Dual Connection: You add both accounts to the same app and drag-and-drop folders. Step-by-Step
Turn on IMAP in your Gmail settings under “Forwarding and POP/IMAP”.

Manual methods can fail if your mailbox is larger than 50GB. When native tools fall short, dedicated third-party software offers automated, error-free transfers.
BitTitan MigrationWiz: The industry leader for enterprise cloud-to-cloud migration. It handles thousands of mailboxes simultaneously with detailed error reporting.
SysTools Gmail to Outlook Converter: Best for local machine migrations. It directly converts Google Mbox/Takeout files into Outlook-ready PST files.
Kernel Gmail Migration: Excellent for filtering data by specific dates or folders before pushing the data to Outlook. Essential Pre-Migration Checklist
To prevent account lockouts or missing data, complete these steps before starting any transfer:
Check Mailbox Size: Ensure your destination Outlook mailbox has enough storage tier to hold your Gmail data.
Enable 2-Step Verification: Google requires 2FA to be active before allowing external migration tools to connect.
Unlink Large Attachments: Google Drive links inside emails do not always transfer cleanly. Download critical files first.
Export Contacts Separately: For the cleanest results, export Google Contacts as a .CSV file and import them directly into Outlook Contacts. If you are planning a migration, let me know:
Are you moving a personal account or an entire business team? Roughly how much data (GB) needs to be transferred?
Do you need to migrate Google Drive files along with your emails?
I can recommend the exact tool or step-by-step guide for your specific scenario.
