How to Use Categories in New Outlook: A Quick Guide

If your Outlook inbox feels like a pile of mixed-up work, personal, and follow-up messages, categories are one of the fastest ways to bring order back.

That makes it easier to organize projects, track priorities, and find related items without digging through folders.

Whether you are cleaning up a crowded inbox or setting up a simple color system for your workflow, you will have the steps you need in just a few minutes.

Tutorial – How to Use Categories in New Outlook

These steps show you how to assign categories in New Outlook to organize messages and calendar items more efficiently. Once you set them up, categories make it much easier to scan, sort, and prioritize your Outlook data.

Step 1: Open the item you want to categorize

Open Outlook and click the email, calendar event, or task you want to label.

After you open it, you should see the message or item in its reading pane or full view, depending on your layout. Categories work on individual items, so you need to select the specific message or event first.

Step 2: Find the category option

Click Categories, the color tag icon, or the More actions menu, depending on what you are viewing.

You should now see a list of available categories. In some views, the option may appear in the top toolbar. In others, it may be hidden under a three-dot menu, especially if the window is narrow.

Step 3: Choose an existing category

Select one of the listed categories to apply it to the item.

The item should now display the category color or label. In the inbox, you may see a colored marker or the category name next to the email. That is your sign that the tag worked.

Step 4: Create a new category if needed

If the category you want does not exist, click New category or Create new, then type a name and choose a color.

After you save it, Outlook should add the new category to your list right away. You can then apply it to the current item and use it again later on other emails or calendar entries.

Step 5: Apply multiple categories when needed

Repeat the category process if you want to add multiple labels to the same item.

This is useful when one email belongs to multiple buckets, such as a project name, a priority tag, and a department tag. You will usually see more than one category shown together, which helps you sort faster without moving the message out of your inbox.

Step 6: View categorized items in your inbox or calendar

Go back to your inbox or calendar and look for the category color or label on the item.

Once categories are assigned, they act like visual sticky notes. They do not hide the item, but they make it easier to scan and group related content across your mailbox and calendar.

Step 7: Manage categories from Settings

To rename, recolor, or remove categories, open Settings and look for the Categories section.

From there, you should be able to edit the category list, change colors, or delete categories you no longer need. This is helpful if your original naming system gets messy or you want to standardize labels across work and personal items.

Alternative Methods and Edge Cases

• If you do not see Categories in the toolbar: Open the item, then click More actions or the three-dot menu. New Outlook sometimes hides features depending on window size and layout.
• If you use Outlook on the web: The steps are nearly the same. Categories usually appear in the message toolbar or under the right-click menu on an email.
• If you only want to organize one account, categories are typically tied to your Outlook profile, not just to one folder. If you use multiple accounts, check which mailbox you are in before applying labels.
• If you want to remove a category instead of creating one: Open the item, click Categories, and uncheck the category you want to remove.
• If you are using classic Outlook instead of New Outlook, the category feature is available there too, but the menu names and layout may look different. Look for Categorize or Color categories.

Frequently Asked Questions

Will categories delete my emails?

No. Categories only label items. They do not move, delete, archive, or change the content of your email.

Can I use categories on calendar events?

Yes. You can apply categories to calendar items in New Outlook, which is useful for grouping meetings by project, team, or priority.

Can I rename a category?

Yes. Go to Settings and open the Categories section. From there, you can usually rename a category and change its color.

Do categories sync across devices?

Usually, yes, if you are using the same Microsoft account. That said, appearance and exact options can vary slightly across New Outlook, Outlook on the web, and mobile apps.

Can I assign more than one category to an email?

Yes. Outlook allows multiple categories on the same item, which is helpful when one message belongs to more than one workflow.

What is the difference between categories and folders?

Folders move email into separate places. Categories leave email where it is and add a color label, so you can organize without filing everything away.

Tips

• Use a simple naming system, such as Urgent, Follow-Up, and Waiting on Reply, so your categories stay easy to understand.
• Pick a consistent color scheme. For example, red for urgent items and blue for project work. Consistency makes scanning much faster.
• Keep category names short. Short labels are easier to read in the inbox and on mobile devices.
• Use categories instead of overusing folders to see messages in one place while keeping them organized.
• If you manage many messages, combine categories with search to quickly find all items in a single project or priority level.
• Review your categories every few weeks and delete ones you no longer use. A clean list is easier to work with.

Troubleshooting

• I do not see the category option. Make sure you are using New Outlook and not a stripped-down preview or a narrow window view. Try widening the window or fully opening the item.
• My category changes did not save. Refresh Outlook, then try again. If the issue continues, sign out and back in, or check whether your account has sync delays.
• Categories look different on my phone. Mobile Outlook apps sometimes show labels differently, often with less color detail. The category may still be there even if the view is simpler.
• I cannot create a new category. Your Microsoft account or organization may limit category management. If this is a work account, ask your admin whether category editing is restricted.
• I removed a category by mistake. Reopen the item, click Categories, and add it back. If you deleted the category itself, create it again in Settings.
• The same category is missing on another device. Give sync a little time, then force a refresh or restart Outlook. If the account is managed by your workplace, some settings may not sync instantly.

Conclusion

Categories in New Outlook are a simple but powerful way to turn a messy inbox into something you can actually read at a glance. Once you know where the category tools live, you can label messages, meetings, and tasks in seconds.

The best part is that you do not have to overhaul your whole mailbox to get results. Start with a few color-coded categories, use them consistently, and Outlook becomes much easier to navigate day-to-day.
