The Purge switch specifies the action for the content search is to remove items that match the search criteria. You don't need to specify a value with this switch.

- A maximum of 10 items per mailbox can be removed at one time. Because the capability to search for and remove messages is intended to be an incident-response tool, this limit helps ensure that messages are quickly removed from mailboxes. This action isn't intended to clean up user mailboxes.

**Tip**: To purge more than 10 items, refer to [ediscoverySearch: purgeData](https://learn.microsoft.com/graph/api/security-ediscoverysearch-purgedata) in the Microsoft Graph API, which allows purging a maximum of 100 items per location.

- You can remove items from a maximum of 50,000 mailboxes using a single content search. To remove items from more than 50,000 mailboxes, you'll have to create separate content searches. For more information, see [Search for and delete email messages in your Microsoft 365 organization](https://learn.microsoft.com/purview/ediscovery-search-for-and-delete-email-messages).
- Unindexed items aren't removed from mailboxes when you use this switch.
- The value of the PurgeType parameter controls how the items are removed.
