M365 Changelog: (Updated) New Message Recall in Exchange Online rolling out now

MC519224 – Updated March 28, 2023: Microsoft has updated the rollout timeline below. Thank you for your patience.

The new Message Recall feature in Exchange Online is starting to roll out now and should be available to all Exchange Online tenants worldwide by mid-March. The new feature is more than twice as effective at successfully recalling messages than the classic Outlook for Windows Message Recall feature, and offers a single aggregated recall status report for each recall.

This message is associated with Microsoft 365 Roadmap ID 59438

When this will happen:

Microsoft started rolling it out mid-February and expect to complete the roll-out by early April (previously mid-March).

How this will affect your organization:

When your organization’s users with mailboxes hosted in Exchange Online try to recall a message we’ll use the new cloud-based message recall feature to recall the message instead of the classic Outlook for Windows client based feature. Your end-users will experience significantly higher recall rates than ever before, typically > 95% for messages to recipients within the organization.

What you need to do to prepare:

There’s nothing you need to do for your end-users to take advantage of this functionality, it’s automatically done for them in the cloud.

However, should you wish to disable the new cloud-based Message Recall for your organization, or disable recalling read messages, you can use the following Remote PowerShell cmdlets:

  • Disable the new Message Recall for your entire tenant: Set-OrganizationConfig -MessageRecallEnabled $false
  • Disable recalling read messages: Set-OrganizationConfig -RecallReadMessagesEnabled $false

The setting to disable recalling read messages is also available in the Exchange Admin Center: EAC > Settings > Mail flow
