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

MC519224 – 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.

When this will happen:

Microsoft started rolling it out mid-February and expects to complete the roll-out by 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
