A personal account, not a work or school account

Outlook.com Backup Tool is for free Outlook.com, Hotmail, Live and MSN addresses. A work or school address that happens to end in a company domain is a Microsoft 365 mailbox and is covered by the Office 365 backup tool. An older @hotmail.com address has its own Hotmail backup tool page.

Core features

Outlook.com Backup, Step by Step

Five screens, in the order an Outlook.com backup runs from sign-in to the written file.

Adding an Outlook.com account in Outlook.com Backup Tool

Connect

Sign In on the Microsoft Page

Pick Outlook.com from the list and the server details fill themselves in. A Microsoft sign-in window opens, you enter your address and password there, approve the two-step prompt if the account has one and the mailbox loads. Outlook.com Backup Tool never sees the password.

  • Server address filled in automatically
  • Two-step verification, also called MFA, works as normal
  • No app password to generate, Microsoft removed those for personal mail
  • Back up more than one account in a single pass, each signed in separately
Mailbox folder tree with checkboxes

Folder selection

Choose the Outlook.com Folders

The mailbox opens as a folder tree with a checkbox on every branch and a message count beside it. Twenty years of Hotmail can be saved whole, or a single old folder pulled out on its own. Junk and Deleted are left out with one click each.

  • Every folder and subfolder has its own tick box
  • Item counts appear beside each folder up front
  • The nested folder layout is preserved on disk
  • Blank folders can be tucked away in compact view
Message preview with hex and raw views

Message preview

Read Any Message First

Each message opens in a preview pane with four analysis views beside it. Anyone saving an old account before it is closed uses the preview to confirm the right mail is being kept.

  • Content shows body, sender, recipient and subject
  • Message header exposes routing and delivery hops
  • Properties lists size, priority and attachments
  • Hex and raw message give the full source
Filter options for a selective backup

Selective backup

Narrow an Outlook.com Backup

Filters are applied before the run starts, so only the mail you asked for is written. A decade of newsletters can be left behind while the messages that matter are kept.

  • A start date and an end date bracket the run
  • Sender, recipient, subject or message content
  • Restrict the run to mail that has an attachment
  • A size threshold to skip the heaviest mail
  • Skip junk or duplicate messages
Backup format and destination options

Output options

Backup File or Second Mailbox

The target is the final step. Point the output at a folder, a plugged-in drive or a shared network path, or hand the mail to another mailbox instead of a file. Files in a document format are named to a pattern, so a large export stays easy to search.

  • Mail formats: PST for Outlook, MBOX for Thunderbird or Apple Mail, EML, MSG
  • Document formats: PDF, HTML, CSV, TXT
  • Straight into Gmail, a Microsoft 365 account or any IMAP host with the email migration tool
  • Attachments, email addresses and phone numbers pulled out on their own

Before you connect

Signing In to Outlook.com

Microsoft changed the rules for personal accounts in September 2024, and most older guides still describe the way it used to work. Three things to know before you add an account.

Changed

Your password alone no longer works

In September 2024 Microsoft switched off password based sign-in for third party mail software on personal accounts. Any program that asks you to type an Outlook.com password into its own form is refused. Outlook.com Backup Tool opens Microsoft's sign-in window instead and receives a token, not your password. Microsoft refers to the method as modern authentication.

Not needed

App passwords were removed too

Older Hotmail guides tell you to create an app password. Microsoft ended those for personal accounts in the same change. If a guide from before 2025 mentions one, it is out of date. Two-step verification, an authenticator app or a security key all work through the normal Microsoft prompt.

Same login

One account covers all four names

An address ending in outlook.com, hotmail.com, live.com or msn.com is one Microsoft account. Sign in once with whichever address you use and the whole mailbox loads. There is nothing to migrate between the names, since they already share a mailbox.

If the sign-in window closes with an error, the account may have sign-in blocked, or it may be a work address on a Microsoft 365 tenant, not a personal account. The Office 365 backup tool is the page for work and school mailboxes.

Why a copy

Why Back Up the Account

A free mailbox is convenient until the day it is not. These are the moments a local copy earns its place.

Inactivity

An account left unused is deleted

Microsoft deletes a personal account after two years of no sign-in, and everything in it goes with it. An old Hotmail address you rarely open is exactly the one at risk. A local copy is the only thing that survives that clock.

Storage

The mailbox has a ceiling

A free Outlook.com mailbox holds 15 GB, shared with the rest of the account. When it fills, new mail bounces. Moving old years to a file on your drive brings the account back under the limit without deleting anything for good.

Lockout

One copy nobody else controls

A forgotten password, a hijacked account or a support queue that never answers can put a mailbox out of reach. Mail written to your own drive stays readable whatever happens to the online account.

Microsoft keeps the service running. Keeping a copy of the data is your side of the deal. Reading a saved file later, with nothing written, is the free email viewer software.

Before you buy

The Free Way vs Paid, for Outlook.com

If classic Outlook is already installed, you can add the account and export it to a PST at no cost. That covers one account and one format. The table shows where it stops.

Task Classic Outlook export Outlook.com Backup Tool
Cost Free with Outlook $99 one time
One account, once, to PST Built for exactly that Also does it, but you are paying for the rest
Which Outlook Classic desktop Outlook only, the new app cannot Outlook not needed at all
Output format PST only Eight output types, PDF and MBOX among them
Date, sender or subject filter The wizard has no filter step Set the date, sender or size, then run
Several accounts Add and export them one after another Several accounts back up in a single pass
Waiting on a sync first Yes, the account must fully sync into Outlook first No wait, it pulls straight from the server
Headers and raw source Hidden inside a properties dialog Every message viewable before you commit

Rows tinted green are the ones where the free route wins.

One account, PST only and classic Outlook already installed: add the account in Outlook and skip the purchase. For a saved file in another format, several accounts at once or a filter on what gets kept, that is where the paid tool earns its place. Turning a finished PST into another format afterwards is the email converter software.

Outlook.com backup walkthrough

Common questions

Outlook.com Backup FAQs

Signing in, what is copied and where Outlook.com Backup Tool stops.

Is Hotmail the same as Outlook.com for a backup?

Yes. Hotmail, Live and MSN addresses were folded into Outlook.com years ago and share one mailbox. Sign in with whichever address you own and Outlook.com Backup Tool reads the whole account. There is nothing separate to back up for the old name.

Why does Outlook.com Backup Tool open a Microsoft window?

Because Microsoft stopped accepting passwords typed into third party mail software on personal accounts in September 2024. Outlook.com Backup Tool hands you to Microsoft's own page, you sign in there and it receives a token that lets it read the mailbox. Your password never passes through the program.

Do I need an app password for Outlook.com?

No. Microsoft removed app passwords for personal accounts in the same September 2024 change. Any older Hotmail guide that tells you to create one is out of date. The Microsoft sign-in window handles two-step verification for you.

Does two-step verification stop the backup?

Yes. The sign-in happens on Microsoft's page, so the authenticator prompt, text code or security key appears exactly as it would in a browser. Nothing has to be turned off first.

Can I back up several Outlook.com accounts at once?

Yes. Add each account with its own sign-in, then queue them to run together. Each writes to its own file, so an old Hotmail address and a current Outlook.com address come out as two clean backups in one session.

Will it save Outlook.com contacts and calendar?

Yes, if the account stores them. Contacts come out as vCard and calendar items as ICS next to the mail. OneDrive files, Skype history and Microsoft To Do are separate services and stay where they are.

What is the difference from the Office 365 backup tool?

It handles free personal accounts, Outlook.com, Hotmail, Live and MSN. A work or school address on a company domain is a Microsoft 365 mailbox with its own retention rules, covered by the Office 365 backup tool. The download is the same, only the sign-in target differs.

PST or PDF for an Outlook.com backup?

PST if the mail may go back into Outlook or another account later. PDF if the copy is for reading or filing and needs to open on any machine without Outlook. The run can be repeated with a different format, so many people write both.

Does it free up space in the Outlook.com mailbox?

Not by itself. The account is only read from, so nothing on Outlook.com is altered. Once you have opened the local copy and checked it, delete the old folders in Outlook.com yourself to bring the account back under its 15 GB limit.

Is there an Outlook.com mailbox size limit?

No. The licensed build places no limit on the amount of mail saved. A large account takes longer because the server limits read speed, but nothing stops before the end. If the line drops mid-run, the backup continues from where it stopped rather than starting over.

Does Outlook.com mail pass through Corbett's servers?

No. Outlook.com Backup Tool runs on your machine and connects from there to Microsoft. The finished file lands wherever on disk you send it. Corbett stores nothing and relays nothing.

Does Outlook.com Backup Tool run on Mac or Linux?

No. Outlook.com Backup Tool is a Windows application only, from Windows 7 through Windows 11 and Windows Server 2008 through 2025. There is no macOS or Linux build.

What does the free Outlook.com backup demo include?

It signs in to any Outlook.com account, loads every folder and gives you the full preview and all the filters. The backup itself stops at 10 emails from each folder, which is enough to open the output and confirm it looks right.

Saved an old Hotmail account

I had a Hotmail address from twenty years back that I barely use. Wanted a copy before it got deleted for being idle. Signed in through the Microsoft window, picked PST and it saved the lot without a hitch.

Paul Whitman

No app password needed

Every guide I read said generate an app password, and none of them worked any more. This one just opened the real Microsoft login, took my code and started reading the mailbox. Wish I had found it first.

Diane Kellerman

Two accounts saved in one go

Needed my Live.com and a newer Outlook.com address both saved before switching to a work setup. Added both, queued them and got two separate PST files. Simple and did exactly what it said.
