Recall actions are typically quick, regardless of how many recipients are involved. However, if the recall request can not be executed right away for some reason (e.g., the recipient’s mailbox is temporarily unavailable) it'll continue to retry for up to 24 hours before marking the recall as failed.

The time to receive status updates can vary. For a very large number of recipients (thousands), the recall itself can take up to 30 minutes to retrieve the recall status for all recipients.
