How to Delete an Outlook Account: What You Need to Know Before You Start

Deleting an Outlook account isn't always a single-step process — and for good reason. Microsoft has built Outlook into a web of interconnected services, so what you're actually deleting depends heavily on which account you're working with and how you're using it. Understanding the difference before you take action can save you from accidentally losing data you didn't mean to lose.

What "Deleting an Outlook Account" Actually Means

There are two very different things people mean when they say they want to delete an Outlook account:

  1. Removing Outlook from a device or app — signing out or disconnecting an email account from the Outlook app (on Windows, Mac, iOS, or Android) without deleting the account itself.
  2. Permanently closing the Microsoft account — deleting the underlying Microsoft account, which also removes the Outlook.com email address, OneDrive storage, Microsoft 365 access, and any other tied services.

These are not the same action, and the consequences are very different. Most people who ask this question want one or the other — but not always the one they think.

Option 1: Remove an Email Account from the Outlook App 📧

If you want to stop using a specific email address inside the Outlook app — without deleting that address entirely — you're removing the account from the app, not from Microsoft's servers.

On Windows (Outlook desktop app):

  • Go to File → Account Settings → Account Settings
  • Select the account you want to remove
  • Click Remove
  • Confirm the action

On Mac (Outlook for Mac):

  • Go to Tools → Accounts
  • Select the account and click the minus (–) button

On iOS or Android (Outlook mobile app):

  • Tap the profile icon → tap the account email → scroll to Delete Account

In all of these cases, the email address still exists. You can add it back later or access it through a browser at Outlook.com. No emails are permanently deleted by this step.

Option 2: Close Your Microsoft Account Permanently ⚠️

This is the more serious action. Closing your Microsoft account deletes your Outlook.com email address, all emails in that inbox, your OneDrive files, Xbox profile, Microsoft Store purchases, and any other data tied to that account.

Before closing a Microsoft account, Microsoft requires you to:

  • Download or transfer any data you want to keep (emails, OneDrive files, contacts)
  • Cancel any active subscriptions (Microsoft 365, Xbox Game Pass, etc.)
  • Spend or transfer any remaining Microsoft Store balance
  • Review connected apps and services that use that account for sign-in

The closure process:

  1. Sign in at account.microsoft.com
  2. Go to Your Info → Account Security (or navigate directly to the account closure page under Account → Close your account)
  3. Microsoft walks you through a checklist before allowing closure
  4. After completing the checklist, you select a reason and confirm
  5. Microsoft holds the account in a 60-day grace period — during which you can reopen it — before permanently deleting it

This grace period is intentional. Microsoft treats permanent deletion as irreversible, and the 60-day window is your safety net.

Option 3: Delete a Work or School Account

If your Outlook email ends in a company domain (like [email protected]) or a school domain, it's almost certainly a Microsoft 365 business or education account — not a personal Microsoft account.

You generally cannot delete these yourself. That requires action from your organization's IT administrator. What you can do is remove it from your personal devices through the Outlook app settings, but the account itself lives on Microsoft's servers under your organization's control.

Key Variables That Change Your Approach

SituationWhat to Do
Want to stop using Outlook on one deviceRemove account from the app only
Switching to a different email providerForward emails first, then close or disconnect
Have a work/school accountContact IT admin — you can't close it yourself
Have Microsoft 365, OneDrive, or Xbox linkedCancel subscriptions before closing
Want to keep the email but clear the appRemove from app; account stays intact
Want full permanent deletionUse account.microsoft.com closure process

What Gets Lost — and What Doesn't

When you remove an account from the app, nothing in the cloud is affected. Your emails, contacts, and calendar events remain on Microsoft's servers. You just won't see them in that app installation anymore.

When you close a Microsoft account, the losses are real and — after the grace period — permanent:

  • All emails in your Outlook.com inbox
  • Contacts and calendar data synced to that account
  • OneDrive files not backed up elsewhere
  • Microsoft Store app purchases and licenses
  • Any saved passwords or passkeys tied to that Microsoft account

Third-party logins are also a factor. If you've used "Sign in with Microsoft" on other websites or services, those connections break when the account closes. It's worth auditing which services use your Microsoft account for authentication before proceeding.

The Part That Depends on Your Setup 🔍

Whether removing the account from an app is enough — or whether full account closure is necessary — comes down to factors specific to your situation: whether you've linked other services to that Microsoft account, whether you have active subscriptions, how you use OneDrive, and whether anyone else in a family group is sharing your Microsoft 365 plan.

The steps above cover what's technically possible. How far to take them, and in what order, is shaped entirely by what your account is connected to and what you're willing to lose.
