Creating a folder takes three clicks

To create a new folder in Outlook, right-click on "Inbox" or any existing folder in the left sidebar, select "New Folder", type a name, and press Enter. The folder appears when ready below the one you right-clicked on. You can then drag emails into it or set up rules to move messages there automatically.

The process is the same whether you use Outlook on Windows, Mac, or the web version. The folder exists only on your device or account — it does not sync to other programs unless you export it.

Key Takeaways

  • Right-click any folder in the left sidebar and select "New Folder" to create a folder in seconds.
  • Name your folders by sender, topic, or project so you can find emails later without searching.
  • You can create folders inside other folders to organize by category and subcategory.
  • Outlook rules can move incoming emails to folders automatically based on sender, subject line, or keywords.

Where to find the New Folder option

Open Outlook and look at the left sidebar where you see "Inbox", "Sent Items", and "Deleted Items". Right-click directly on any of these folder names. A small menu appears with several options — one of them says "New Folder".

If you are using Outlook on the web (Outlook.com or your work account in a browser), the process is slightly different: click the plus sign next to "Folders" at the top of the left sidebar, then type the folder name and press Enter.

Naming your folder so you can find it later

After you click "New Folder", a text box appears asking you to name it. Type something specific that describes what goes inside — not "Stuff" or "Files", but "Apartment Lease", "Tax Documents 2024", or "Client: Johnson Project". The more specific the name, the faster you can spot the folder when you are scanning your list.

Use the same naming pattern for all your folders so your brain learns where to look. If you create folders for people, start each name with the person's first name. If you create folders for topics, start with the topic. This keeps related folders grouped together alphabetically.

Creating folders inside folders

You can organize folders into groups by creating a folder inside another folder. Right-click the parent folder (the one you want to put a new folder inside), select "New Folder", and name it. The new folder nests underneath and appears indented in your sidebar.

For example, you might create a "Finances" folder, then create "Taxes", "Insurance", and "Receipts" folders inside it. This keeps your sidebar from becoming a long list that is hard to scan. Limit yourself to two levels deep — a folder inside a folder inside a folder becomes harder to navigate than it is worth.

Moving emails into your new folder

Once your folder exists, drag an email from your inbox and drop it on the folder name. The email moves when ready. You can also right-click an email, select "Move", and choose the folder from the list that appears.

To move multiple emails at once, click the first one, hold Ctrl (or Cmd on Mac), and click the others to select them all. Then drag them together to the folder, or right-click and select "Move".

Setting up automatic rules to sort incoming mail

Instead of moving emails by hand every time, you can tell Outlook to move certain messages automatically. Right-click an email from a sender you want to organize, select "Rules", and choose "Always Move Messages From [Sender Name]". A dialog appears asking which folder to move them to — select your new folder and click "OK".

You can also create more complex rules. Click the "File" menu (or the gear icon on the web), select "Manage Rules & Alerts", and click "New Rule". You can then set conditions like "if the subject contains [word]" or "if it comes from [email address]" and tell Outlook to move those messages to your folder automatically. This keeps your inbox clean without any work on your part.

Deleting or renaming a folder you no longer need

Right-click the folder name and select "Delete Folder". Outlook asks you to confirm — click "Yes". Any emails inside the folder move to your Deleted Items folder, where you can recover them for 30 days before they are permanently removed.

To rename a folder instead of deleting it, right-click the folder name and select "Rename Folder". Type the new name and press Enter. This is useful when your needs change — "Client: Johnson Project" becomes "Completed: Johnson Project" once the work is done.

Frequently Asked Questions

Can I create a folder on my computer that Outlook reads automatically?

No. Outlook folders exist only inside Outlook. If you create a folder on your desktop or in File Explorer, Outlook will not see it or move emails there. You must create folders through Outlook itself using the right-click method described above.

What happens to emails if I delete a folder?

The emails move to your Deleted Items folder, not permanently erased. You have about 30 days to recover them by opening Deleted Items, finding the emails, right-clicking them, and selecting "Move" to put them back in another folder.

Can I move a folder I created into a different folder?

Yes. Right-click the folder you want to move, select "Move Folder", and choose the destination folder from the list. The folder and all its emails move together to the new location.

Do folders I create in Outlook sync to my phone?

If you use the official Outlook app on your phone and sign in with the same account, your folders appear on the phone too. If you use a different email app like Gmail or Apple Mail, the folders may not show up — check your app's settings to see if it supports custom folders.

How many folders can I create?

Outlook does not have a practical limit on the number of folders you can create. However, more than 50 or 60 folders becomes hard to navigate. Instead, use subfolders to keep your sidebar organized and readable.
