# Teams Channels shall have an expiration policy

## Description

Organizations with a large number of Teams often have Teams channels that are never actually used. This can happen because of several reasons including product experimentation, short-term team collaboration, or team owners leaving the organization. Over time, such teams can accumulate and create a burden on tenant resources. To curb the number of unused teams, as an admin, you can use group expiration policy to automatically clean up unused teams. Because teams are backed by groups, group expiration policies automatically apply to teams as well.

## Policy

*  Teams channels shall have an expiration policy for inactivity

## Licensing Considerations

There are no licensing considerations for modifying the group expiration policy.

To define group expiration policies, follow the steps listed [here](https://learn.microsoft.com/en-us/microsoft-365/solutions/microsoft-365-groups-expiration-policy?view=o365-worldwide#how-to-set-the-expiration-policy)

## End-User Impact

{% hint style="info" %}
Level: <mark style="color:yellow;">Medium</mark>
{% endhint %}

When you apply an expiration policy to a team, a team owner receives a notification for team renewal 30 days, 15 days and 1 day before the team's expiration date. When the team owner receives the notification, they can click Renew now in team settings to renew the team. To prevent accidental deletion, auto-renewal is automatically enabled for a Team in the group expiration policy. When the group expiration policy is set up, any team that has at least one channel visit from any team member before its expiration date is automatically renewed without any manual intervention from the team owner.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.tminus365.com/security/teams/teams-channels-shall-have-an-expiration-policy.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
