is from an Exchange account, make sure the email account is set up as an Exchange account, not a POP or IMAP account. An Exchange account that is set up as a POP or IMAP account cannot sync calendar information (see Change account login settings).
•Verify that your calendar information is correct in your online account.
•Verify that the calendar information is correct on the smartphone.
•Note the following and determine if the missing information is actually available for syncing:
•Google accounts sync events one month back and two months forward.
•Yahoo! accounts sync events one month back and three months forward.
•Exchange accounts sync events two weeks back and unlimited forward.
•Sync your Calendar accounts (see Manually synchronise Calendar with your online accounts).
•Set the Default Account (see Customise Calendar).
My calendar data is in the wrong field
•If your incorrect calendar data is being synced from an online account, update the calendar information in your online account. If your incorrect calendar data is being backed up with your HP webOS Account, update your calendar information on your smartphone.
•Manually synchronise Calendar (see Manually synchronise Calendar with your online accounts).
•Open Date & Time 
and check whether the online account and the smartphone are using the same time zone setting. If not, change the time zone either on the smartphone or in the online account so that the time zones match.
I have duplicate calendar events
•If the events are from an online account, delete the account from your smartphone (see Use the Accounts application to edit or delete an online account), log in to the account on your computer and delete any duplicate data and then add the account to your smartphone again (see Use the Accounts application to set up an online account).
•If the events are in your HP webOS Account, turn off Backup (see Erase HP webOS Account information from the server), delete the duplicate calendar events on your smartphone (see Delete an event) and then turn on Backup again (see Manually back up information to your HP webOS Account).
Calendar notifications are not working
•Make sure that the ringer switch is on and that the ringer switch volume is set to at least 50% (see Set ringer switch settings).
