Mailboxes of respective mail domains can be migrated across different messaging platforms with Mail Data Migrator. Mailboxes should be added to mail domains before migration. Only after they are added and verified, the syncing process can initiate.
To add a mailbox, click +Add from the top menu and then +Add Mailbox. Select the affiliated mail domain from the listed domains. To add a single mailbox, specify required details to proceed. In case of adding bulk mailboxes, click Choose File and type/select path of CSV file to proceed.



If the Super Admins or Project Admins are aware of the source user Mailbox passwords, they may simply insert them while adding Mailboxes. If the password is correct, they would be directed to another screen for target Mailbox verification. If the password is incorrect, Mail Data Migrator will throw an error.

If for some reason the Super Admins or Project Admins are not aware of the user Mailbox passwords, Mail Data Migrator has a unique way to handle such migrations. There is an elaborate verification mechanism in place, if the passwords are not available. For details refer to the verification process below.
Password Verification Process: If the Mailbox password is not available, Mail Data Migrator will send a verification mail with a verification link, to the source mailbox. Clicking the link redirects to the Mail Data Migrator login screen. The user can then input the email address and a valid password at the login to pass on a valid password to Mail Data Migrator. The procedure works as follows:
