How to Pin Mail in Outlook: Classic, New Outlook, and Mobile App

Your inbox moves fast. One important email can slip under fifty new ones before lunch. That’s why so many people search for how to pin mail in Outlook, so key messages stay put at the top.

Here’s the catch: the pin feature doesn’t work the same way everywhere. Some versions have it. Others, like classic Outlook for Windows, don’t. That’s why many users say the pin option is missing.

In this guide, you’ll learn how to pin emails in new Outlook, Outlook on the web, and the mobile app. We’ll also cover how to pin emails in classic Outlook using smart workarounds. Let’s get your inbox under control.

1. Can You Pin Emails in Outlook?

Yes, but only in some versions. Microsoft explains in its guide to flagging or pinning a message that a pinned message moves to the top of your inbox so it’s easy to find later.

Here’s where pinning works:

Outlook Version	Pin Available?
New Outlook for Windows	Yes
Outlook for Mac	Yes
Outlook on the web / Outlook.com	Yes
Outlook mobile (iOS and Android)	Yes (Microsoft 365 and Outlook.com accounts)
Classic Outlook for Windows	No

So, can you pin emails in Outlook desktop app? It depends. The new app can. The classic app can’t. A Microsoft Community moderator confirmed this limit for classic Outlook.

2. How to Pin Mail in Outlook (New Outlook and Web)

These steps also answer how to pin mail in Outlook 365 and how to put an email on top in Outlook.

In New Outlook for Windows or Mac

1. Open your inbox.
2. Hover over the email you want to keep on top.
3. Click the pin icon that appears.
4. Check the top of your list. The message now sits in the pinned area.

You can also right-click the message and choose Pin. To undo it, click the pin icon again.

In Outlook on the Web

1. Sign in at outlook.office.com or outlook.com.
2. Sort your inbox by date. Microsoft says pinned messages only show when the inbox is sorted this way.
3. Hover over a message and click the pin icon.

Handy to know: Pins sync with your mailbox. A message pinned on the web should also show as pinned in new Outlook and the mobile app.

3. How to Pin Mail in Outlook App (Android and iPhone)

Looking for how to pin mail in Outlook Android or how to pin mail in Outlook on iPhone? The steps are almost the same.

1. Open the Outlook app and tap the email.
2. Tap the three dots at the top right.
3. Choose Pin.

For a faster way, use a swipe action:

1. Go to Settings > Swipe Options.
2. Set Swipe Left or Swipe Right to Pin/Unpin.
3. Swipe any message to pin it in one move.

To see only your pinned emails, tap the Pinned filter at the top of the message list.

4. How to Pin Emails in Classic Outlook

Now for the question many readers ask: how to pin mail in Outlook classic? Sadly, classic Outlook for Windows has no pin button. This also answers how to pin mail in Outlook desktop app if you use the older version. The good news is that three workarounds come close.

Option A: Flag and Sort

1. Right-click the email and choose Follow Up, then pick a flag.
2. Go to the View tab.
3. In the arrangement options, choose Flag: Due Date or Flag Status.

Flagged messages now rise to the top of your list.

Option B: Use Color Categories

1. Right-click the message and pick Categorize.
2. Choose a bright color, such as red.
3. On the View tab, arrange by Categories.

Option C: Create a Quick Step or Search Folder

• Build a Quick Step that moves key emails into a folder called “Pinned.”
• Or open the built-in For Follow Up search folder to see all flagged mail in one place.

Prefer a real pin? Switch to new Outlook (use the toggle in the top-right corner) or open Outlook on the web.

5. Why Can’t I See the Pin Option?

Is your pin option not showing in Outlook 365? Or do you wonder why you can’t pin emails in the Outlook desktop app? Check these causes:

• You’re on classic Outlook. This is the most common reason.
• Your inbox isn’t sorted by date. Switch the sort order, then try again.
• You’re on an older app version. Update Outlook and restart it.
• Your account type doesn’t support it. Mobile pinning works for Microsoft 365 and Outlook.com accounts. Other account types may behave differently.
• You didn’t hover. In many views, the pin icon only appears when you hover over a message.

6. Flag vs Pin: What’s the Difference?

People often ask about the flag email in Outlook meaning. A flag tells you “follow up on this later.” A pin keeps a message at the top of your inbox.

Feature	Flag	Pin
Purpose	Mark for follow-up	Keep at top
Moves email to top	No (unless you sort by flag)	Yes
Can add a due date	Yes	No
Works in classic Outlook	Yes	No

Use both together for your most important tasks.

7. How to Pin a Mailbox or Outlook to the Taskbar

How do I pin a mailbox in Outlook? You can’t pin a mailbox like a message. But you can add a mailbox or folder to Favorites for quick access. This works well for shared inboxes. If you’re unsure how they differ, read shared mailbox vs user mailbox in Microsoft 365.

How to pin an email to the Outlook taskbar? Windows can’t pin a single email, but you can pin the app itself:

1. Click Start and find Outlook.
2. Right-click it and choose Pin to taskbar.

8. Quick Tips and Common Mistakes

• Don’t over-pin. If everything is pinned, nothing stands out. Keep it to five messages or fewer.
• Unpin when done. Clear finished items daily.
• Press Home in the message list to jump to the top of your Outlook email quickly.
• Check for missing mail first. If a message never arrived, see our post on Outlook email not receiving emails.
• Don’t forget Copilot. Newer tools can summarize long threads. See how to use Microsoft Copilot in Outlook and Teams.

9. FAQs

Why can’t I see the PIN option in Outlook?
You’re likely using classic Outlook for Windows, which doesn’t support pinning. Your inbox must also be sorted by date. Switch to new Outlook or Outlook on the web, and the pin icon appears when you hover over a message.

How do I pin emails to the top?
In new Outlook or Outlook on the web, hover over the message and click the pin icon, or right-click and choose Pin. The email then moves to the top of your inbox until you unpin it.

How do I pin a mailbox in Outlook?
You can’t pin a mailbox the way you pin an email. Instead, add the mailbox or folder to Favorites for quick access. Shared mailbox folders can be added to Favorites in much the same way.

How do I put an email on top in Outlook?
Pin it in new Outlook, the web app, or the mobile app. In classic Outlook, flag it and sort by flag status, or apply a color category and sort by category so important mail rises to the top.

How do I move my inbox to the top in Outlook?
Sort your message list by date with the newest mail first, so recent messages sit at the top. To bring a whole mailbox higher in the folder list, set it as your default account in Account Settings.

Can you pin emails in Outlook desktop app?
It depends on the version. New Outlook for Windows and Outlook for Mac support pinning, but classic Outlook for Windows does not. In classic, use flags, categories, or search folders, or switch to new Outlook to pin.

What does flag email in Outlook mean?
A flag marks an email for follow-up. It adds a visual cue and can carry a due date, but it doesn’t move the message to the top. Pinning keeps a message at the top of the inbox.
