Configure the expiration policy for Microsoft 365 groups
This article tells you how to manage the lifecycle of Microsoft 365 groups by setting an expiration policy for them. You can set expiration policy only for Microsoft 365 groups in Azure Active Directory (Azure AD), part of Microsoft Entra.
Once you set a group to expire:
- Groups with user activities are automatically renewed as the expiration nears.
- Owners of the group are notified to renew the group, if the group is not auto-renewed.
- Any group that is not renewed is deleted.
- Any Microsoft 365 group that is deleted can be restored within 30 days by the group owners or the administrator.
Currently, only one expiration policy can be configured for all Microsoft 365 groups in an Azure AD organization.
Configuring and using the expiration policy for Microsoft 365 groups requires you to possess but not necessarily assign Azure AD Premium licenses for the members of all groups to which the expiration policy is applied.
For information on how to download and install the Azure AD PowerShell cmdlets, see Azure Active Directory PowerShell for Graph 126.96.36.199.
Activity-based automatic renewal
With Azure AD intelligence, groups are now automatically renewed based on whether they have been recently used. This feature eliminates the need for manual action by group owners, because it's based on user activity in groups across Microsoft 365 services like Outlook, SharePoint, Teams, or Yammer. For example, if an owner or a group member does something like upload a document to SharePoint, visit a Teams channel, send an email to the group in Outlook, or view a post in Yammer, the group is automatically renewed around 35 days before the group expires and the owner does not get any renewal notifications.
For example, consider an expiration policy that is set so that a group expires after 30 days of inactivity. However, to keep from sending an expiration email the day that group expiration is enabled (because there's no record activity yet), Azure AD first waits five days. If there is activity in those five days, the expiration policy works as expected. If there is no activity within five days, we send an expiration/renewal email. Of course, if the group was inactive for five days, an email was sent, and then the group was active, we will autorenew it and start the expiration period again.
Activities that automatically renew group expiration
The following user actions cause automatic group renewal:
- SharePoint: View, edit, download, move, share, or upload files
- Outlook: Join group, read/write group message from group space, Like a message (in Outlook Web Access)
- Teams: Visit a Teams channel
- Yammer: View a post within a Yammer community or an interactive email in Outlook
Auditing and reporting
Administrators can get a list of automatically renewed groups from the activity audit logs in Azure AD.
Roles and permissions
The following are roles that can configure and use expiration for Microsoft 365 groups in Azure AD.
|Global administrator, Group administrator, or User administrator||Can create, read, update, or delete the Microsoft 365 groups expiration policy settings
Can renew any Microsoft 365 group
|User||Can renew a Microsoft 365 group that they own
Can restore a Microsoft 365 group that they own
Can read the expiration policy settings
For more information on permissions to restore a deleted group, see Restore a deleted Microsoft 365 group in Azure Active Directory.
Set group expiration
Open the Azure portal with an account that is a Global Administrator in your Azure AD organization.
Browse to Azure Active Directory > Groups, then select Expiration to open the expiration settings.
On the Expiration page, you can:
- Set the group lifetime in days. You could select one of the preset values, or a custom value (should be 30 days or more).
- Specify an email address where the renewal and expiration notifications should be sent when a group has no owner.
- Select which Microsoft 365 groups expire. You can set expiration for:
- All Microsoft 365 groups
- A list of Selected Microsoft 365 groups
- None to restrict expiration for all groups
- Save your settings when you're done by selecting Save.
- When you first set up expiration, any groups that are older than the expiration interval are set to 35 days until expiration unless the group is automatically renewed or the owner renews it.
- When a dynamic group is deleted and restored, it's seen as a new group and re-populated according to the rule. This process can take up to 24 hours.
- Expiration notices for groups used in Teams appear in the Teams Owners feed.
- When you enable expiration for selected groups, you can add up to 500 groups to the list. If you need to add more than 500 groups, you can enable expiration for all your groups. In that scenario, the 500-group limitation doesn't apply.
If groups are not automatically renewed, email notifications such as this one are sent to the Microsoft 365 group owners 30 days, 15 days, and 1 day prior to expiration of the group. The language of the email is determined by groups owner's preferred language or Azure AD language setting. If the group owner has defined a preferred language, or multiple owners have the same preferred language, then that language is used. For all other cases, Azure AD language setting is used.
From the Renew group notification email, group owners can directly access the group details page in the Access Panel. There, the users can get more information about the group such as its description, when it was last renewed, when it will expire, and also the ability to renew the group. The group details page now also includes links to the Microsoft 365 group resources, so that the group owner can conveniently view the content and activity in their group.
If there is any problem with the notification emails, and they aren't sent out or they are delayed, be assured that Microsoft will never delete a group before the last email is sent.
When a group expires, the group is deleted one day after the expiration date. An email notification such as this one is sent to the Microsoft 365 group owners informing them about the expiration and subsequent deletion of their Microsoft 365 group.
The group can be restored within 30 days of its deletion by selecting Restore group or by using PowerShell cmdlets, as described in Restore a deleted Microsoft 365 group in Azure Active Directory. Please note that the 30-day group restoration period is not customizable.
If the group you're restoring contains documents, SharePoint sites, or other persistent objects, it might take up to 24 hours to fully restore the group and its contents.
How to retrieve Microsoft 365 group expiration date
In addition to Access Panel where users can view group details including expiration date and last renewed date, expiration date of a Microsoft 365 group can be retrieved from Microsoft Graph REST API Beta. expirationDateTime as a group property has been enabled in Microsoft Graph Beta. It can be retrieved with a GET request. For more details, please refer to this example.
In order to manage group memberships on Access Panel, "Restrict access to Groups in Access Panel" needs to be set to "No" in Azure Active Directory Groups General Setting.
How Microsoft 365 group expiration works with a mailbox on legal hold
When a group expires and is deleted, then 30 days after deletion the group's data from apps like Planner, Sites, or Teams is permanently deleted, but the group mailbox that is on legal hold is retained and is not permanently deleted. The administrator can use Exchange cmdlets to restore the mailbox to fetch the data.
How Microsoft 365 group expiration works with retention policy
The retention policy is configured by way of the Security & Compliance Center. If you have set up a retention policy for Microsoft 365 groups, when a group expires and is deleted, the group conversations in the group mailbox and files in the group site are retained in the retention container for the specific number of days defined in the retention policy. Users won't see the group or its content after expiration, but can recover the site and mailbox data via e-discovery.
Here are examples of how you can use PowerShell cmdlets to configure the expiration settings for Microsoft 365 groups in your Azure AD organization:
Install the PowerShell v2.0 module and sign in at the PowerShell prompt:
Install-Module -Name AzureAD Connect-AzureAD
Configure the expiration settings Use the New-AzureADMSGroupLifecyclePolicy cmdlet to set the lifetime for all Microsoft 365 groups in the Azure AD organization to 365 days. Renewal notifications for Microsoft 365 groups without owners will be sent to 'email@example.com'
New-AzureADMSGroupLifecyclePolicy -GroupLifetimeInDays 365 -ManagedGroupTypes All -AlternateNotificationEmails firstname.lastname@example.org
Retrieve the existing policy Get-AzureADMSGroupLifecyclePolicy: This cmdlet retrieves the current Microsoft 365 group expiration settings that have been configured. In this example, you can see:
- The policy ID
- The lifetime for all Microsoft 365 groups in the Azure AD organization is set to 365 days
- Renewal notifications for Microsoft 365 groups without owners will be sent to 'email@example.com.'
Get-AzureADMSGroupLifecyclePolicy ID GroupLifetimeInDays ManagedGroupTypes AlternateNotificationEmails -- ------------------- ----------------- --------------------------- 26fcc232-d1c3-4375-b68d-15c296f1f077 365 All firstname.lastname@example.org
Update the existing policy Set-AzureADMSGroupLifecyclePolicy: This cmdlet is used to update an existing policy. In the example below, the group lifetime in the existing policy is changed from 365 days to 180 days.
Set-AzureADMSGroupLifecyclePolicy -Id "26fcc232-d1c3-4375-b68d-15c296f1f077" -GroupLifetimeInDays 180 -AlternateNotificationEmails "email@example.com"
Add specific groups to the policy Add-AzureADMSLifecyclePolicyGroup: This cmdlet adds a group to the lifecycle policy. As an example:
Add-AzureADMSLifecyclePolicyGroup -Id "26fcc232-d1c3-4375-b68d-15c296f1f077" -groupId "cffd97bd-6b91-4c4e-b553-6918a320211c"
Remove the existing Policy Remove-AzureADMSGroupLifecyclePolicy: This cmdlet deletes the Microsoft 365 group expiration settings but requires the policy ID. This cmdlet disables expiration for Microsoft 365 groups.
Remove-AzureADMSGroupLifecyclePolicy -Id "26fcc232-d1c3-4375-b68d-15c296f1f077"
The following cmdlets can be used to configure the policy in more detail. For more information, see PowerShell documentation.
