This cmdlet is available only in the cloud-based service.

Use the Remove-Subscription cmdlet to remove a Hotmail, POP, or IMAP subscription from a user's cloud-based mailbox.

For information about the parameter sets in the Syntax section below, see Syntax.

Remove-Subscription -Identity <AggregationSubscriptionIdParameter> [-Mailbox <MailboxIdParameter>] [-Confirm [<SwitchParameter>]] [-WhatIf [<SwitchParameter>]]

This example removes the subscription Contoso from the mailbox of the user Kim Akers.

Remove-Subscription Contoso -Mailbox "Kim Akers"

The Remove-Subscription cmdlet removes a Hotmail, POP, or IMAP subscription from a user's cloud-based mailbox. It doesn't remove the email messages or contacts previously downloaded to the cloud-based mailbox by the subscription.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Subscriptions" entry in the Feature permissions in Exchange Online topic.


Parameter Required Type Description




The Identity parameter specifies the subscription. You can identify the subscription by using one of the following methods:

  • Specify the globally unique identifier of the subscription, which is its canonical name (CN).

  • Use the Mailbox parameter to specify the mailbox that contains the subscription, and then specify the name of the subscription.

You can find the identifying values for a subscription, such as Identity and Name, by running this command: Get-Subscription -Mailbox <mailbox>.




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.




The Mailbox parameter specifies the cloud-based mailbox that contains the subscription. You can use any value that uniquely identifies the mailbox.

For example:

  • Name

  • Display name

  • Alias

  • Distinguished name (DN)

  • Canonical DN

  • <domain name>\<account name>

  • Email address

  • GUID

  • LegacyExchangeDN

  • SamAccountName

  • User ID or user principal name (UPN)




The WhatIf switch simulates the actions of the command. You can use this switch to view the changes that would occur without actually applying those changes. You don't need to specify a value with this switch.
