Outlook can show folders in more than one “order,” and not all orders are editable. What you can change depends on your Outlook version, your account type (Exchange/Microsoft 365, IMAP, POP), and whether you’re using the classic desktop app or the newer web-style client.
This guide focuses on the practical goal: getting the folders you use most to appear first—either by true manual reordering (when supported) or by using Favorites/quick access and other reliable workarounds.

What reordering folders in Outlook really means
When people say “reorder folders in Outlook,” they usually mean one (or more) of these:
- Manual position in the navigation pane (drag a folder up/down so it stays there).
- Favorites order (pin folders to Favorites so they appear at the top in a sequence you control).
- Sort order (alphabetical, date, or server-defined order). Sorting may override manual placement.
Depending on your mailbox and Outlook client, “manual position” might be allowed for Favorites but not for the main folder tree.
#1 Best Overall
Which Outlook version are you using?
The fastest way to avoid frustration is to confirm your client first. Reordering options differ between classic Outlook, Outlook for Mac, and Outlook on the web.
| Client | Typical reordering behavior | What to do instead if manual order isn’t available |
|---|---|---|
| Outlook for Windows (classic) | Favorites order is usually controllable; main folder tree depends on account/server | Use Favorites/Quick Access; ensure folder pane isn’t set to auto-sort |
| Outlook for Mac | Favorites/quick access is more reliable than deep custom ordering | Use Favorites; use rules/categories to reduce navigation |
| Outlook on the web | Often limited; many tenants keep folder order server-defined | Use Favorites/pinned folders; rely on Search |
Reorder folders in Outlook for Windows (classic Outlook)
If you’re on the classic desktop app, you usually have the best chance of changing what you see. Start with Favorites if you just want your most-used folders at the top.
Use Favorites (the order you control)
Favorites is the most dependable way to control order because it’s a UI-level list, not the server’s folder tree order.

- In the left navigation pane, find the folder you want to move.
- If it isn’t in Favorites, right-click the folder and choose Add to Favorites.
- With the folder in Favorites, drag it up or down to the position you want.
- Repeat for other folders until the top of Favorites matches your workflow.
If you don’t see “Favorites,” enable it: go to the View tab, then confirm the Folder Pane settings show a Favorites section.
Drag folders within the folder list (when supported)
Some folder trees (especially when supported by the server and account type) allow drag-and-drop within the same parent.
- In Outlook, ensure you’re viewing the Mail navigation pane.
- Click and hold the folder name under the same parent folder.
- Drag it up/down to the new position until you see a placement indicator.
- Release the mouse button to drop it.
If the folder won’t move, snaps back, or reverts after reopening Outlook, that’s typically a sign your mailbox/server enforces a fixed order.
Sort controls vs manual order
Outlook has views that can appear “sorted” even when you try to place folders manually. Check that you’re not relying on a sorted view that overrides the display order.
Recommended Free Tools
- Look for any sorting options in the folder pane area (varies by Outlook build).
- If you used a toggle like “Sort by” for folders and it’s enabled, try turning it off or switching back to the default manual behavior.
When in doubt, Favorites is the safe path because it’s explicitly designed for user-controlled navigation.
Reorder folders in Outlook for Mac
Outlook for Mac supports a more limited set of folder-order controls compared to Windows classic. In practice, Favorites/quick access delivers the most consistent results.
Use Favorites/quick access
- Open Outlook on your Mac.
- In the left sidebar, locate the folder you want to promote.
- Right-click the folder and choose Add to Favorites (wording may vary slightly).
- Drag the folder within the Favorites area to change its position.
If you can’t drag, use the nearest available reordering action in the Favorites list—some macOS builds focus more on adding/removing than deep sorting.
Reordering the main folder list
For the main folder tree, Mac may defer to the server-defined structure. If you try to drag folders and the order doesn’t persist, don’t fight it—use Favorites and/or shortcuts.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minuteA quick test: after you reorder, close Outlook completely and reopen it. If the order resets, the reordering isn’t being saved by your account/server combination.
Reorder folders in Outlook on the web
Outlook on the web is commonly more restrictive. Many tenants keep mail folder order consistent with the server folder tree, which means you can’t always rearrange it manually.
Use Favorites or folder shortcuts instead of ordering
- Go to Outlook on the web and sign in (for example: https://outlook.office.com for Microsoft 365).
- In the folder list on the left, find your target folder.
- Choose Add to Favorites (or the equivalent pin option) if available.
- Reorder only within the Favorites area if the UI provides up/down controls or drag support.
When the UI doesn’t offer any reordering control, pinned Favorites is the correct workaround.

When folder order is fixed by the server
For Exchange and many Microsoft 365 setups, folder order may be defined by server-side folder hierarchy rules. In those cases, Outlook clients can display the same structure everywhere—even if you can’t change positions.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
That’s why Favorites/Quick Access tends to be the reliable “user-controlled order” across devices.
Accounts that behave differently (Exchange vs IMAP vs POP)
Account type strongly affects whether manual folder reordering will persist.
- Microsoft 365 / Exchange: Favorites ordering is usually supported; the main folder tree may be server-defined.
- IMAP: Some IMAP servers represent folders in a way that discourages or prevents client-side reordering. Favorites still tends to work.
- POP: Folder structure is limited because POP primarily fetches mail; folder reordering may be irrelevant or unsupported depending on how you’re using it.
If your account is managed by an organization, admin policies can also restrict what Outlook allows you to do in the navigation pane.
Step-by-step: make your folders appear in the order you want
Here’s a workflow that works regardless of client quirks: build a Favorites list that reflects your priorities, then keep your main tree as-is.
Scenario 1: You want Inbox subfolders grouped first
- Under Inbox, identify the subfolders you use daily.
- For each one, right-click and select Add to Favorites (if needed).
- Drag those Favorites items to the top of Favorites in the exact order you want.
This creates a consistent “Inbox-first” view without depending on whether Outlook can reorder the underlying server folder tree.
Scenario 2: You want a few folders always at the top
- In Outlook, choose the 5–10 folders you touch most (for example: Client Updates, Invoices, Receipts, Completed).
- Add them to Favorites.
- Reorder within Favorites by dragging (Windows/classic) or using any available ordering control (Mac/web when supported).
If a folder won’t stay in its position, confirm you’re reordering inside Favorites—not the main folder tree.
Scenario 3: You want alphabetical order restored
If your folder list got messy and you want order again, prefer reset-over-repair.
- Remove folders from Favorites temporarily (right-click > Remove from Favorites).
- Re-add folders in batches and place them using drag order.
- If your client supports folder pane sorting, enable Sort A to Z (wording varies) and then re-check Favorites ordering.
For server-defined trees, you may never get a perfect “A to Z” across all clients—but Favorites lets you approximate it quickly.

If reordering fails, don’t assume you’re doing it wrong. The most common causes are server restrictions, UI version differences, and sync state.
Drag-and-drop doesn’t move anything
- Try reordering inside Favorites instead of the main folder tree.
- Confirm you’re in the classic desktop app (Windows) and not the new Outlook client.
- Check whether the folder is under a different mailbox/account than you expect.
The folder snaps back to the old position
- That typically means the server rejected the new order. Use Favorites as the controlling list.
- Make sure you’re dragging within the same parent folder (moving across parents may be blocked).
After restart, the order resets
- Wait for sync to finish, then reorder again.
- On Windows, consider forcing a mail resync by restarting Outlook.
- Reorder again in Favorites, not the main tree.
Reordering works on one device but not another
- Your Favorites settings may not be synchronized the way you expect.
- Different clients may interpret ordering controls differently (Windows classic vs Mac vs web).
- For server-fixed folder trees, only the Favorites list will look “user-ordered.”
Outlook is offline or stuck syncing
- On Windows, check Send/Receive status.
- Reconnect to the internet if you’re using a VPN or have intermittent connectivity.
- After sync completes, try reordering again.
Common mistakes to avoid
- Reordering the wrong place: trying to change the main folder tree when Favorites is what’s editable.
- Changing parents: dragging a folder to a different parent can be blocked or revert.
- Assuming it’s persistent: always test by closing and reopening Outlook.
- Mixing clients: don’t expect the same ordering behavior on Outlook on the web if your tenant enforces server order.
Alternatives if you can’t reorder folders
If Outlook won’t let you change the navigation structure, you still have good options to keep your workflow fast.
Pin folders to Favorites
This is the closest thing to a reliable “custom folder order” across devices. Add the folders you care about, then arrange them in Favorites.
Use Search and Search folders
Search folders (or saved searches, depending on client) help you jump to what you need without relying on folder placement.
- Search for the sender, subject, or tag you use most.
- Create a saved search for a recurring workflow (invoices, receipts, approvals).
Use Rules + Categories to keep navigation clean
Even if your folders remain unordered, you can reduce how often you navigate between them. Use Rules to file mail automatically into the right folders and apply Categories so triage takes seconds.
FAQs
Can I reorder folders in the main folder list in Outlook on Microsoft 365?
Sometimes, but not consistently. Many Exchange tenants treat main folder order as server-defined. Favorites is usually the reliable way to control what appears first.
Why can I reorder Favorites on Windows but not on Outlook on the web?
Because the web client often restricts drag-and-drop or the UI doesn’t expose reordering controls. Use pinned Favorites where available, and keep your “ordered list” in the client that supports it most.
Will folder order changes sync to my other devices?
Favorites changes may sync depending on your account and client. Main folder tree order changes generally don’t behave like a per-user setting when the server controls ordering.
The Tool Desk
Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →What if my account is IMAP and none of this works?
IMAP servers vary. If drag-and-drop won’t persist, switch to a Favorites/quick access approach and use search to navigate quickly. If needed, consider consolidating messages with filters or rules.
Bottom Line
To reorder folders in Outlook, focus on the layer you can control: Favorites/quick access. Manual folder-tree reordering may be blocked or reset by server rules, especially on Exchange/Microsoft 365 and many web clients.
If drag-and-drop won’t stick, don’t waste time troubleshooting endless UI behavior—pin your important folders, then use search and rules to make folder navigation fast.
