Deleting a folder in Outlook is a straightforward process, but the steps differ slightly depending on whether you use the desktop app or the web version

In Outlook desktop (Windows or Mac), right-click the folder you want to delete, select Delete Folder from the menu, and confirm. In Outlook on the web, click the three dots next to the folder name and choose Delete. The folder and all messages inside it move to your Deleted Items folder, where they stay for 30 days before Outlook removes them permanently. You can recover a deleted folder during that window by opening Deleted Items and moving it back.

The process takes about 10 seconds. The main thing to know beforehand is that deleting a folder deletes everything in it — Outlook does not give you a second chance to save individual messages before the folder disappears from your main view.

Key Takeaways

  • Deleted folders move to Deleted Items for 30 days before permanent removal, so you can recover them if you change your mind.
  • Deleting a folder deletes all messages inside it at the same time — Outlook does not let you save individual messages first.
  • The steps are different in Outlook desktop (right-click the folder) and Outlook on the web (click the three-dot menu).
  • If you want to keep the messages but remove the folder, move them to another folder before deleting.

How to delete a folder in Outlook desktop

Open Outlook on your computer. In the left sidebar under Mail, find the folder you want to delete. Right-click on the folder name. A menu appears with several options. Click Delete Folder. Outlook asks you to confirm — click Yes to proceed.

The folder disappears from your sidebar and moves to Deleted Items. You can see it there by clicking the Deleted Items folder. If you deleted it by mistake, right-click the folder name in Deleted Items and select Move, then choose where you want it to go. This works for 30 days. After 30 days, Outlook permanently removes the folder and you cannot recover it.

How to delete a folder in Outlook on the web

Log into your Outlook account at outlook.com or outlook.office.com. In the left sidebar, find the folder you want to delete. Hover over the folder name until three dots appear on the right side. Click those three dots. A dropdown menu opens. Click Delete.

Outlook moves the folder to Deleted Items. To recover it, click Deleted Items in the sidebar, find the folder, click the three dots next to it, and select Move to. Choose the location where you want it restored. You have 30 days to do this before the folder is gone permanently.

What happens to messages when you delete a folder

Every message inside the folder moves to Deleted Items along with the folder itself. Outlook does not separate the messages from the folder — they travel together. If the folder contained 500 emails, all 500 move to Deleted Items as a group.

This is why it matters to check what is inside a folder before you delete it. If you want to keep some messages but remove the folder, move those messages to a different folder first. Then delete the now-empty folder. This takes a few extra minutes but prevents accidental loss.

How to move messages before deleting a folder

If a folder contains messages you want to keep, move them before you delete the folder. In Outlook desktop, select the messages you want to save (click one, then hold Ctrl and click others to select multiple). Right-click the selection and choose Move. Pick the destination folder from the list. Once the messages are moved, the original folder is either empty or contains only the messages you are willing to lose. Then delete the folder using the steps above.

In Outlook on the web, select the messages the same way (click one, then hold Ctrl and click others). Click the Move to button at the top of the message list. Choose the destination folder. After the messages are moved, delete the folder by clicking the three dots next to its name and selecting Delete.

Recovering a deleted folder within 30 days

Outlook keeps deleted folders in Deleted Items for 30 days. During this time, you can restore the folder and all its contents. In Outlook desktop, click Deleted Items in the left sidebar. Find the folder you deleted. Right-click it and select Move. Choose where you want the folder to go — usually back to Mail or to a specific location in your folder structure.

In Outlook on the web, click Deleted Items in the sidebar. Find the folder. Click the three dots next to it. Select Move to and choose the destination. The folder reappears in your sidebar with all its messages intact. After 30 days, Outlook permanently deletes the folder and you cannot recover it.

Differences between deleting and archiving a folder

Deleting removes a folder from view and moves it to Deleted Items. Archiving moves a folder to an archive file on your computer (desktop only) or to an archive folder in your account (web). Archiving is useful if you want to keep old messages but get them out of your main inbox view. Deleting is useful if you no longer need the folder at all.

To archive instead of delete in Outlook desktop, right-click the folder and select Archive (if available in your version). The folder moves to an archive location. To archive in Outlook on the web, you typically move the folder to an Archive folder if one exists, or you can create one. Archiving takes more steps than deleting, but it preserves the messages in case you need them later.

Frequently Asked Questions

Can I delete a folder that has subfolders inside it?

Yes. When you delete a folder, all subfolders and all messages inside them are deleted too. Outlook does not ask you to delete subfolders separately. If you want to keep a subfolder, move it to a different parent folder before deleting the main folder.

What if I deleted a folder more than 30 days ago?

Once 30 days pass, Outlook permanently removes the folder from Deleted Items and you cannot recover it. If you have a backup of your Outlook data or if your email account is synced to another device, you might be able to restore it from there. Otherwise, the folder is gone.

Does deleting a folder delete it from all my devices?

Yes, if your Outlook account is synced across devices (phone, tablet, computer), deleting a folder on one device deletes it on all of them. The deletion syncs within a few minutes. If you use Outlook offline on one device, the deletion may not sync until you connect to the internet.

Can I delete a system folder like Inbox or Sent Items?

No. Outlook does not let you delete system folders — Inbox, Sent Items, Drafts, Deleted Items, and Junk Email are permanent. You can create custom folders and delete those, but the main system folders stay in your account.

How do I delete multiple folders at once?

In Outlook desktop, you can select multiple folders by holding Ctrl and clicking each one, then right-clicking and selecting Delete Folder. In Outlook on the web, you typically delete one folder at a time using the three-dot menu. Some versions may allow multiple selection, but the web version is usually one at a time.
