Syntax
Undo-SoftDeletedUnifiedGroup
[-SoftDeletedObject] <UnifiedGroupIdParameter>
[-Confirm]
[-WhatIf]
[<CommonParameters>] Description
Microsoft 365 Groups are group objects that are available across Microsoft 365 services.
Soft-deleted Microsoft 365 Groups are groups that have been deleted, but can be restored within 30 days of being deleted. All of the group contents can be restored within this period. After 30 days, soft-deleted Microsoft 365 Groups are marked for permanent deletion and can't be restored.
To display all soft-deleted Microsoft 365 Groups in your organization, use the Get-MgDirectoryDeletedItemAsGroup cmdlet in Microsoft Graph PowerShell. To permanently remove (purge) a soft-deleted Microsoft 365 Group, use the Remove-MgDirectoryDeletedItem cmdlet in Microsoft Graph PowerShell.
You need to be assigned permissions before you can run this cmdlet. Although this topic lists all parameters for the cmdlet, you may not have access to some parameters if they're not included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.
Examples
Example 1

Parameters
-Confirm
The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.
- Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax:
-Confirm:$false. - Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.
| Type: | SwitchParameter |

-SoftDeletedObject
The SoftDeletedObject parameter specifies the soft-deleted Microsoft 365 Group that you want to restore. You can use any value that uniquely identifies the Microsoft 365 Group. For example:
- Name
- Alias
- Distinguished name (DN)
- Canonical DN
- Domain\Username
- Email address
- GUID
- LegacyExchangeDN
- SamAccountName
- User ID or user principal name (UPN)
Note: You might need to use the DistinguishedName or ExchangeGuid property to identify the soft-deleted Microsoft 365 Group, because it's possible for an active Microsoft 365 Group and a soft-deleted Microsoft 365 Group to have the same primary SMTP address.
