Too Many Folders, Not Enough Clarity
If you've used Outlook for a while, you've probably collected folders like souvenirs. One for receipts. Another for travel. A dozen for “important stuff” you never got around to deleting.
But here's the thing — organizing too much can be its own kind of clutter. And eventually, all those folders just make it harder to see what matters.
So, yeah — it's probably time to use some Outlook tips and tricks and clean house a bit.
How to Delete Folders in Outlook
Maintaining well-organized folders within your inbox can really help cut down on the amount of clutter you see every time you check your mail. However, these folders can also take up space or get in the way of your quest to achieve Outlook Inbox Zero. Therefore, you may want to occasionally remove folders you no longer need or ones that contain outdated information.
Like anything else, figuring out how to delete folders in Outlook can be a bit of a pain at first. Also, the version you use determines what steps you need to take to remove these folders (or if deleting folders is even possible). Therefore, we’ve broken down how to delete Outlook folders into bite-size steps based on which version you use.
⚠️ Before you delete a folder
When you delete a folder in Outlook, all the emails inside it are deleted as well and moved to Deleted Items (or Trash) for that account. If there’s anything important inside a folder, move or copy it to a different one before deletion.
Delete Outlook folders in the web app
- Open your mail account on web.
- From the folder pane on the left side, right-click the folder (or subfolder) you wish to be deleted.
- Select Delete Folder.
- Select OK to confirm this change to your inbox.


💡 Note: You cannot delete built-in folders such as Inbox, Sent, or Junk.
Delete Outlook folders in the desktop email client
- Open your mail account in the desktop application.
- From the folder pane on the left side, right-click the folder (or subfolder) you wish to remove.
- Select Delete Folder.
- You’ll receive a message asking if you want to move this folder and all of its contents to your Deleted Items folder (or Trash). Select Yes.
- To permanently remove everything, you will now need to go and empty your Deleted Items (Trash) folder. You can do this by right-clicking on the folder and choosing Empty Folder.


💡 Note: The one thing you can't do is delete Outlook's built-in folders – no way, you can't get rid of your Inbox, Sent mail, or Junk folder – they're stuck with you for good.
How to delete folders in Outlook mobile app on iPhone or Android
Good news — now you can delete folders directly in the new Outlook mobile app, and it's pretty simple once you know where to look.
Here’s how:
- Open the Outlook app and go to your Folders view.
- Tap the pencil icon (Edit).
- Find the folder you want to delete and tap on it.
- In the menu that appears, choose Delete.


📌 Note: You still can’t delete built-in system folders like Inbox, Archive, or Deleted — only the custom ones you’ve created.
💡 Note: If you don’t see an option to delete folders in the app yet, your app might not be up-to-date, or your account might not have the feature fully rolled out. In that case, try updating the app or just sign in at Outlook.com from a mobile browser, request the desktop version, and delete the folder there.
How to delete all emails in a folder in Outlook
If you have any emails in a folder you remove, these messages will also be removed from your mailbox. However, you will need to take the additional step to empty your Deleted Items (Trash) folder.


To empty the Trash or Deleted Items folder, just right-click on that folder and choose Empty Folder to clear it out. This will permanently remove all emails within the folder you deleted.


How to Delete Multiple Folders in Outlook
If you’re fairly tech-savvy, you may have already tried to use the Control key to see if you can highlight multiple folders so you can delete them all at once. Unfortunately, that’s not the way to delete multiple folders in Outlook. Instead, you’ll need to take a few extra steps.
💡 Note: These steps work with both the web and desktop apps.
- Login to your mail account.
- Create a new folder for your inbox. Be sure to name it something obvious, like “Temp” or “To Delete.” (If you aren’t sure how to do that, we have a guide that explains how to create folders in Outlook as well.)
- Once the folder is created, drag any folders you want to delete into that folder. This will make them Subfolders within that temporary folder.
- Now, right-click on that main folder you created and select Delete Folder. You’ll be prompted to confirm the action, and you will select OK (web) or Yes (desktop).
- The folders will now be deleted. However, you will need to empty your Trash or Deleted Items to remove everything permanently.
💡 Note: For very large folder structures, some power users rely on Outlook macros or third-party add-ins to bulk-remove folders, but those go beyond what most people will ever need.
Organize Your Outlook Inbox Even More with Clean Email
Although there is no option to delete custom folders outside of Outlook itself, that doesn’t mean you can’t use other tools to help you reclaim your inbox and keep it organized.
In fact, we recommend Clean Email as a useful email management tool that works across macOS, iOS, Android, and the web for anyone who wants to keep their inbox running smoothly.


Clean Email offers several tools that can save you the trouble of learning how to delete multiple emails in Outlook. For example, Smart Folders gives you easy access to messages based on specific commonalities the app identifies within your inbox.


These could be Top senders or Misc notifications. Once you open these Smart Folders, you can easily select all messages and delete or move them to a folder — whatever makes the most sense to you.
Similarly, the Unsubscriber tool lets you remove yourself from promotional mailings you don’t wish to receive or move them to a dedicated Read Later folder to keep them organized and out of your main inbox. And, since Unsubscriber works by domain, you won’t have to worry about sneaky messages slipping through the cracks.


Or, you can use Auto Clean to set up automation rules to save you time on common tasks you perform in your inbox. If you’re wondering how to automatically delete emails in Outlook or how to automatically shift certain messages into a dedicated folder, then this feature is for you.


As you can see, Clean Email can certainly help you organize your inbox even if it can’t help you remove folders in Outlook.
💡 Note: There are two versions of Outlook: the mail service provider (meaning you have an @outlook.com mailbox or similar) and the Outlook desktop client (which links with Gmail and many other mail providers). Because of the way these each work, any actions you perform in Clean Email only translate to the mail service provider, which means that they may not show up if you use the Outlook desktop client.
