Missing invitations or updates for events are usually caused by one of the following:

• Make sure that your notification settings are correctly set to receive invitations. See Customize your notifications to learn more.

• Check that your spam filter isn't blocking or redirecting mail from Google Calendar. If invitations are being marked as spam in Gmail, select the invitation messages in your Spam folder and click the Not Spam button.

• The event might have been intentionally added to your calendar without notification. This happens when the creator of the event clicks Don't send when saving the event.

Make sure that your notification settings are correctly set to receive invitations. To access these settings, find your calendar in the My calendars section on the left, then click the drop-down arrow and select Notifications.

See Customize your notifications to learn more.

Check these possible causes for missing email reminders:

• Check that your spam filter isn't blocking or redirecting mail from Google Calendar. If invitations are being marked as spam in Gmail, select the invitation messages in your Spam folder and click the Not Spam button.

• Make sure that the time zone is set correctly on the Calendar Settings page and on your computer. See Change the time zone for help setting your Calendar's time zone. Contact your system administrator if you need help setting the time zone on your computer.

• If you're using a client to sync your mail (such as Microsoft Outlook or Mozilla Thunderbird), and if it only checks for email every few minutes, email reminders might arrive late.

Make sure Google Calendar is open. You must be signed into Calendar in order to see pop-up notifications.

Check these possible causes for missing SMS reminders:

• Make sure to specify the correct mobile number on the Mobile Setup settings page. To access the Mobile Setup settings page:

  1. Click the gear icon at the top of any Google Calendar page and select Calendar settings.
  2. Select the Mobile Setup tab.

• Make sure your mobile provider is a supported provider.

• Your mobile provider's traffic might be high, resulting in delayed reminders.

• You might have reached the Calendar limit for daily SMS notifications. If that's the case, SMS notifications will resume again within 24 hours.

If an event has disappeared from your calendar, try these possible fixes:

• If an event has disappeared from your calendar, it's possible that the owner of the event (or another user with modification rights) has deleted the event without notifying the attendees. Check with the event owner or other attendees to make sure the event is still happening.

• If you're syncing your calendar with a mobile device or another calendar client application, it's possible that the client application deleted the event. Sometimes client applications delete events in order to save space. Make sure to configure the settings on the client application to not automatically delete events.

• If you're syncing with a Blackberry, if you accept the invitation and then delete the event invitation mail on the Blackberry device, the event is also deleted. Make sure not to delete calendar invitations on the Blackberry.

If your primary calendar has disappeared, make sure that it isn't hidden. Look at the left side of the page under My calendars. If your calendar name doesn't have a colored bar running through it, the calendar is hidden. Click the calendar name to display it again.

If you're receiving an error message like ‘Oops’ or ‘Loading,’ try the following:

• Refresh the browser several times
• Clear your browser's cache and cookies
• Sign in and out of your Google Apps account

If a secondary or shared calendar has disappeared, try these possible fixes:

• Make sure that the calendar is not hidden. Look at the left hand side of the page under My calendars and Other calendars. If the calendar name doesn't have a colored bar running through it, it is hidden. Click on the calendar name to display it.

• Try adding the calendar again. Ask the owner to share the calendar id with you so you can add it again in the Add a coworkers calendar box.

• It's possible that the owner of the calendar (or another user with "manage sharing" rights) has deleted the calendar or removed your right to view the calendar.

• If you're receiving an error message like ‘Oops’ or ‘Loading,’ try the following:

  • Refresh the browser several times
  • Clear your browser's cache and cookies
  • Sign in and out of your Google Apps account

If other users can view your calendar, it's most likely because your domain administrator has chosen to make all user calendars available by default.

To override this setting:

1. Sign in to your calendar.
2. Find your calendar name in the My calendars section on the left.
3. Click the drop-down arrow by your calendar and then select Share this Calendar.
4. Make sure Share this calendar with others is not checked.

To learn more, see Share your calendar.

If you can't access a coworker's calendar, try these possible fixes:

• You can add a coworker's calendar to your calendar view by entering their email address in the Add a coworker’s calendar field. If their calendar is shared with your organization, you'll see the calendar automatically appear in your Other calendars list. Otherwise, you'll see a pop-up box where you can request access to the calendar.

• Make sure that the calendar is not hidden. Look at the left side of the page under Other calendars. If the calendar name doesn't have a colored bar running through it, the calendar is hidden. Just click the calendar name to display it.

• It's possible that the owner of the calendar has deleted the calendar or removed your right to view the calendar. Ask the calendar owner to share the calendar with you again if it still exists.

If you can't create an event, try these possible fixes:

1. If you're receiving an error message like ‘Oops’ or ‘Loading,’ try the following:

   • Refresh the browser several times.
   • Clear your browser's cache and cookies.
   • Sign in and out of your Google Apps account.

2. If you're receiving an error message like ‘Daily quota exceeded,’ you've surpassed the daily limit for creating and editing events. You can wait 24 hours and the limits will be reset to zero. If it's urgent and you can't wait:

   • If you're a Calendar user, contact your system administrator.
   • If you're a Google Apps administrator, contact support.

3. If you're not the primary owner of the calendar on which you're trying to add an event, make sure you have the right to create events on that calendar. The calendar owner might have previously granted you access to create events but then removed that access without notifying you. 

   To check your access level:

   1. Find the calendar in your My calendars list. If the calendar is not listed there, you'll need to have the calendar owner or system administrator check this for you.
   2. Click the drop-down arrow by the calendar and select Share this Calendar.
   3. Check your permission level. You need to have permission to Make changes to events or Make changes AND manage sharing in order to create an event on a calendar you don't own.

If you can't edit an event that you own, check these possible causes and fixes:

• Is the event on a shared calendar? It's possible that another user has removed your editing rights to the calendar and its events.

  To check:

  1. Find the calendar in your My calendars list. If the calendar is not listed there, you'll need to have the calendar owner or system administrator check this for you.
  2. Click the drop-down arrow by the calendar and select Share this Calendar.
  3. Check your permission level. You need to have permission to Make changes to events or Make changes AND manage sharing in order to create and edit events on a calendar you don't own.
