There are a few reasons you might want to remove an email account from Outlook: a job change, a mailbox you no longer need, or just an account that ended up there and never got cleared out.
Removing an email account from Outlook takes a few steps, and they differ depending on whether you're using Classic Outlook, New Outlook, Mac, or your phone. This guide covers all of them.
Before you remove the account
If there's anything in that account you want to keep, export it or check the server first. Removing an account from Outlook clears the local cache.
For Microsoft 365 and Exchange accounts, your emails live on the server, so disconnecting Outlook won't delete anything. You can still access the mailbox through a browser. For POP3 accounts, the situation is different: emails downloaded to your local machine may not exist anywhere else, so it's worth checking before you proceed.

How to remove an email account from Classic Outlook on Windows
Open Outlook and click File in the top-left corner.
Select Account Settings, then click Account Settings again in the dropdown.
In the Email tab, select the account you want to remove.
Click Remove.
Confirm when prompted.
Outlook will ask you to confirm before removing the account. Restart Outlook once done; the account won't fully disappear from the interface until you do.
How to remove an email account from New Outlook on Windows
New Outlook (the updated version rolling out across Windows 11) uses a different navigation path.
Go to the View tab and select View settings, or use File > Account info.
Select Accounts > Your accounts.
Find the account you want to remove and select Manage.
Under Account details, select Remove.
Choose whether to remove from this device only or from all devices.
The option to remove from all devices is useful if you've connected the same account across a work laptop, home machine, and phone. One step handles all of them.
How to remove an email account from Outlook on Mac
Open Outlook and go to Tools in the menu bar.
Click Accounts.
Select the account you want to remove from the left sidebar.
Click the minus (–) button at the bottom-left of the Accounts window.
Confirm by clicking Delete.
The minus button has no label, which is the part most people miss the first time. If the Accounts window looks different to what you expect, check that you're in the Tools menu rather than Preferences.
How to remove an email account from Outlook on iPhone or Android
On iOS:
Open Outlook and tap the profile icon in the top-left corner.
Tap the gear icon to open Settings.
Scroll to the account you want to remove and tap it.
Tap Delete Account.
On Android, the steps are essentially the same. Tap the profile icon, open Settings, select the account, and choose Delete Account. The exact wording varies slightly by Android version.
Deleting an account from the Outlook app doesn't sign you out of any other Microsoft services on your phone. It only removes that inbox from the Outlook app itself.
Removing vs. disconnecting vs. deleting
Removing an account from Outlook disconnects it from the app. It does not delete the mailbox or its contents. The emails remain on the server. You can still log in through a browser or reconnect the account later.
If you want to close the email account entirely, that's a separate process handled by your email provider: Microsoft, Google, or whoever hosts the mailbox. Outlook removal just severs the local connection.
The distinction matters if you're leaving a job. Removing the account from Outlook is something you control locally. Whether you still have access to the mailbox at all depends on what IT has provisioned; that's separate.
What happens to contacts and calendar entries
Email isn't the only thing tied to an account in Outlook. Contacts and calendar entries synced from that account will also disappear from Outlook once you remove it.
For Exchange and Microsoft 365 accounts, those contacts and calendar entries still exist on the server. Reconnecting the account restores them. But if you need that data in your personal Outlook contacts or calendar going forward, export it before removing the account.
To export contacts: go to File > Open & Export > Import/Export, select Export to a file, and choose Comma Separated Values. For calendar data, use the same export path and select Outlook Data File (.pst).
It's a small step that's easy to skip, and harder to undo after the fact. If you're removing an account after leaving a role, it's also worth noting that some organizations revoke server access quickly once an account is deactivated. Once that happens, even reconnecting Outlook won't recover the data.
When the problem is bigger than the account
Sometimes an account gets removed not because it's the wrong inbox, but because the inbox itself has become unmanageable. According to Fyxer's Admin Burden Index 2026, a survey of 5,000 UK and US office workers, email is the single biggest time-wasting admin task, with workers losing 5.6 hours per week to admin that AI could handle.
2024 research published in Frontiers in Psychology found the same pattern: high email load disrupts workflow and overtaxes the capacity to focus on prioritized tasks, particularly when the inbox offers no automatic structure.
Outlook's Focused Inbox offers basic filtering, but it doesn't learn from how you actually work or draft responses for you. If volume is the issue rather than the account setup, tools like Fyxer sit inside Outlook and organize emails by priority before you open them, so the inbox you're left with is the one that actually needs your attention.
Clearing out an account you no longer need is a quick win. If the inbox that's left is still more than you can realistically keep on top of, the volume's the problem, not the account itself.
Removing email account from Outlook FAQs
Will removing an account from Outlook delete my emails?
No. Removing the account disconnects it from Outlook but doesn't affect the mailbox or its contents. Your emails remain on the server and are accessible through a browser or another email client.
Can I re-add an account after removing it?
Yes. Go back to Account Settings (Classic Outlook) or Accounts (New Outlook / Mac) and add it again. You'll need your email address and password.
Why does Outlook ask me to restart after removing an account?
Outlook rebuilds its profile after a change like this. A restart ensures the update takes full effect and avoids display issues.
What if Outlook won't let me remove the account?
If the account you're trying to remove is the only one set up in Classic Outlook, you'll get a warning that you need to create a new data file location before removing it. Outlook requires at least one active account in a profile. The fix is either to add a replacement account first, or to delete the Outlook profile entirely and create a new one. Microsoft's support documentation walks through both options.
