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

Deleting an Outlook email account sounds straightforward — but the actual steps, and the consequences, depend heavily on which type of account you're dealing with and where you're trying to remove it. Getting this wrong can mean losing data you didn't intend to lose, or simply finding that the account keeps coming back.

Here's a clear breakdown of how it works.

The Critical Distinction: Removing vs. Deleting 🗑️

Before touching any settings, it helps to understand that "deleting an Outlook account" can mean two very different things:

  • Removing an account from the Outlook app — This disconnects the account from the app on a specific device. Your emails, contacts, and data still exist on Microsoft's servers (or wherever the account is hosted). You can re-add it anytime.
  • Permanently closing a Microsoft account — This deletes the actual account, including all associated data: emails, OneDrive files, Xbox profiles, and anything else tied to that Microsoft account. This is irreversible after a grace period.

Most people asking this question want the first option. Permanently closing a Microsoft account is a much bigger decision with far-reaching consequences.

How to Remove an Outlook Account from the Outlook App (Windows)

If you're using the Outlook desktop app on Windows, here's the general process:

  1. Open Outlook and go to File in the top-left corner.
  2. Select Account Settings, then click Account Settings again in the dropdown.
  3. Under the Email tab, select the account you want to remove.
  4. Click Remove.
  5. Confirm the removal when prompted.

This removes the account from that installation of Outlook only. No emails are deleted from the server — they're simply no longer syncing to that device.

Important variable: If the account you're removing is the only account configured in Outlook, the app may not allow removal without adding a replacement account first, or it may reset to a first-launch state.

How to Remove an Outlook Account on Mac

On Outlook for Mac, the path is slightly different:

  1. Open Outlook and go to Tools in the menu bar.
  2. Select Accounts.
  3. Choose the account from the left-hand sidebar.
  4. Click the minus (–) button at the bottom of the sidebar.
  5. Confirm the removal.

Again, this only affects the local app — not the underlying account data.

How to Remove an Outlook Account from a Mobile Device 📱

On iOS and Android, Outlook accounts can be managed either through the Outlook mobile app or through the phone's system settings — and these behave differently.

In the Outlook mobile app:

  • Go to Settings (your profile icon) → tap the account → scroll to find Delete Account.

In iPhone system settings:

  • Go to Settings → Mail → Accounts, select the account, and tap Delete Account.

In Android system settings:

  • Go to Settings → Accounts, select the account, and choose Remove Account.

Removing via the system settings affects not just the Outlook app but any other app on the phone that was syncing that account (calendar apps, contacts, etc.). Removing within the Outlook app itself typically only affects that specific app.

How to Permanently Close a Microsoft (Outlook.com) Account

If your goal is to fully close an Outlook.com or Microsoft account — not just disconnect it from a device — the process runs through Microsoft's website, not the app.

General path:

  1. Sign in at account.microsoft.com.
  2. Go to Your Info or Security, then find Account closure or Close your Microsoft account (found under advanced account settings).
  3. Microsoft walks you through a checklist of what will be permanently lost.
  4. You confirm the closure and enter a grace period (typically 60 days) during which the account can be recovered.
  5. After that period, the deletion is permanent.

What gets deleted permanently: All Outlook.com emails, OneDrive files, Microsoft 365 subscriptions linked to that account, Xbox game history, Skype credits, and any app or service using that Microsoft login.

This is a significant action with no undo once the grace period ends.

The Variables That Change Your Situation

The right steps — and the right decision — depend on factors specific to your setup:

VariableWhy It Matters
Account typePersonal Microsoft account vs. work/school account (managed by an organization)
PlatformDesktop app, web browser, mobile — each has different settings paths
Account ownershipYou may not be able to close a work or school account yourself
Linked servicesOther Microsoft services tied to the account will also be affected
Data you want to keepEmails, contacts, and files may need to be exported before deletion
Outlook app versionClassic Outlook vs. the newer "New Outlook" interface have different menu layouts

Work or school accounts managed through Microsoft 365 or an employer's IT system are a separate category entirely. In most cases, individuals cannot close those accounts — only an administrator can. Removing it from a device is possible, but closing it outright is typically not a self-service action.

Before You Delete: Things Worth Checking

Regardless of which path applies to you, a few things are worth confirming first:

  • Export or back up any emails you may need later (Outlook supports .pst export on Windows).
  • Check what else is linked — two-factor authentication apps, subscription services, or third-party logins using "Sign in with Microsoft."
  • Verify which account you're targeting if you have multiple Outlook or Microsoft accounts — it's easier than expected to act on the wrong one.

The difference between removing an account from an app and permanently closing it is significant. What your situation actually calls for depends on why you're leaving, what device you're on, and whether the account belongs to you alone or to an organization.
