How To Make Email High Priority In Outlook

Flagging an email as high priority in Outlook changes its appearance and delivery behavior. This article shows you exactly how to make email high priority in outlook using simple steps. Whether you use Outlook desktop, web, or mobile, you can mark urgent messages so recipients notice them faster. Let’s get straight into it.

Setting a high priority flag tells the recipient your message needs immediate attention. In Outlook, this adds a red exclamation mark and may adjust how the email is displayed. Follow these methods for different versions of Outlook.

Using Outlook Desktop (Microsoft 365 And Outlook 2019/2021)

Open Outlook on your computer. Start composing a new email or reply to an existing one. Look for the toolbar at the top of the message window.

Click the “Message” tab in the ribbon menu.
Find the “Tags” group. It usually contains options like “Follow Up” and “High Importance.”
Click the “High Importance” button. It looks like a red exclamation mark.
You will see a red bar appear at the top of the email. This confirms high priority is set.
Complete your email and send it as usual.

Thats all it takes. The recipient will see the red exclamation mark in their inbox. If they use Outlook, the email may also show a priority banner.

Using Outlook On The Web (Outlook.com Or Office 365 Web)

The web version of Outlook works slightly differently. Here is how to mark an email as high priority online.

Log in to your Outlook web account.
Click “New message” to start composing.
In the compose window, look for the three-dot menu (More options) in the toolbar.
Click it, then select “High importance” from the dropdown list.
A red exclamation mark will appear next to the subject line.
Write your message and hit send.

Some users miss this option because it is hidden under the menu. Keep an eye out for the three dots. This method works for both personal and business accounts.

Using Outlook Mobile App (IOS And Android)

Marking an email as high priority on your phone is just as easy. The steps are similar for both platforms.

Open the Outlook app on your phone or tablet.
Tap the compose button (pencil icon) in the bottom right corner.
In the compose screen, tap the three-dot menu (More options) at the top right.
Select “High importance” from the menu. A red exclamation mark appears.
Fill in the recipient, subject, and message.
Tap the send button.

On mobile, the high priority setting is not always visible by default. You need to expand the options menu. Once set, the recipient sees the red flag in their inbox.

Setting High Priority For Multiple Recipients Or Distribution Lists

When you send an email to a group, you can still mark it as high priority. The process is the same as for individual recipients. However, be careful not to overuse this feature. Sending too many high priority emails can desensitize your audience.

Use high priority only for truly urgent matters.
Avoid marking routine updates as high priority.
Consider using a separate subject line like “URGENT” if needed.

Outlook does not limit how many high priority emails you can send. But your recipients might start ignoring the flag if you use it too often.

How To Check If Your Email Is Marked As High Priority

Before sending, verify that the high priority flag is active. Look for these indicators:

In the desktop version, a red bar appears at the top of the email.
In the web version, a red exclamation mark shows next to the subject.
In the mobile app, the same red exclamation mark appears in the compose screen.

If you do not see any of these, the email is set to normal priority. Double-check before hitting send.

What Happens When You Send A High Priority Email

Outlook changes the appearance and delivery behavior of high priority emails. Here is what recipients experience:

The email shows a red exclamation mark in their inbox list.
In Outlook desktop, the email may appear with a red banner or highlight.
Some email clients (like Gmail or Yahoo) may ignore the priority flag entirely.
Outlook may also show a notification or alert when the email arrives.

Keep in mind that not all email programs respect Outlook’s priority settings. If you send to a non-Outlook user, they might not see any special marking. In that case, consider adding a note in the subject line.

How To Remove High Priority From An Email

If you accidentally set high priority, you can remove it easily. Here is how:

In the desktop version, click the “High Importance” button again to toggle it off.
In the web version, go to the three-dot menu and deselect “High importance.”
In the mobile app, tap the three-dot menu and uncheck “High importance.”

The red exclamation mark will disappear. The email will revert to normal priority. You can do this at any time before sending.

Using High Priority With Outlook Rules And Automation

You can also set up rules to automatically mark certain emails as high priority. For example, you might want all emails from your boss to be flagged. Here is a basic method:

Go to “File” > “Manage Rules & Alerts” in Outlook desktop.
Click “New Rule.”
Select “Apply rule on messages I send.”
Choose conditions like “from a specific person” or “with specific words in the subject.”
Under actions, check “assign it to the importance” and choose “high.”
Finish the rule and save.

This automation saves time. But test it first to ensure it works correctly. You dont want to accidentally mark all your emails as high priority.

Common Mistakes When Using High Priority

Many users misuse the high priority feature. Here are pitfalls to avoid:

Marking every email as high priority. This reduces the flag’s effectiveness.
Using high priority for non-urgent requests like meeting reminders.
Forgetting to remove the flag after composing the email.
Assuming all email clients display the flag the same way.

Be selective. Only use high priority when the message truly requires immediate action. Your colleagues will appreciate it.

How To Make Email High Priority In Outlook For Mac

Outlook for Mac has a similar process. Here are the steps:

Open Outlook for Mac and start a new email.
In the compose window, click the “Options” tab.
Find the “Priority” dropdown menu.
Select “High” from the list.
The email will show a red exclamation mark.
Send the email as usual.

Mac users sometimes struggle to find the option. It is not in the main toolbar by default. Look under the “Options” tab for the priority setting.

How To Set High Priority In Outlook For Multiple Emails

If you need to send several high priority emails, you can create a template. Here is a quick method:

Save it as a template (File > Save As > Outlook Template).
When you need to send a high priority email, open the template.
Edit the recipient and content, then send.

This saves time if you frequently send urgent messages. You can also use Quick Parts or signatures to automate the priority setting.

What To Do If High Priority Is Not Working

Sometimes the high priority flag does not appear to work. Here are common fixes:

Check if the recipient uses Outlook. Other email clients may ignore the flag.
Verify that you actually clicked the high importance button. It is easy to miss.
Update your Outlook version. Older versions may have bugs.
Try sending a test email to yourself to confirm the flag appears.

If the problem persists, check your Outlook settings. Go to “File” > “Options” > “Mail” and look for priority settings. Make sure nothing is overriding your choice.

Using High Priority With Outlook Categories

You can combine high priority with color categories for better organization. For example, assign a red category to high priority emails. This adds a visual cue beyond the exclamation mark.

Right-click the email in your inbox.
Select “Categorize” and choose a color.
You can also set rules to automatically categorize high priority emails.

This helps you quickly spot urgent messages in a crowded inbox.
