Updated June 3, 2025: We have updated the timeline below. Thank you for your patience.

Coming soon for Microsoft Outlook for iOS and Android users: In response to customer requests, we are rolling out the ability to attach emails directly in the compose window. This enhancement allows users to include individual emails as attachments in new messages, facilitating seamless sharing and providing more context for recipients.

This message is associated with Microsoft 365 Roadmap ID 464206.

[When this will happen:]

General Availability (Worldwide, GCC, GCC High): We will begin rolling out late January 2025 (previously early January) and expect to complete by mid-June 2025 (previously late May).

[How this will affect your organization:]

Before this rollout, users can forward emails as attachments but cannot attach emails while composing.

After this rollout, users will notice a new Attach email option when they select the paper clip attachment icon in the compose window. Users can select this option to browse for, choose, and attach individual emails to their new message.

This change is available by default.

[What you need to do to prepare:]

This change will happen automatically by the specified date. No admin action is required. Please notify your users about this change, update relevant documentation.
