How To Mark Email Urgent In Outlook

When every second counts, marking a message as urgent ensures your team sees it before the rest of their inbox. Knowing how to mark email urgent in outlook can be the difference between a missed deadline and a swift response. This guide covers every method, from desktop to mobile, so you never have to worry about your important messages getting buried.

Urgent emails demand immediate attention. Outlook gives you a simple way to flag your message with a red exclamation mark, signaling priority. Let’s get straight into the steps.

This section walks you through the most common ways to set urgency on your emails. Whether you use Outlook for Windows, Mac, or the web version, the process is quick and intuitive.

Using The Desktop Version (Windows)

Outlook for Windows is the most popular version. Here’s how to mark an email as urgent before sending.

Open a new email message or reply to an existing one.
Go to the Message tab in the ribbon at the top.
Look for the Tags group. You’ll see a red exclamation mark icon labeled High Importance.
Click the icon once. It will highlight to show it’s active.
Compose your message and hit Send.

That’s it. The recipient will see a red exclamation mark next to your email in their inbox. It also appears in the reading pane.

You can also set urgency from the Options tab. Click More Options and then select High Importance from the dropdown menu. This is usefull if you prefer using the classic ribbon layout.

Using Outlook For Mac

Mac users have a slightly different interface, but the steps are just as simple.

Start a new email in Outlook for Mac.
Click the Options tab in the ribbon.
Find the Priority dropdown menu. It’s usually near the top right.
Select High from the list.
Finish your email and send it.

Alternatively, you can use the toolbar button. Look for the red exclamation mark icon in the compose window. Clicking it toggles the high importance flag on and off.

One tip: If you send a lot of urgent emails, you can add the priority button to your quick access toolbar for one-click access. Right-click the icon and choose Add to Quick Access Toolbar.

Using Outlook On The Web (OWA)

Outlook on the web works in your browser. It’s great for when you’re away from your main computer.

Log into your Outlook account online.
Click New Message to start composing.
In the compose window, look for the three-dot menu (More options) at the bottom.
Click it and select Show message options.
Under Priority, choose High.
Close the options panel and send your email.

Some versions of OWA have a direct button for high importance. It looks like a red exclamation mark in the toolbar. If you see it, just click it before sending.

Remember, the web version might not show the urgency flag to all recipients if they use a different email client. But within Outlook, it works perfectly.

Using The Outlook Mobile App (IOS And Android)

On your phone, marking an email urgent is a bit hidden, but it’s there.

Open the Outlook app and tap the compose button (pencil icon).
Tap the three-dot menu (More) in the top right of the compose screen.
Scroll down and toggle High Importance on.
Compose your message and send.

On some Android devices, you might see a flag icon directly in the toolbar. If not, use the menu option. The recipient will see the red exclamation mark in their mobile inbox.

One common mistake: The mobile app sometimes hides the urgency setting under the Format options. If you don’t see it, tap the Format button (A with a pencil) and look for the flag icon there.

Setting Urgency For Existing Emails In Your Inbox

What if you already recieved an email and want to mark it as urgent for yourself? Outlook lets you flag messages for follow-up, which is different from sending urgency.

Flagging Vs. Marking As Urgent

Flagging an email adds a reminder or a to-do item. It does not change the priority for the sender. Marking an email as urgent, on the other hand, tells the recipient to act immediately.

To flag an email you recieved:

Right-click the email in your inbox.
Select Follow Up and choose a flag type (Today, Tomorrow, etc.).
The email gets a colored flag icon. This is only for your own tracking.

If you want to change the urgency of an email you already sent, you cannot. You have to resend it with the high importance flag. Or send a follow-up message marked urgent.

Using Quick Steps For Urgency

Outlook’s Quick Steps feature can automate the process. You can create a one-click button that marks an email as urgent and moves it to a specific folder.

Go to the Home tab in Outlook.
Click the Quick Steps dropdown and select New Quick Step.
Choose Custom.
Name it something like “Mark Urgent.”
Under Actions, click Add Action.
Select Set Importance and choose High.
Optionally add another action, like moving to a folder.
Click Finish.

Now you can select any email in your inbox and click this Quick Step to mark it urgent for yourself. This is handy for organizing your own workflow.

Keyboard Shortcuts For Urgency

Speed matters when you’re in a rush. Outlook offers keyboard shortcuts to set high importance without touching your mouse.

Windows Shortcut

While composing a new email, press Alt + H + P + H on your keyboard.
This sequence activates the High Importance button from the ribbon.

Alternatively, you can use the classic shortcut: Ctrl + Alt + H (this works in older versions). Test which one works in your version.

Mac Shortcut

On a Mac, press Command + Shift + H while composing.
This toggles the high importance flag on and off.

These shortcuts save time, especially if you send multiple urgent emails daily. Practice them a few times and they’ll become second nature.

Best Practices For Using Urgency

Marking every email as urgent dilutes the meaning. Use it sparingly and only when truly needed.

When To Use High Importance

Time-sensitive deadlines that are hours away.
Critical system outages or security alerts.
Urgent approvals needed before a meeting.
Emergency requests from your manager or client.

When Not To Use It

Routine updates or status reports.
Non-urgent questions that can wait a day.
Emails sent to a large distribution list.
Personal messages that are not work-related.

Overusing the urgent flag can lead to recipients ignoring it. Reserve it for genuine emergencies. Also, consider adding a clear subject line like “URGENT: Server Down” to reinforce the priority.

Troubleshooting Common Issues

Sometimes the urgency flag doesn’t work as expected. Here are fixes for common problems.

Urgency Flag Not Showing In Recipient’s Inbox

Check if the recipient uses a different email client (Gmail, Yahoo). Urgency flags are not universal.
Ensure you clicked the High Importance button before sending. Double-check the flag icon is highlighted.
Some email servers strip the priority header. This is rare but possible.

Cannot Find The High Importance Button

Your ribbon might be collapsed. Click the small arrow at the top right to expand it.
Switch to the classic ribbon view if you’re using the simplified ribbon.
Search for “importance” in the Help bar at the top.

Urgency Flag Not Working On Mobile

Make sure you’re using the official Outlook app, not the default mail app.
Update the app to the latest version.
Restart the app after changing the setting.

Advanced Tips For Power Users

If you manage a lot of emails, these tips can streamline your workflow.

Create A Rule To Auto-Mark Urgent Emails

You can set up a rule that automatically marks incoming emails as urgent based on the sender or subject.

Go to File > Manage Rules & Alerts.
Click New Rule.
Choose Apply rule on messages I receive.
Set conditions like “from my manager” or “subject contains URGENT.”
Under actions, select mark it as high importance.
Finish the rule.

This ensures you never miss critical emails from key people.

Use Categories With Urgency

Combine urgency flags with color categories for visual cues. For example, red category for urgent, yellow for important, green for normal.

Right-click an email and choose Categorize.
Select a color or create a new category.
Name it “Urgent” and assign a red color.
Now you can quickly scan your inbox for red-categorized items.

Schedule Urgent Emails

Sometimes you need to send an urgent email but at a specific time. Use Outlook’s delay delivery feature.

Compose your email and mark it urgent.
Click the Options tab.
Click Delay Delivery.
Set the date and time you want it sent.
Click Close and send. The email stays in your outbox until the scheduled time.

This is usefull for sending urgent reminders right before a deadline.
