Corbett Outlook.com Backup Tool Keeps a Personal Microsoft Mailbox on Your PC

Two years without a sign-in and Microsoft closes a personal account, mail included. Outlook.com Backup Tool keeps Focused, Other, Archive and every custom folder on a local drive first. Below is what transfers and what Microsoft keeps.

A personal account, not a work or school account

Outlook.com Backup Tool covers free personal Microsoft accounts. Company or school addresses sit on a Microsoft 365 tenant and belong with the Office 365 Backup Tool. An older @hotmail.com address has its own Hotmail Backup Tool page.

Related backup pages: Hotmail backup tool, Office 365 backup tool, Gmail backup tool and Yahoo backup tool. Any other IMAP account is on the email backup software page.

Quick answer

What Is Outlook.com Backup Tool?

Outlook.com Backup Tool is a Windows program that saves a personal Microsoft mailbox, whether the address ends in outlook.com, hotmail.com, live.com or msn.com. Login happens on the Microsoft page, so passkeys and the Authenticator app work unchanged.

What it saves

Outlook.com mail, attachments, people and calendar

Where it saves

A folder, a USB stick, a NAS share or another live inbox

Who uses it

Anyone with a free Microsoft mailbox

Core features

Outlook.com Backup Tool, Step by Step

The run in five screens, from the Microsoft login to a finished backup file.

Outlook.com sign-in screen with Microsoft login window

Connect

Sign In on the Microsoft Page

Choose Outlook.com and the server fields load by themselves. A Microsoft login window then asks for the address, password and any Authenticator prompt. Once approved, the folder list opens.

Microsoft keeps the token, not the tool. Microsoft dropped app passwords for personal mail, so none is needed. Back up multiple accounts in a single pass, every one signed in separately.

Outlook.com folder tree with message totals and checkboxes

Folder selection

Choose the Outlook.com Folders to Keep

Focused Inbox, Other, Archive, Junk Email and Deleted Items sit in one tree with message totals. Keep two decades of mail in one go or save a single old folder.

Every folder and subfolder has its own tick box. Junk and Deleted can stay behind with one click, and blank folders can be tucked away in compact view.

Outlook.com message preview with content, header, properties and hex tabs

Message preview

Preview Outlook.com Messages First

Open any message in a reading pane with four expert views alongside. Before an old account closes, this is how the owner confirms the right letters, receipts and photos are being saved.

Content displays body, from, to and subject. Message header traces every server hop, properties gives size, importance and attached files, and hex and raw message reveal the original source.

Outlook.com filters by date, sender and size

Selective backup

Back Up Outlook.com Mail by Date or Sender

Set filters first and only matching mail is written. Years of shopping newsletters stay behind while bank letters, tickets and family mail come along.

Bracket the backup with a from and to date, search by sender, recipient, subject or body, keep only mail with an attachment, set a size threshold and leave Junk Email and repeat copies out.

Outlook.com output format and destination options

Output options

Send Outlook.com Mail to a File or a Second Mailbox

The target is the final step. Select a folder, a plugged-in drive or a shared network path. Mail can also go to another mailbox instead of a file, and document formats are named to a pattern.

Outlook PST, plus MBOX, EML and MSG for Thunderbird or Apple Mail, and PDF, HTML, CSV or TXT for reading on any device. Move mail into Gmail or another IMAP server with the email migration tool.

Flexible use

Three Ways to Back Up Outlook.com With One Tool

One personal account, several accounts or a move to another inbox: Outlook.com Backup Tool handles all three. Test your job in free demo before you buy.

Back up one Outlook.com account

Log in on the Microsoft page, tick folders and save a PST or PDF copy before the account goes idle.

Back up several accounts at once

Queue an Outlook.com box and a Live box together. Every account gets its own output file.

Move Outlook.com mail to a new inbox

Name a Gmail or IMAP mailbox as the target and the mail lands in matching folders.

Before connecting

Outlook.com Sign-In With Microsoft Modern Login

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 adding an account.

Changed

Typed passwords are refused

Since September 2024 Microsoft rejects passwords entered into outside mail apps on personal accounts. Outlook.com Backup Tool opens the Microsoft login page and receives a sign-in token, never the password itself.

Not needed

App passwords were removed too

Many old tutorials still tell readers to create an app password. That option disappeared for personal accounts in the same update. Use the normal Microsoft login with Authenticator, a text code or a passkey instead.

Same login

One account covers four names

Addresses at outlook.com, hotmail.com, live.com and msn.com all point to one Microsoft account per person. Log in with any alias and the same mailbox opens, so nothing has to be merged.

A login window that closes with an error means the account may be blocked or the address is a company one on a Microsoft 365 tenant. Work and school mail belongs with the Office 365 Backup Tool.

Working process

How to Back Up Outlook.com Emails in Four Simple Steps

3

Use cases

Outlook.com Backup for Idle, Full or Locked Accounts

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

Owners of idle accounts

Microsoft deletes a personal account after two years without activity. A copy outlives that deadline.

People locked out of mail

Lost passwords or a hacked account can cut access for weeks. A local copy opens regardless.

People with a full 15 GB box

OneDrive photos share the quota. Move older years to a file and free room without losing mail.

Before purchase

Classic Outlook Export vs Outlook.com Backup Tool

With classic Outlook installed, adding the account and exporting a PST costs nothing. It handles one account in one format. Here is where that free route ends.

Task Classic Outlook export Outlook.com Backup Tool
Cost Free with Outlook $99 one time
Single account, single PST export Made for that job Can do it, with the extras below
Which Outlook Classic desktop Outlook, the new Outlook app cannot No Outlook required
Output format PST only PST, PDF, MBOX and five more
Filter by year or sender The export wizard has no filter Set dates, senders or size first
Several accounts Export them one at a time Queued one after another
Full mailbox sync needed Outlook downloads every folder before exporting Pulls from the server mailbox directly
Headers and raw source Buried in an Outlook properties window Full view of any message before it is saved

Rows tinted green are where classic Outlook export wins.

For one account in PST with classic Outlook installed, the built-in export is enough and the purchase can wait. For other formats, several accounts or filtered copies, Outlook.com Backup Tool pays for itself. Existing files can still be turned into other formats by the email converter tool.

User testimonials

Outlook.com Backup Tool Reviews From Users

Drawn from 683 reviews of the Corbett wizard behind Outlook.com Backup Tool.

4.6 out of 5

Pulled from 683 reviews on rating sites and customer emails. Below are three, quoted exactly.

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.

Ravi Menon

Best practice

How to Keep Your Outlook.com Backup Safe

Saved mail is only useful if it opens later. These four habits protect your Outlook.com archive.

Back up before the idle deadline

Microsoft deletes a personal account after two years without activity. Save the mail first.

Open a sample file

After saving, open a handful of messages. Confirm folders, photos and attachments came across.

Keep PST and PDF

Repeat the backup with a second format. PST for Outlook and PDF for reading anywhere is a common pair.

Store a copy elsewhere

Keep one copy on a home drive and one on a USB stick or NAS, named by address and date.

Common questions

Outlook.com Backup Tool Questions

Microsoft login, aliases, storage and the limits of the tool.

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

Yes. Hotmail, Live and MSN were merged into Outlook.com long ago and use one mailbox. Log in with any of your addresses and Outlook.com Backup Tool saves the full account. The old names have no separate mail to save.

Why does a Microsoft login window appear?

Microsoft blocked passwords typed into outside mail apps for personal accounts in September 2024. The tool sends you to the Microsoft login page, you sign in there and a token unlocks the mailbox. Your password never touches the software.

Do I need an app password for Outlook.com?

No. App passwords were removed for personal Microsoft accounts in the same 2024 update. Older tutorials that mention them are out of date, and the Microsoft window takes care of two-step checks.

Does two-step verification stop the backup?

No. Your Authenticator prompt, text code or passkey shows up on the Microsoft page just like in a browser, so nothing needs switching off.

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

Yes. Log in once to every Outlook.com, Hotmail or Live account and queue them together. Every account gets its own output file, so an old box and a current box end up as two tidy backups.

Will it save Outlook.com contacts and calendar?

Yes, where the account holds them. People entries export as vCard and Calendar events as ICS beside the mail. OneDrive files and Microsoft To Do lists live in separate services and are not copied.

What is the difference from the Office 365 backup tool?

Outlook.com Backup Tool covers free personal Microsoft accounts. Addresses on a company domain sit on a Microsoft 365 tenant with their own admin rules, handled 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?

Use PST if the mail may return to Outlook or another account later. Use PDF for reading, printing or filing on a PC without Outlook. A second backup in the other format costs nothing extra.

Does an Outlook.com backup free up mailbox space?

Not on its own. The tool only reads from the account, so Outlook.com stays untouched. After opening the local copy, delete old folders online to drop back under the 15 GB limit.

Is there an Outlook.com mailbox size limit?

The full version has no cap on mailbox size. Large accounts take longer because Microsoft throttles downloads. A dropped connection resumes the session instead of restarting it.

Does my Outlook.com mail go through Corbett?

No. Your PC talks to Microsoft directly and saves the files to a disk you choose. Corbett never receives a copy.

Can I use it on a Mac or Linux PC?

No. Outlook.com Backup Tool installs on Windows 7 to 11 and Windows Server 2008 to 2025 only.

Is there a free Outlook.com backup tool demo?

Yes. It logs in, lists every folder and unlocks preview and filters. Output is limited to 10 emails per folder, which is plenty to check the file before paying.

How long before Microsoft deletes an unused Outlook.com account?

Microsoft deletes a personal account after two years without activity, and the mail goes with it. A Hotmail address from school days that nobody checks is the one most at risk. A local copy outlives that deadline.

Can I back up an account I am locked out of?

Not until access returns, because the tool needs the Microsoft login to read the mailbox. Back up while you still have access and keep the files on a separate drive for the day a lockout happens.

Which Outlook.com folders are saved?

Focused Inbox, Other, Archive, Sent, Drafts, Junk Email, Deleted Items and every custom folder. Nested folders keep their original order, and Junk and Deleted can be skipped with one click.

Can I limit the backup to one sender or year?

Yes. Filters cover From and To dates, sender, recipient, subject, words in the mail, attachments and size. Only matching mail is written.

Can I move Outlook.com mail to Gmail or another mailbox?

Yes. Hand mail over with the email migration tool. For a single file transfer, see Transfer Outlook emails to another account.

Does the tool delete mail from Outlook.com?

No. It only reads the mailbox. Delete old folders yourself once the archive is checked.

Can I open a saved file without Outlook?

Yes. Open it read-only in the free email viewer software or the Free PST Viewer Tool.

Does it work on Windows 7?

Yes. Windows 11 and 10 are supported along with all older versions.

How much does Outlook.com Backup Tool cost?

One payment of $99 buys a lifetime licence for up to 5 machines, with a 30 day refund window.
