Migrating a Google Workspace (Gmail for Business) account to Outlook or Office 365 can be a bit complex for organizations. Below, I’ve broken down the available methods — both manual and professional — so you can choose what works best.
While the manual approach requires technical skills and step-by-step guidance, the professional method makes it easier to migrate single or multiple mailboxes at once.
Manual Method – Google Workspace to Outlook via IMAP Bridge
IMAP migration allows you to access Gmail for Business mailboxes directly inside Outlook. Many organizations prefer Outlook because it’s a more structured and business-friendly platform.
Steps:
Step 1: Enable IMAP in Gmail
Sign in to your Google Workspace Gmail account.
Go to Settings → See all settings → Forwarding and POP/IMAP.
Under IMAP Access, select Enable IMAP → Save changes.
Step 2: Enable App Password
(Google doesn’t allow Outlook to connect using your regular password.)
Go to your Google Account Security settings.
Turn on 2-Step Verification if it’s not enabled.
Create an App Password (choose Mail and Windows Computer).
Step 3: Configure in Outlook
Open Outlook → File → Add Account.
Enter your Gmail address → select IMAP.
Use these server settings:
Incoming: imap.gmail.com | Port: 993 | SSL/TLS
Outgoing: smtp.gmail.com | Port: 465 or 587 | SSL/TLS
Username: your full Gmail address
Password: your App Password
At this point, your Gmail messages will sync with Outlook.
Manual Method 2 – Google Workspace to Office 365 via PST
Once your Gmail account is configured in Outlook, you can export the mailbox as a PST file.
Use the Outlook Export option to generate a PST.
Upload the PST file to Office 365 using the Network Upload method in the Microsoft 365 Admin Center.
This process is technical and best handled with IT assistance.
