Microsoft announced an upcoming enhancement to the External Recipients MailTips feature in Outlook for iOS and Android. This update is designed to improve the ability to distinguish between internal and external recipients, which is essential for maintaining secure and efficient communication.
Timeline
The rollout will begin in early January 2025 and is expected to be completed by late January 2025. This change will be enabled by default.
Impact on your organization
Following the rollout, organizations that have enabled the External Recipient MailTips feature will experience significant benefits. Outlook Mobile will retrieve and cache internal domain information from the Microsoft Exchange service, enhancing accuracy for users who are offline or have unreliable internet connections. This improvement will also boost the overall performance of the feature.
Previously, when users added recipients to an email while offline, Outlook for iOS and Android relied on domain comparison due to the inability to access the MailTips service. With this update, users can expect a more reliable experience, even in challenging connectivity situations.
