Reactivate mailboxes (Microsoft 365 / Azure)

Reactivate Microsoft 365 and Azure mailboxes that are scheduled for cancellation or whose renewal failed. For Google Workspace mailboxes, use Uncancel mailboxes instead.

Eligible mailboxes

Platform is Microsoft 365 or Azure

Status is scheduled_for_cancellation or renewal_failed

Within 30 days of the renewal date (or of the failed renewal)

How it works

Reactivation runs in the background. This call only queues the mailboxes and returns right away. Follow progress with mailbox_reactivation_status on List mailboxes, Get mailbox details or Check mailbox status. Most reactivations complete within a few minutes.

Outcome	What happens	Charge
License still active	Mailbox returns to `active`, `mailbox_reactivation_status` becomes `completed`	None
License expired	We re-purchase it automatically and set the mailbox up again. `status` moves to `processing`, then `active`	Normal purchase price, from your wallet
License expired, wallet balance too low	Paused with `mailbox_reactivation_status: needs_rebuy`. Top up your wallet and call Re-purchase mailboxes for reactivation	Charged when you call it
Could not be reactivated	`mailbox_reactivation_status: permanently_failed`. Contact support	None

Billing

Reactivating a mailbox whose renewal failed does not waive that renewal. It is charged automatically once the mailbox is active again.

A re-purchase is priced like a new purchase: per mailbox for Microsoft 365, per domain for Azure.

The request always returns 200 when it is valid, even if every mailbox fails. Check results.failed for per-mailbox reasons:
