Gsuite to O365 Migration

Migration from Google Workspace mailboxes using the Microsoft 365 admin center 

You can use the setup wizard in the Microsoft 365 admin center for an IMAP migration. See IMAP migration in the Microsoft 365 admin center for instructions. Before Microsoft 365 or Office 365 can connect to Gmail or Google Workspace, all account owners must create an app password to access their account.

This is because Google considers Outlook to be a less secure app and will not allow a connection to it with a password alone. 

For instructions, see Prepare your Google Workspace account for connecting to Outlook and Microsoft 365 or Office 365. You'll also need to make sure your Google Workspace users can turn on 2-step verification.
