Avoid Calendar use limits

Google sets use limits to protect Google Calendar users, admins, and organizations from abusive behavior. These limits are higher than the typical activity of Calendar users. If a user in your organization performs an action too many times, they won't be able to do that same action again for a few hours.

Use-limit errors

  • Unable to save event. This message means that the user reached the limit for the number of events that they can edit.
  • There was a problem saving your changes. Please try again in a few minutes. A description of the limit reached follows this message.

Limits for free & trial accounts

To protect users from spam, we don't publicize exact limits. However, subscription account limits are higher than limits for trial accounts or the legacy free edition of G Suite. If needed, you can end your trial and convert to a paid account. For details, go to Set up Google Workspace billing.

Add usage to paid accounts

Your use limits don't increase immediately after you convert to a paid account. To increase your trial limits to subscription account limits:

  1. Buy your domain.
  2. Pay the cumulative equivalent of at least USD 100 more than the cost of your domain. For details, go to Make a manual payment or pay early.
  3. Wait 60 days.

60 days after you reach the payment threshold, your use limits increase.

Usage guidelines

Limit Time to replenish
If users create more than 100,000 events during a short period, they might lose the ability to edit events for a few hours. Possibly several months
Do not create more than 60 calendars in a short period. Possibly several hours
To prevent spamming, Calendar limits the number of invitations a user can send to external guests. If a user sends 10,000 invites to people outside of their primary or secondary domain in a short period, the user might not be able to send external invitations for a few hours. Possibly several days

To prevent spamming, a user can send about 2,000 emails to external guests using the Email guests feature.

Using this feature with users in your primary or secondary domain does not count toward this limit.
Within 24 hours
Do not share calendars with many users in a short period (750 shares). Possibly several hours
