explanation for non-techies**

Outlook Mobile is introducing a new feature that allows users to customize the toolbar when selecting multiple emails. Imagine this like rearranging the tools in your toolbox so that the ones you use most often are right at your fingertips. This change means you can decide which actions, such as moving emails to a different folder, reporting junk, ignoring conversations, pinning important messages, or snoozing emails for later, appear first when you select multiple emails.

The rollout for this feature will begin in mid-January 2026 and finish by mid-February 2026. There's no need for any administrative actions or concerns about compliance with this update. It's designed to be straightforward and user-friendly, much like organizing your desk to make your workday more efficient.

To customize the toolbar, users will simply tap an overflow menu and then drag and drop the actions into their preferred order. This is similar to organizing apps on your smartphone's home screen by dragging them into the order that makes the most sense for you. Some actions may be disabled when selecting multiple emails because they can only be applied to one email at a time, but this is clearly indicated in the app.

Overall, this update is about giving users more control over their email management tools, making it easier to handle multiple messages efficiently without any extra steps or complications.
