M365 Changelog: Outlook mobile clients will soon provide access to delegate mailboxes

MC250343 – Your end users will soon be able to add and remove delegates from within Outlook for iOS and Outlook for Android. Delegates will be able to access those mailboxes on their mobile app as well.

This message is associated with Microsoft 365 Roadmap ID 67273 and 67274.

When this will happen

Rollout begins in late April and should be complete in early May.

How this will affect your organization

A delegate mailbox is a mailbox where users can provide access for others (delegates) to take actions on their behalf.

With this update, users can manage delegates from within their Outlook mobile app. Colleagues with delegate permissions can add and view delegate mailboxes in their Outlook mobile app.


What you need to do to prepare

You might want to notify your users about this new capability and update your training and documentation as appropriate.
