How to Transfer Office to a New Computer: The Complete Migration Guide

The new computer is on the desk, and Office has to transfer too. The old one still holds Word, your mail and years of templates. To transfer Office to a new computer, start with the license type. Then free the license on the old PC, install on the new one and activate.

All three rules come up every time Microsoft Office setups move between PCs, whoever the machines belong to.

The license is only half the job, though. Templates, Outlook mail, signatures and custom dictionaries live in folders the installer never touches.

They’re what you miss on Monday morning.

Which Office licenses transfer to a new computer

It moves if the license permits it.

Retail one-time purchases such as Office Home 2024 or Office Professional Plus 2021 can move to another computer you own.

Pre-installed Office is married to the hardware it shipped on. For the next PC you end up buying another license.

Telling which license you have

Open Word and go to File, then Account. Look under Product Information.

For key-based installs, the command below shows the last five characters of the key. It also shows the license channel, Retail or Volume.

cscript "C:\Program Files\Microsoft Office\Office16\OSPP.VBS" /dstatus

On the old PC first

Write down how Office is licensed. Find the product key or the Microsoft account it’s linked to. Back up your files and settings. Only then free the license.

Since Office 2013, most one-time purchases are linked to a Microsoft account. Often the “key” is just the email address you activated with.

Keep the old PC working until Office is activated on the other machine. If activation goes wrong, the old files and settings are still there.

Deactivating on the old PC

Current versions have no “Deactivate” button. Uninstalling, plus removing the key, is what frees the license.

Microsoft 365

• In any Office app, go to File, Account and click Sign out.
• If the old PC is already gone, sign in at account.microsoft.com, open Devices and sign the device out of Office.

A retail one-time purchase with a product key

1. Open Command Prompt as administrator.
2. Run the status line below and note the “Last 5 characters of installed product key”.
3. Run the removal line with those five characters.
4. Uninstall Office from Settings, Apps, Installed apps.

cscript "C:\Program Files\Microsoft Office\Office16\OSPP.VBS" /dstatus
cscript "C:\Program Files\Microsoft Office\Office16\OSPP.VBS" /unpkey:XXXXX

We’d keep how to remove an Office product key open for the details. If the normal uninstaller fails, our guide to the Microsoft Office uninstall tool covers the cleanup options.

Skipping this step costs an evening. The other PC refuses to activate and says the key was used too many times. Microsoft still sees the old installation.

Moving Microsoft 365 to a new computer

Office activates automatically when you sign in. Personal and Family install on any number of your devices and stay signed in on five at once.

1. On the new PC, go to account.microsoft.com and sign in with the account that owns the subscription.
2. Open Services & subscriptions and click Install. On microsoft365.com the button reads Install apps.
3. Run the downloaded setup file and wait for the Click-to-Run installer to finish.
4. Open any app and sign in with the same account.

You can keep it running on both machines for a week during the switch. The five-device limit easily covers that. Then sign the old one out.

How to transfer Office to a new computer: one-time purchases

This covers one-time purchases such as Office 2021 or Office 2024. Free the license on the old PC first.

1. Remove Office and its key from the old PC, as described above.
2. On the new PC, install from Services & subscriptions in your Microsoft account. With a key that was never redeemed, go to setup.office.com first.
3. Open Word and activate.
4. Check that File, Account shows “Product Activated”.

If online activation reports too many installs, Microsoft’s official route is telephone activation. It’s fully automated and takes a few minutes.

Microsoft’s support article on activating Office after installing on a different device confirms the rule.

• One-time purchases are licensed for one computer.
• A move is allowed under the license terms.
• You uninstall from the original computer afterwards.

Section 3 of the Office 2016 and 2019 terms covers transfers.

Older one-time versions back to Office 2016 still install and activate. A fresh PC makes a good moment to move to Office 2024.

Need a key? Our Office Home and Business 2024 key comes as a genuine license. We email it instantly after payment.

Very old versions

Office 2010 and earlier weren’t linked to a Microsoft account. You need the original setup files, on disc or as an ISO, and the printed key.

Activation servers for those versions aren’t guaranteed to answer any more. Phone activation may be the only path.

For anything older than 2016, we’d not bother. The time spent outweighs the cost of a current version.

Outlook mail, templates and other data

Copy the files Office keeps outside its program folder.

Mail accounts on Exchange, Microsoft 365 or IMAP sync back from the server on their own. Only local PST archives and POP3 mailboxes need a manual copy.

Moving a PST file

1. In classic Outlook on the old PC, go to File, Account Settings, Account Settings. Open the Data Files tab and note the PST path.
2. Close Outlook and copy the PST to a USB drive or cloud folder.
3. On the other PC, open Outlook and choose File, Open & Export, Import/Export.
4. Pick Import from another program or file, then Outlook Data File. Browse to the copy and finish the wizard.

Don’t bother copying OST files. They’re only caches of a server mailbox and rebuild themselves once you add the account.

Moving a setup this way saves reconfiguring a dozen accounts. People tend to forget one folder of Excel templates.

When Office won’t activate on the new computer

Usually the license is still counted on the old PC. Or the key belongs to a different edition than the one you installed. Or the copy is OEM and can’t move.

Our Office 2024 installation guide shows where to get each installer.

Special cases when you transfer Office to a new computer

A few moves need extra care.

Moving to a Mac

A PC license doesn’t cover a Mac unless the product says “PC/Mac”.

Home and Business 2024 for PC/Mac and Microsoft 365 cover both platforms.

On the Mac, we’d put on a current build and keep it updated. The Microsoft update guide shows how.

Windows 10 to Windows 11

Your apps keep working when you go from Windows 10 to Windows 11. Office 2016 and later install normally on Windows 11.

Business licenses

Business and volume licenses follow the organization’s agreement. They can move between machines, but only with the paperwork the agreement asks for.

Check with whoever bought them before moving anything. Our overview of Microsoft Office versions lists every edition and its license type.

Upgrading and not moving

An old laptop with Office 2013 isn’t worth the fight with old activation servers. We’d buy a current version for the next PC.

What to check afterwards

Ten minutes of checks beat discovering a missing template on a deadline.

1. Open each app once and confirm activation under File, Account.
2. Click Update Options, Update Now on the same screen.
3. Create and save a document from one of your templates.
4. Send a test email and check your signature.
5. Run your macros and add-ins. Re-enable add-ins under File, Options, Add-ins if needed.
6. If anything misbehaves, run Quick Repair from Settings, Apps, Installed apps, Microsoft Office, Modify. Try Online Repair if that fails.

Quick Repair typically takes a couple of minutes and keeps your settings. It’s a common fix for add-ins that refuse to load after a move.

Typical transfer problems and fixes

The laptop bundle

Someone tries to move the Office that came with an old laptop to a desktop. It won’t activate there. That copy belongs to the laptop. The desktop needs its own license.

Too many activations

The old PC was never cleaned, and the other one says the key was used too often. Phone activation from the wizard settles it in a few minutes.

The dead machine

An old PC won’t start at all. With Microsoft 365 the device gets signed out online. With a one-time purchase, phone activation does the job.

The missing mail

After the move, old POP mail is gone from Outlook. It sat in a PST file on the old disk. Once imported, the mail is back.

The wrong edition

A Professional Plus key meets a Home and Business install. Activation fails. With the matching edition installed, the key works.

The swapped motherboard

After a hardware swap Office asks to activate again. Signing in with the same account is all it takes.
