To see your folders, open the Navigation Pane on the left using the Show navigation pane button on the top left or by selecting View → Folder pane → Folder list → Show.
With your folders in view, you can use the arrows next to parent folders to see your subfolders.

- On iPhone, select your profile icon on the top left to open the menu.

- Long-press a folder and drag it up or down to its new spot and release.
- To turn it into a subfolder, release when you see the folder on top of another folder between the dotted lines.

How to Alphabetize Folders in Outlook
Arranging your folders in alphabetical order is not only logical, but provides you a simple way to quickly find any folder you need.
Here’s how to organize folders in Outlook for all versions:
📌 New Outlook: Select View → Folder pane → Sort folders → Order folders A to Z.
For subfolders, use the Order folders A to Z setting. Just note that this rearranges all of your folders, not just subfolders. There isn’t currently a feature to only alphabetize subfolders like in Classic Outlook.
📌 Classic Outlook: Go to the Folder tab and select Show All Folders A to Z. Note that this is only a view, it does not technically move your folders into alphabetical order. If you deselect Show All Folders A to Z, your folders return to their previous order.
For subfolders, right-click the parent folder and select Sort Subfolders A to Z.
📌 Outlook on the web: Select View → Folder pane → Sort folders → Order folders A to Z.
For subfolders, use the Order folders A to Z setting and keep in mind this alphabetizes all folders, not just subfolders.
📌 Outlook on mobile: There isn’t currently a feature to alphabetize folders or subfolders in Outlook on Android or iPhone.
Outlook Folders Out of Order?
If you have trouble after you move folders in Outlook to your chosen structure, there are a few common issues and fixes.
Synced Folder Order Changes
When you change your folder structure, Outlook syncs these changes across platforms. If you notice your folders sorting differently, you can adjust the layout between custom and alphabetical.
Additionally, when using Exchange in Classic Outlook, you may experience random changes due to cache sync loops.
To fix this, go to File → Account Settings → Account Settings and click Change for your account. Uncheck the box for Use Cached Exchange Mode and follow the prompts to restart Outlook. Rearrange your folders, return to the setting above, and check the box.
IMAP/Resync Issues
If you experience folder structure changes using IMAP, start by confirming your server settings on desktop. You can also resubscribe to the folders, reset the offline cache file, remove and re-add the account in New Outlook, or switch the Classic Outlook.
Unreliable Drag-and-Drop
Unstable drag-and-drop behavior can be caused by conflicting updates, corrupted files, or application freezes. To correct this, press the Esc key a few times, restart Windows Explorer, use Outlook in Safe Mode, or disable the Run This Program as an Administrator setting.
For a quick solution, use the right-click menu and the Move Up and Move Down options instead of drag-and-drop.
Odd Numeric Folder Sorting
If you use numbers in your folder names, keep in mind that Outlook sorts them lexicographically. This means if you label your folders in numeric order such as Folder 1, Folder 2, and so on, you’ll notice that when you get to Folder 10 and Folder 11, these will come before Folder 2.
To solve this, add padding in front of the numbers such as Folder 01 and Folder 02. Then when you get to Folder 10 and Folder 11, they’ll retain the correct numeric order.
Outlook Folder Structure Best Practices
If you struggle to create a solid folder structure, there are a few best practices that can help.
- Create a limited number of useful folders to keep the structure manageable and delete Outlook folders you no longer need.
- Consider action-based naming such as Urgent, Action, Pending, and Complete.
- Use numbering prefixes where useful to avoid odd number folder sorting as described above.
- Assign categories when folders are unnecessary rather than creating numerous folders.
With a sensible folder structure, you can also consider automatically sorting emails in Outlook as they arrive.
How to Organize Outlook Messages With Clean Email
With tools that complement the Outlook version you use, you can take advantage of features that help eliminate extra folder work.
Clean Email is available for all IMAP accounts, works on the web, Mac desktop, and mobile, and offers these features:
Smart Folders are pre-made folders that automatically filter related emails. You’ll find folders for Travel, Online Shopping, Finance, Social Notifications, and more, that help you keep Outlook organized without lifting a finger.


Auto Clean lets you create inbox rules to move Outlook emails to folders automatically. An advantage to this feature is that rules apply to both new and existing emails. This helps you clean and declutter your entire mailbox.


FAQs
Can I change the order of folders in Outlook?
Yes, you can reorder folders in New Outlook, Classic Outlook, Outlook on the web, and Outlook for iOS. The option is not currently available in Outlook for Android.
Why won't Outlook alphabetize my folders?
Outlook folders can’t be alphabetized automatically on mobile. However, you can use the Order folders A to Z settings in New Outlook and Outlook on the web or Show All Folders A to Z in Classic Outlook. You’ll find this setting in the ribbon in these versions.
How do I stop Outlook from rearranging folders?
You can disable the automatic alphabetic ordering in Outlook by choosing Custom folder order in New Outlook and Outlook on the web or deselecting the Show All Folders A to Z button in Classic Outlook. Then, rearrange your folders as you please.
Why do numbered Outlook folders sort incorrectly?
Outlook orders numbered folders lexicographically. This means that the number 10 appears before the number 2 (because 1 comes before 2.) To fix this, use number padding for single digits such as 01, 02, and so on.
Can I rearrange Outlook accounts or mailboxes?
You can rearrange the order of your accounts in Classic Outlook by dragging them to your desired order. On Android or iPhone, select Settings → Accounts → Edit and drag them to your preferred order.
