Corbett

Outlook.com Backup Tool

Corbett Outlook.com Backup Tool keeps a personal Microsoft mailbox, whether the address ends in outlook.com, hotmail.com, live.com or msn.com, to a Windows drive in eight formats from PST to PDF. Login happens on Microsoft's page, so passkeys and the Authenticator app work unchanged.

Outlook.com Backup Tool for Mail, People and Calendar

A personal account, not a work or school account

Outlook.com Backup Tool covers free personal Microsoft accounts. Company or school addresses run 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.

Core features

Outlook.com Backup Tool, Step by Step

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

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

Connect

Sign In on the Microsoft Page

Choose Outlook.com and the server fields load by themselves. Microsoft's login window then asks for the address, password and any Authenticator prompt. Once approved, the folder list opens and the token is kept by Microsoft, not by the tool.

  • Server address filled in automatically
  • Authenticator app, SMS code or passkey all accepted
  • Microsoft dropped app passwords for personal mail, so none is needed
  • Back up multiple accounts in a single pass, every one signed in separately
Mailbox folder tree with 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 Hotmail in one go or save a single old folder. Junk and Deleted can stay behind with one click.

  • Every folder and subfolder has its own tick box
  • Totals listed per folder before the run starts
  • Subfolder nesting carried over unchanged
  • Blank folders can be tucked away in compact view
Message preview with hex and raw views

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 the mail took
  • Properties gives size, importance and attached files
  • Hex and raw message reveal the complete original source
Filter options for a selective backup

Selective backup

Back Up Outlook.com Mail by Date or Sender

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

  • Bracket the run with a from and to date
  • Search by who sent it, who got it, subject or body
  • Restrict the run to mail that has an attachment
  • A size threshold to skip the heaviest mail
  • Leave Junk Email and repeat copies out
Backup 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. Files in a document format are named to a pattern, so a large export stays easy to search.

  • Outlook PST, plus MBOX, EML and MSG for Thunderbird or Apple Mail
  • PDF, HTML, CSV or TXT for reading on any device
  • Move the mail into Gmail, a work Microsoft 365 box or any IMAP server through the email migration tool
  • Pull attachments, email addresses or phone numbers into separate files

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 therefore opens Microsoft's own login page and receives a sign-in token, never the password itself.

Not needed

App passwords were removed too

Many Hotmail tutorials still tell readers to create an app password. That option disappeared for personal accounts in the same 2024 update. Use the normal Microsoft login with Authenticator, a text code or a passkey instead.

Same login

One account covers all 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.

When the login window closes with an error, the account may be blocked or it may be a company address on a Microsoft 365 tenant. Work and school mail belongs with the Office 365 Backup Tool.

Why a copy

Outlook.com Backup for Idle, Full or Locked Accounts

A free mailbox is convenient until the day it is not. These are the moments an Outlook.com backup tool copy earns its place.

Inactivity

An account left unused is deleted

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.

Storage

The mailbox has a ceiling

Free Outlook.com storage is 15 GB, and OneDrive photos count against it too. A full mailbox bounces incoming mail. Moving older years into a local file frees room without deleting a single message first.

Lockout

A copy outside the account

Lost passwords, a hacked account or a support chat that goes nowhere can cut access for weeks. Mail kept on a local disk opens regardless.

Microsoft runs the servers, but the data stays the account holder's job under its service terms. Saved files can be opened later, untouched, in the free email viewer software.

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 Built for exactly that Can do this as well, though the price buys the extra rows
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
Filter by date, sender or subject 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
Full sync required 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 the run

Rows tinted green are the ones where classic Outlook wins.

For one account, PST only, 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.

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 Microsoft's own 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 Hotmail 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 Microsoft's 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 Hotmail box and a current Outlook.com 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?

This tool covers free personal Microsoft accounts. Addresses on a company domain run on a Microsoft 365 tenant with their own admin rules, handled by the Office 365 Backup Tool page. 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 run 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 run 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.

Step by step

Outlook.com and Hotmail Help Guides

Guides for the jobs before and after an Outlook.com backup.

All supported providers appear on the email backup software page. Moving an Outlook.com account to another provider is handled by the email migration tool. To browse a saved file with nothing exported, use the free email viewer software. Apple mailboxes use the iCloud backup tool, business Google mail the Google Workspace backup tool and cPanel mailboxes the Webmail backup tool.

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.
