How to Delete a Folder in Outlook (And What Happens When You Do)

Deleting a folder in Outlook is straightforward on the surface — a few clicks and it's gone. But depending on which version of Outlook you're using, what type of folder it is, and whether you're on desktop, web, or mobile, the behavior changes in ways that matter. Here's what you need to know before you delete anything.

The Basics: How Folder Deletion Works in Outlook

When you delete a folder in Outlook, two things happen simultaneously:

1. The folder itself is removed from your folder panel.
2. All emails inside the folder are moved to the Deleted Items folder — not permanently erased immediately.

This is important. Outlook treats folder deletion as a soft delete by default. You have a recovery window before anything is truly gone. That recovery window depends on your account type and settings — more on that below.

How to Delete a Folder in Outlook Desktop (Windows & Mac)

The process is nearly identical across Outlook for Windows and Outlook for Mac.

Steps:

1. Open Outlook and locate the folder in the left-hand sidebar.
2. Right-click the folder you want to delete.
3. Select "Delete Folder" from the context menu.
4. A confirmation dialog will appear — click Yes to confirm.

The folder disappears from your sidebar, and its contents land in Deleted Items.

🗂️ Note: You cannot delete default system folders — Inbox, Sent Items, Drafts, Outbox, Junk Email, and Deleted Items are locked. Right-clicking these folders won't show a delete option.

Keyboard Shortcut Option

If you prefer not to right-click, you can:

• Click the folder to select it
• Press the Delete key on your keyboard
• Confirm when prompted

How to Delete a Folder in Outlook on the Web (OWA)

Outlook on the Web — accessed through Outlook.com or your organization's Microsoft 365 portal — works slightly differently.

Steps:

1. In the left sidebar, hover over or right-click the folder you want to remove.
2. Select "Delete folder" from the dropdown menu.
3. Confirm the deletion.

Again, the folder's contents move to Deleted Items. The interface is cleaner than the desktop app but the underlying behavior is the same.

How to Delete a Folder in the Outlook Mobile App

On iOS and Android, the Outlook mobile app handles folder management through a slightly buried menu.

Steps:

1. Tap the hamburger menu (☰) in the top-left corner to open the folder panel.
2. Tap "Edit" (iOS) or the pencil icon (Android) near the top of the folder list.
3. Tap the folder you want to delete.
4. Select "Delete" and confirm.

Mobile Outlook gives you fewer options at a glance, so editing mode is where folder management lives.

What Happens to the Deleted Emails?

This is where account type creates real differences.

Microsoft 365 and Exchange accounts often have additional layers — including a Recoverable Items folder that admins may control — which means even "deleted" emails can sometimes be recovered by an IT department long after you thought they were gone.

How to Permanently Delete a Folder and Its Contents

If you want the folder and its contents gone from Deleted Items as well:

1. Go to your Deleted Items folder after deleting the original folder.
2. Find the folder inside Deleted Items (yes, it appears as a sub-folder there).
3. Right-click it and select "Delete Folder" again.
4. Confirm — this time it's a permanent deletion (or moves to Recoverable Items on Exchange).

Alternatively, you can right-click Deleted Items and choose "Empty Folder" to clear everything at once — but this removes all deleted items, not just the folder you targeted.

Folders You Cannot Delete

Certain folders are protected by Outlook regardless of version:

• Inbox
• Sent Items
• Drafts
• Outbox
• Junk Email
• Deleted Items
• Archive (on some account configurations)

Any custom folder you created — or folders created by third-party plugins and rules — are generally deletable. If you're unable to delete a folder, it's worth checking whether it was created by a connected app or an Outlook rule, since those can sometimes lock folder structures.

🔄 Can You Recover a Deleted Folder?

Yes, within limits. If you deleted a folder accidentally:

1. Go to Deleted Items.
2. Find the folder.
3. Right-click and select "Move" or "Restore" to put it back where it was.

On Microsoft 365 accounts, if the folder has already been purged from Deleted Items, you may be able to recover it through Recover Deleted Items (found under the Folder tab in the desktop app or via the web interface) — this taps into the Recoverable Items cache.

How long that cache holds your data depends on your organization's retention policies or your personal account settings, which vary widely from one setup to the next.
