Import Emails From Outlook to Gmail: 4 Methods That Work

The average professional spends about 28 percent of the workday on email and fields roughly 120 messages a day, per a McKinsey analysis published by Harvard Business Review — so when you switch from Outlook to Gmail, years of that mail is what you’re trying to carry over without losing a thread. As of 2026 there are four real ways to do it: Gmail’s built-in POP import, the .pst export route loaded back through a desktop client, the add-account / Gmailify shortcut, and the Workspace data migration service for whole organizations. I’ve migrated several mailboxes both ways, and the right method depends entirely on whether you care about preserving folders. Here’s each one, with the gotcha that decides it.

Which Method Fits Your Situation

There are four ways to import Outlook mail into Gmail in 2026: Gmail’s built-in POP import (fastest, no software, but drops folders), a .pst export dragged in over IMAP (preserves folders, needs a desktop client), the add-account / Gmailify route (read Outlook inside Gmail without fully migrating), and the Workspace data migration service (admins moving a whole organization).

Before you click anything, answer one question: do you need your Outlook folder structure to survive the move? That single decision routes you. Gmail’s one-click import is genuinely effortless, but it imports messages only — not folders or labels¹ — so everything lands in one inbox you re-file by hand. If your Outlook account has thirty carefully sorted folders, that’s a deal-breaker, and you want the .pst-plus-IMAP route instead.

The second question is scale. One personal mailbox is a self-serve job; an entire company on Microsoft 365 is an admin job with its own tool. Mixing those up — trying to migrate fifty employees with per-user POP import — is the most common way people turn a one-day migration into a two-week one. If you’re weighing the move at all, our look at Outlook alternatives in 2026 covers why Gmail is the usual landing spot, and running Gmail and Outlook together is the option for people who’d rather not pick a side at all.

Method 1: Gmail’s Built-In POP Import

In Gmail, open Settings, then Accounts and Import, and use “Import mail and contacts” or “Add a mail account” to pull your Outlook messages over POP. It needs no software and runs in the background, but it imports messages only — not folders or labels.

This is the path Google designed for exactly this job. Open Gmail, click the gear, go to See all settings, then the Accounts and Import tab, and choose Import mail and contacts (or Add a mail account). Enter your Outlook address and credentials, and Gmail connects over POP to fetch your existing mail.¹ It will also keep forwarding new messages sent to your Outlook address into Gmail for 30 days, which is a useful grace period while you tell contacts your new address.

The two things to know up front: Gmail imports messages but not your folder or label structure, so a tidy Outlook account arrives as a single undifferentiated pile in your Gmail inbox.¹ And Google’s help page notes you can’t add every Outlook account this way on every interface — if the Add a mail account flow refuses your address, that’s the limitation, not a bug, and Method 2 is your fallback. When I tested the POP import on a mid-sized personal mailbox, the fetch ran in the background over several hours rather than finishing instantly.

Best for: a single personal account where you don’t care about preserving folders and want zero software installed.

Method 2: The .pst Export and IMAP Drag

Export Outlook to a .pst file as a backup, then connect both the .pst and your Gmail account in a desktop client over IMAP and drag the folders across. Unlike POP import, this preserves your Outlook folder structure as Gmail labels.

This is the method to use when folders matter. First, make the backup: in classic Outlook, go to File, then Open & Export, then Import/Export, choose Export to a file, then Outlook Data File (.pst), pick the account, keep Include subfolders checked, and choose a save location (you can set a password).² Note that in new Outlook, calendar and contacts in .pst aren’t available — you need classic Outlook for those.² That .pst is your safety net even if you end up importing another way; full details on exporting live in our Outlook .pst and Takeout export guide.

Then enable IMAP in Gmail (Settings → Forwarding and POP/IMAP → Enable IMAP), and connect both accounts in a desktop client — classic Outlook, Thunderbird, or Mailbird all work, and having both mailboxes side by side in one window is what makes managing the move painless. Drag the messages from the Outlook folders into the matching Gmail IMAP folders, and the client uploads them to Gmail, recreating each Outlook folder as a Gmail label. It’s slower to set up than the one-click import, but it’s the only consumer method that keeps your structure intact.

Best for: anyone with a carefully organized Outlook account who needs the folder hierarchy to survive.

Method 3: Add-Account or Gmailify

If you mainly want to keep reading Outlook mail inside Gmail rather than fully migrate, link the Outlook account with Gmailify or as a forwarding/POP account. New mail lands in Gmail with spam filtering and search, while your old archive stays put.

Not every move is a clean break. If you’re keeping the Outlook address alive but want one inbox to live in, the add-account route under Accounts and Import lets Gmail pull and send as your Outlook address, and Gmailify layers Gmail’s spam filtering, search, and categories on top of the linked account.¹ Gmail supports up to five linked addresses, so you can consolidate several accounts this way.¹

The trade-off is that this is consolidation, not migration: your historical Outlook mail stays in Outlook unless you also run Method 1 or 2 to bring the archive over. It’s the right call when the account is still active and you simply don’t want to check two apps. If you’re juggling several addresses long-term, our guides on switching between Gmail accounts and managing multiple email accounts cover the day-to-day workflow once everything funnels into Gmail.

Method 4: Workspace Data Migration for Org Accounts

If you’re an admin moving a company from Microsoft 365 or Exchange, use the Google Workspace data migration service in the Admin console — not per-user POP import. It migrates email for many users at once, with progress reports, and can include calendar and contacts depending on the source.

For an organization, per-user import is the wrong tool entirely. A Workspace administrator uses the data migration service (the data import tool) in the Admin console, which connects to Exchange Online or Microsoft 365 and migrates mailboxes for many users in a single managed job.³ Depending on the source, it can carry over calendar and contacts alongside email, and it generates migration reports so you can confirm each user completed rather than discovering gaps weeks later.³

This is also the path that avoids the consumer add-account limitation altogether — because it authenticates at the org level, it doesn’t run into the per-mailbox POP blocks that can stop Method 1. The setup is heavier (you provision the connection and map users), but for anything past a handful of accounts it’s the only sane option.

Best for: admins migrating a whole company off Microsoft 365 or Exchange in one controlled pass.

The Gotchas That Trip People Up

The recurring snags are folder loss on POP import, Outlook accounts that can’t be added on some interfaces, slow background fetches for large mailboxes, and assuming per-user import scales to a whole company. Each has a documented fix.

A few traps catch nearly everyone. Folder loss: if your folders vanished, you used POP import, which only carries messages — re-run via the IMAP drag if structure matters.¹ The blocked add-account: Google’s help is upfront that some Outlook accounts can’t be added on every interface; don’t fight it, switch to the desktop-client route.¹ The slow fetch: large mailboxes import in the background over hours or days, not instantly, and the 30-day forwarding window is your buffer while it finishes.¹

The biggest one is scale. Per-user POP import is a personal tool; pointing it at a fifty-person migration guarantees pain. The moment you’re moving more than a couple of accounts, that’s the Workspace data migration service’s job.³ Get the method right for your scale and the migration is boring — which, for moving years of mail, is exactly what you want.

Verdict

Use Gmail’s built-in POP import for a quick single-account move where folders don’t matter, the .pst export plus IMAP drag when you need folder structure preserved, the add-account route to read Outlook inside Gmail without migrating, and the Workspace data migration service for whole organizations.

The honest summary: there is no single best way to import Outlook mail into Gmail — there’s a best way for your situation, and it hinges on two questions. Do you need folders preserved, and are you moving one mailbox or a company? Answer those and the choice is obvious: one-click import for speed, .pst-plus-IMAP for structure, Gmailify for coexistence, Workspace migration for scale. Make the .pst backup first regardless, and a migration that sounds daunting becomes a background task you barely notice.

Best for: anyone moving from Outlook to Gmail who matches their method to whether folders and scale matter.

Skip if: you only need to read both accounts side by side without moving anything — in that case running Gmail and Outlook together is simpler than any import.

Frequently Asked Questions

What is the easiest way to import emails from Outlook to Gmail?

For a single personal account, Gmail’s built-in import is the easiest: open Settings, then Accounts and Import, then “Import mail and contacts” (or “Add a mail account”), and let Gmail pull your Outlook messages over POP. It needs no software and runs in the background. The catch is that it imports messages only, not your Outlook folder structure, and Gmail’s own help notes you can’t add an Outlook account this way on every interface — if that route is blocked for your address, use the desktop-client IMAP drag method instead.

Does importing from Outlook to Gmail keep my folders and labels?

Gmail’s built-in POP import does not — Google’s help is explicit that it imports messages but not folders or labels, so everything arrives in your Gmail inbox and you re-file it afterwards. If keeping folder structure matters, use the desktop-client route: connect both accounts over IMAP in Outlook, Thunderbird, or Mailbird and drag the folders across. IMAP preserves each Outlook folder as a matching Gmail label, which is the main reason to choose it over the one-click import.

How long does importing Outlook email into Gmail take?

Gmail’s POP import is not instant. After you start it, Gmail fetches your existing Outlook messages in the background and can take anywhere from a few hours to a couple of days for a large mailbox, and it also forwards new mail to Gmail for 30 days while the migration settles. The drag-and-drop IMAP method is faster to start but bound by your upload speed and Gmail’s sync throttling, so very large mailboxes still move in waves rather than all at once.

Should I export Outlook to a .pst file before importing to Gmail?

Yes — make the .pst first. Exporting to an Outlook Data File (File, then Open & Export, then Import/Export, then Export to a file) gives you a complete local backup before you touch anything, so a failed or partial import costs you nothing. It’s also the source you load into a desktop client for the IMAP drag method. Treat the .pst as your safety net even if you ultimately migrate with POP import.

Can I migrate a whole company from Outlook to Gmail at once?

Yes, but not with per-user POP import — that’s a personal tool. For an organization on Microsoft 365 or Exchange, an admin uses the Google Workspace data migration service (the data import tool) in the Admin console, which migrates email for many users in one managed job and, depending on the source, can include calendar and contacts. It produces progress reports and avoids asking every employee to import their own mailbox by hand.

Why can’t I add my Outlook account to Gmail on my computer?

Google’s own help page notes that on some interfaces you can’t add an Outlook.com account to Gmail directly, usually because of how the account’s POP or authentication is configured on Microsoft’s side. When the built-in route is blocked, the reliable fallbacks are the desktop-client IMAP drag (connect both accounts in Outlook, Thunderbird, or Mailbird and move the mail) or, for an org account, the Workspace data migration service. Both bypass the consumer add-account limitation.
