How to Copy (Migrate) Emails Between Google Workspace User Accounts

First, on the top left, type a name for the spreadsheet – in this case, we named it Migration CSV.

Next list all mailboxes involved in the migration, as shown in the image above.

On each row, you need to list a single source mailbox to migrate emails from and a single destination mailbox to migrate mail to:

1. The destination mailbox you will migrate to goes in the first column (where we put in “Google Workspace Email”)
2. The source mailbox you will migrate from goes in the second column.
3. The password of the source mailbox you will migrate from goes in the third cell.
4. If the destination and source have the same email address, the second cell should be left empty, as we’ve done on rows 2 and 4.

    

In the example above, in row 1, we have the Google Workspace email we want to migrate mail into in cell A.
In cell B, we have the source email we want to migrate.
In cell C, we have the password of the email account in cell B.

In row 2, in cell A we have the Google Workspace email we want to migrate mail to.
Cell B is empty because the email we want to migrate from is the same as the Google Workspace email.
In cell C, we have the password of the account we want to migrate.
