The New Outlook August 2026 update has finished rolling out, and Microsoft has packed in a batch of small-but-useful tweaks. The biggest talking point — the long-awaited “All inboxes” view — still isn’t live for everyone, but several other improvements have landed. Here’s everything that changed according to Windows Latest.
Status on the headline feature: Before we get to the five shipped changes, here’s where the “All inboxes” view stands. Microsoft says it’s still rolling out and is gated behind “Controlled Feature Rollout,” which deliberately limits access to reduce potential issues. So if you haven’t seen it yet, that’s expected behavior, not a bug.
#1 Delete up to 100 contacts at once
New Outlook now lets you delete up to 100 contacts in a single batch. Previously, the ceiling was just 10, which was a real annoyance for anyone with a large address book. For comparison, Outlook Classic has no such limit and lets you delete as many contacts as you want in one go — a flexibility New Outlook still doesn’t match, at least not yet.
In practice, this means you can finally clean up a merged or migrated address book without chipping away at it 10 at a time. It’s a meaningful step forward, even if it hasn’t fully caught up to the legacy app.
#2 Quick Parts moves to the right-click menu
Quick Parts lets you store reusable blocks of text and drop them into new messages. It’s one of the most useful features in a corporate setup, where you constantly resend the same office address, signature block, or standard disclaimer. In effect, you’re configuring a template and importing it into newer emails so you don’t have to retype it.
The feature was added to New Outlook a while back, but it lived inside the ribbon menu, forcing you to move the cursor around, locate the reusable piece, and insert it. Now you can right-click anywhere while drafting an email and add a Quick Part directly from the context menu. You can even save new content as a Quick Part from that same menu, keeping the whole workflow in one place.
#3 Ctrl+Y jumps to any folder
You can now press Ctrl+Y to open the “Go to Folder” dialog, with the cursor automatically placed in the search box so you can start typing immediately. Alternatively, you can pick a folder from the dropdown. It’s a small efficiency gain, but one power users will notice right away.
This update also tightens offline support. Microsoft has been working to make New Outlook — which runs on a web-based wrapper rather than a native client — more usable without a connection. It recently added the ability to attach files while offline, and now you can also view the Focused and Other inbox views while disconnected.
#4 A fourth column in your message list
When you apply filters or sort your message list, Outlook now shows a fourth content column. This gives you a bit more room to scan sender, subject, and additional details without cramming everything into fewer columns — a subtle but welcome change for anyone with a dense inbox.
New Outlook August 2026: what’s still coming
The “All inboxes” view is the marquee feature. It lets you pull in multiple Outlook inboxes on a single screen and manage everything — delete, move, favorite, forward, and the other options you’d expect from a normal inbox — from one place. Instead of a single inbox, you’ll see content from all your mailboxes in one spot. It’s still rolling out, so don’t expect it tomorrow.
Microsoft is also working on transferring ownership of a meeting or recurring meeting series to someone else in your organization. The new organizer has to accept the transfer before it completes, and it works across Outlook for Windows, Outlook on the web, and Teams calendar. That’s handy for long-running meetings where the original organizer has moved on.
The offline settings are getting a new “Days of email to save” option. By default, Outlook keeps emails and attachments for up to 30 days offline; you can bump that to 180, or dial it down to 7 or 60 days. It lives under Settings > General > Offline. Tenant admins can set the default value and decide whether users are allowed to change it — a detail IT teams managing a fleet will want to note.
Finally, you’ll be able to manage multiple inbox rules at once. You can select all rules or just the ones you want, then delete, enable, or disable them in a single action instead of editing each rule individually.
What this means for you
For most users, the shipped changes are quality-of-life wins: fewer clicks to reuse text, faster folder navigation, and a bit more room in a crowded message list. The contact-deletion cap is still a step behind Outlook Classic, so don’t hold your breath on full parity.
If you rely on offline access, the ability to read Focused and Other views without a connection is the most practical gain of the bunch, given how New Outlook still depends on a web wrapper rather than a native build.
How to get it
The August 2026 update is rolling out now. If you haven’t seen the new features yet, make sure New Outlook is up to date in Settings, and be patient with the “All inboxes” view — Controlled Feature Rollout means it will reach you in its own time.
