    • Use the default job name or select 'New Job' to customize the name.

      

  • Step 2: Connect to the source EarthLink email server

    • To migrate a single user account, choose ‘Single User / Account Migration.’ Next, select the desired protocol, like ‘Connect to IMAP’ or ‘Connect to POP3,’ and click ‘Next’ to move forward.

      

    • Choose the correct IMAP host name from the list or manually enter it (e.g., mail.yourdomain.com). Then, fill your email address, password.
    • Click the ‘Login’ button.

      

    • For migrating multiple Earthlink mailboxes, select ‘Multiple (Bulk) Users/Accounts Migration’ and click ‘Next’.

      

    • Click ‘Download Sample CSV File’.

      

    • Modify the CSV file with the required details such as email address, password, host name and port number in the CSV file and save the changes.

      

    • Once you've made the necessary changes to the CSV file, save and close it.
    • Then, click on the 'Browse CSV File' button, find your updated file, select it, and open it to continue.

      

  • Step 3: Select the mailboxes or folders to migrate

    • Select the mailboxes or specific folders you want to migrate, then click ‘Next’ to proceed with the migration process.

      

  • Step 4: Connect to the target Office 365 server

    • Click the ‘Add New Connection’ button to establish a new connection to the target Office 365. To use the previous connection, select it from the connection list and click the ‘Connect to Existing’ button to proceed.

      

    • Select the required connection options and click the ‘Next’ button.

      

    • Select the authentication method and click the ‘Login’ button to continue.

    • EdbMails allows you to load mailboxes automatically, which is quick and convenient. However, due to Microsoft API limitations, the automatic method can list up to 100 mailboxes at a time. For larger environments or to include specific mailboxes beyond this limit, you can use the CSV file method to load mailboxes manually, giving you full control over the selection process.
    • Click the ‘Next’ button to continue
