How To View Categories In Outlook

Categories in Outlook color-code your emails, appointments, and tasks for quick visual sorting. If you have ever wondered how to view categories in Outlook, you are in the right place. This guide will show you every method to see and manage your categories across Outlook desktop, web, and mobile versions.

Categories help you stay organized. You can assign a color to a project, a client, or a priority level. But if you cannot see them, they are not useful. Let us fix that right now.

Viewing categories is simple once you know where to look. The exact steps depend on which version of Outlook you use. Below, we break it down for each platform.

View Categories In Outlook Desktop (Windows)

Outlook for Windows gives you the most control over categories. Here is how to see them:

Open Outlook on your Windows computer.
Go to the Home tab at the top of the window.
Look for the Categorize button in the Tags group. It looks like a colored folder icon.
Click Categorize. A drop-down list appears showing all your categories.
If you see no categories, click All Categories at the bottom of the list.

The All Categories window shows every category you have created. You can also see which items are tagged with each color.

Another way to view categories is directly in your inbox. By default, Outlook shows category colors as a small colored bar on the left side of each email. If you do not see this bar, you may need to adjust your view settings.

Click the View tab.
Select View Settings.
Click Conditional Formatting.
Ensure the category rule is enabled.

You can also add the Categories column to your inbox. Right-click the column header row (where it says From, Subject, Received). Choose Field Chooser. Drag Categories into the column headers. Now you see the category name for every email.

View Categories In Outlook On The Web

Outlook on the web (OWA) works differently. Here is how to view categories in your browser:

Log in to Outlook.com or your work email web app.
Open any email message.
Look at the top of the reading pane. You will see the category color next to the subject line.
To see all categories, click the Settings gear icon in the top right.
Select View all Outlook settings at the bottom.
Go to Mail > Categories.

This page shows your full category list. You can rename, delete, or change colors here. If you want to see categories in your inbox list, enable the category column. Click the View menu in the inbox. Choose Show columns and check Categories.

One common issue: categories may not appear in the inbox list by default. You have to manually add the column. Once added, you see the category name in plain text next to each message.

View Categories In Outlook For Mac

Outlook for Mac has a slightly different interface. Follow these steps:

Open Outlook on your Mac.
Select an email, calendar event, or task.
Click the Categorize button in the toolbar. It looks like a tag icon.
A drop-down shows your current categories. Click Edit Categories to see the full list.

You can also view categories in the message list. Go to View > Columns > Categories. This adds a column that shows the category name for each item.

If you use the Mac version for work, categories sync with your Exchange account. Any changes you make appear on other devices too.

View Categories In Outlook Mobile (IOS And Android)

The mobile app is more limited. But you can still view categories:

Open the Outlook app on your phone.
Tap an email to open it.
Look at the top of the email. The category color appears as a small dot or bar.
To see all categories, tap the three-dot menu (More) in the top right.
Select Categorize. You see your category list here.

On mobile, you cannot add a categories column to the inbox view. The only way to see categories is by opening each email. This is a known limitation. However, you can filter by category using the search bar. Type “category:red” or “category:project” to find tagged items.

Common Problems When Viewing Categories

Sometimes categories do not show up as expected. Here are fixes for the most common issues.

Categories Not Appearing In Inbox

If you assigned a category but see no color, check these things:

Make sure you saved the category assignment. Click away from the email after categorizing.
Verify the category exists. Go to Categorize > All Categories to see if it is there.
Check your view settings. The category column might be hidden.
Restart Outlook. Sometimes the display refreshes only after a restart.

Categories Missing From The List

If your categories disappeared entirely, they may have been deleted or corrupted. Try this:

Go to Categorize > All Categories.
Click Reset to restore default categories.
If that fails, create new categories manually.

Categories are stored in your mailbox. If you use Exchange or Office 365, they sync across devices. A server issue can cause them to vanish temporarily. Wait a few minutes and check again.

Category Colors Not Showing In Calendar

Calendar items use categories too. But the color may not appear on the calendar grid. To fix this:

Open the calendar event.
Assign a category from the Categorize button.
Close the event. The color should now show on the calendar.

If it still does not show, change your calendar view. Go to View > Change View > Calendar. Make sure you are not using a custom view that hides categories.

How To Create And Manage Categories

Viewing categories is easier when you have them set up properly. Here is a quick refresher on managing them.

Create A New Category

Click Categorize > All Categories.
Click New.
Type a name for the category.
Choose a color from the drop-down.
Click OK.

You can also create categories on the fly. Right-click an email, select Categorize, then New Category.

Rename Or Delete Categories

In the All Categories window, select a category. Click Rename or Delete. Deleting a category removes it from all items. Those items become uncategorized.

Be careful with deletion. If you delete a category used by many emails, you lose the color coding. There is no undo for this action.

Assign Categories To Multiple Items

To categorize several emails at once:

Hold Ctrl and click each email you want to tag.
Click Categorize and choose the category.
All selected items get the same category.

This works for tasks and calendar events too. It saves time when organizing a large inbox.

Using Categories For Better Organization

Categories are not just for show. They help you filter and find items faster.

Filter By Category

In the inbox, click the Filter button. Select Category. Pick the color you want. Outlook shows only items with that category.

You can also use search. Type “category:red” or “category:project name” in the search bar. This works on desktop and web.

Create Search Folders By Category

Search folders automatically group emails by category. Here is how:

Go to Folder > New Search Folder.
Scroll down to Categorized mail.
Choose the category you want.
Click OK.

Now you have a folder that shows only emails with that category. It updates automatically as you categorize new messages.

Color-Code Your Calendar

Use categories to color-code calendar events. Assign a category to each event type. For example:

Red for meetings
Blue for deadlines
Green for personal events

Your calendar becomes a visual map of your week. You can see at a glance what kind of events you have.

Advanced Tips For Viewing Categories

Once you master the basics, try these advanced tricks.

Use Quick Steps To Auto-Categorize

Quick Steps let you apply categories with one click. Set one up:

Go to Home > Quick Steps > New.
Name the step, like “Categorize as Project.”
Choose Categorize and pick the category.
Click Finish.

Now when you hover over an email, the Quick Step appears. One click categorizes it.

View Categories In Shared Mailboxes

If you use a shared mailbox, categories work the same way. However, categories are personal. They do not sync across users. Each person sees their own categories on shared items.

To view categories in a shared mailbox, open it in your Outlook profile. The Categorize button is available there too.

Export Category Data

You cannot export categories directly. But you can export emails with category information. Use the File > Open & Export > Import/Export option. Choose “Export to a file” and select CSV. The CSV includes a column for categories.

This is useful for reporting or backup. You can see which emails have which categories in a spreadsheet.

Troubleshooting Category View Issues

Even with the right steps, things can go wrong. Here are solutions for stubborn problems.

Category Column Shows Blank

If you added the Categories column but it shows nothing, the column might be too narrow. Widen it by dragging the column border. Also, check that you actually assigned categories to items. Uncategorized items show blank.

Colors Look Different On Mobile

Outlook mobile uses a limited color palette. Some desktop colors may appear different on your phone. This is normal. The category name is still correct even if the shade varies.

Categories Not Syncing Between Devices

If you create a category on your desktop but it does not show on your phone, wait a few minutes. Sync can take time. If it still does not appear, force a sync:

On desktop: Click Send/Receive > Update Folder.
On mobile: Pull down to refresh your inbox.

If syncing fails, check your internet connection. Categories require a server connection to sync.
