How to Delete an Email Account from Outlook (Any Version)
Removing an email account from Outlook sounds straightforward — and often it is — but the exact steps vary depending on which version of Outlook you're using, which operating system you're on, and whether the account is your primary account or a secondary one. Understanding these differences first saves a lot of frustration.
What "Deleting" an Account in Outlook Actually Means
When you remove an email account from Outlook, you're disconnecting it from the app. You're not deleting the email account itself — your Gmail, Yahoo, or work email still exists on the server. Outlook simply stops syncing and displaying it on your device.
This distinction matters. If you want to permanently close an email address, that's a separate process handled through your email provider's website. Removing it from Outlook just means it no longer appears in the app.
Deleting an Email Account from Outlook on Windows
The process differs slightly depending on whether you're using the classic Outlook desktop app (part of Microsoft 365 or older Office installations) or the new Outlook for Windows (the redesigned version rolling out as a replacement).
Classic Outlook Desktop App (Windows)
- Open Outlook and go to File in the top-left corner
- Select Account Settings, then click Account Settings again from the dropdown
- In the Email tab, select the account you want to remove
- Click Remove
- Confirm when prompted
⚠️ One important limitation: if the account you're trying to remove is your only account, or if it's the default account with other accounts dependent on it, Outlook may prevent removal until you either set a different default or add another account first.
New Outlook for Windows
Microsoft's redesigned Outlook app handles account removal slightly differently:
- Go to Settings (the gear icon, usually top-right)
- Select Accounts, then Email accounts
- Find the account you want to remove and click Manage
- Select Delete account from this device
The new Outlook is still being updated regularly, so the exact menu labels may shift slightly between versions — but the path through Settings → Accounts is consistent.
Deleting an Email Account from Outlook on Mac
- Open Outlook for Mac
- In the top menu bar, click Tools, then select Accounts
- In the left panel of the Accounts window, select the account you want to remove
- Click the minus (–) button at the bottom of the panel
- Confirm the removal
On Mac, Outlook handles both Microsoft and third-party accounts (Gmail, iCloud, etc.) through this same Accounts panel, so the process is consistent regardless of account type.
Deleting an Email Account from Outlook on iPhone or Android 📱
The Outlook mobile app manages accounts slightly differently from the desktop versions.
On iOS or Android:
- Open the Outlook app
- Tap your profile picture or initials in the top-left corner
- Tap the Settings gear icon at the bottom of the left panel
- Scroll down and tap on the email account you want to remove
- Tap Delete Account
- Confirm the deletion
Removing an account from the mobile app doesn't affect Outlook on your desktop or other devices — each installation of Outlook manages its own account connections independently.
Key Variables That Affect the Process
Not every removal goes smoothly, and a few factors determine what you'll encounter:
| Variable | Why It Matters |
|---|---|
| Account type | Microsoft/Exchange accounts may have stricter removal rules than IMAP/POP accounts |
| Primary vs. secondary account | Primary accounts often require you to set a new default before removal |
| Outlook version | Classic vs. new Outlook on Windows have different interfaces |
| Organizational/work accounts | IT-managed accounts may be locked or require admin action to remove |
| Cached data | Large mailboxes leave behind an offline data file (.ost/.pst) that Outlook may not automatically delete |
What Happens to Your Local Data Files?
When you remove an account, Outlook may leave behind a local data file — an .ost file for Exchange/Microsoft accounts or a .pst file for POP accounts. These files can take up significant disk space. They're stored in your user folder and aren't automatically deleted when you remove the account. If storage is a concern, you may want to locate and manually delete these files after removing the account.
Work and School Accounts Behave Differently
If the account you're trying to remove is a Microsoft 365 work or school account, the removal process may be more restricted. Some organizations configure Outlook so that corporate accounts can't be freely removed by end users — this is a security and compliance measure. In these cases, attempting to remove the account may prompt you to contact your IT administrator, or the option may simply be greyed out.
Additionally, if your work account is connected to Windows device management (enrolled in Intune or a similar MDM platform), removing it from Outlook alone may not be sufficient — the account may be linked at the operating system level.
The Part That Depends on Your Setup
The actual steps are consistent enough that most users can follow them without issue. Where things get complicated is at the edges: whether you're on classic or new Outlook, whether your account is managed by an organization, what version of the app your device has installed, and what you plan to do with any leftover local data files.
Someone on a personal Windows laptop removing a Gmail account will have a completely different experience than someone trying to remove a corporate Exchange account from a company-managed device. The right path forward comes down to which of those situations actually describes your setup.
