When you save a new event, Virto Shared Calendar may show this message under the event form:

> You have reached the maximum number (15) of calendar entries.

The event is not saved. This page explains why and what to do.

## Why the message appears

The Free plan of Virto Shared Calendar allows **up to 15 entries in each calendar**. You can create as many calendars as you like, and each one can hold 15 entries.

When a calendar already has 15 entries, only a user covered by a paid license can add more to it. The message appears when the person saving the event is not covered by a valid license, for one of these reasons:

- your organization uses the Free plan;
- the paid license has expired;
- your organization has a license for a set number of users, and your account is not one of the licensed users;
- the license was bought, but Virto Shared Calendar does not see it for your organization yet.

People who only **view** calendars never need a license, on any plan.

## If you are on the Free plan

A license is required for every user who creates or edits calendars with more than 15 entries. Open **Shared Calendar** > **Subscription** and click **Purchase**, or see the plans on the [Virto Shared Calendar product page](https://www.virtosoftware.com/microsoft-teams/virto-teams-shared-calendar/).

You can also keep the calendar on the Free plan: delete entries you no longer need, or start a new calendar for the next period.

## If you have already bought a license

1. Open Virto Shared Calendar in Microsoft Teams or in the browser.
2. Go to the **Shared Calendar** tab and click **Subscription**. Opening this page reads your license from VirtoSoftware again.
3. Check the fields on the page:
   - **Edition** should no longer say **Free**.
   - **License status** should be valid, not **Expired** or **Invalid**.
   - **Domain** is your organization's SharePoint domain, for example `contoso.sharepoint.com`. The license belongs to this domain.
   - **Expires on** shows the end of the paid period.
4. If your license covers a set number of users, the page shows **Users count**, for example `3/5`. Add every person who creates or edits events to the licensed users. A user who is not on that list still gets the 15-entry limit. A license for unlimited users does not need this step.
5. Go back to the calendar and save the event again.

There is no field for a license key in Virto Shared Calendar. If you received a key or an order number by email and the **Subscription** page still shows the **Free** edition, send the order number and your SharePoint domain to [support@virtosoftware.com](mailto:support@virtosoftware.com).

## If the license has expired

The calendar shows "Your license is expired. Please renew your subscription." A calendar with more than 15 entries then stays visible, but its events can no longer be added or edited. Renew from the **Subscription** page. Events you already created stay in the calendar.
