Microsoft Adds Cross-Tenant Message Recall to Exchange Online
Microsoft has introduced cross-tenant message recall for Exchange Online, extending its email recall capability beyond a single Microsoft 365 organization. Message Recall operates within the Exchange Online service boundary, and until now it has been limited to intra-tenant messages, those where the sender and the recipients belong to the same Microsoft 365 tenant. With Cross-Tenant Message Recall, a tenant admin can add other Microsoft 365 tenants to an allow list.
The feature allows users to attempt to recall messages sent to recipients in another Microsoft 365 tenant, provided both organizations use Exchange Online and meet the required configuration and eligibility conditions. Previously, message recall was generally limited to recipients within the same organization. Consider two organizations that work together, Contoso and Fabrikam, both of whom are hosted in Microsoft 365. Admins can configure these settings using Exchange Online PowerShell.
Microsoft said the enhancement is designed to improve collaboration between businesses that communicate frequently across organizational boundaries while giving users an opportunity to retract messages sent in error. Administrators retain control over the feature through Exchange Online policies and configuration settings. Cross-Tenant Message Recall will start to deploy to worldwide, GCC, GCC High, DoD and Microsoft 365 operated by 21Vianet starting mid-August, completing by mid-September.
