Advanced Email Migration to Office 365 from a POP3 Service Provider – Part 4

 

POP3 Email Forwarding to Office 365

Now that we have the user active in Office 365 with both the primary and transition (vanity) domain setup, we can now setup the POP3 Provider to forward all incoming email for userid@contoso.com to userid@mail.contoso.com.

This step is done many different ways, because there are many different POP3 providers. Below is instructions for my POP3 provider (Shaw Communications)

  1. Login to Shaw Webmail with the user account you want to migrate

     

  2. Click Settings

     

  3. Click Mail Settings

     

  4. Enable Mail Forwarding

     

  5. Enable ‘Do not leave copy on server’

     

  6. Enter userid@mail.contoso.com, click Add

     

  7. Click Save

     


 

We are now at the point where we can test.

  1. Send an email to userid@mail.contoso.com (preferably from an external email account – Hotmail works great)
    1. Verify delivery in Office 365 – Outlook Web Access

       

  2. Send an email to userid@contoso.com (preferably from an external email account – Hotmail works great)
    1. Verify delivery in Office 365 – Outlook Web Access

       

  3. Have another POP3 user, from the current provider, send an email to the migrated user (userid@contoso.com)
    1. Verify delivery in Office 365 – Outlook Web Access

       

  4. Reply from Office 365 to the user that just sent the test message from the current POP3 provider

     

  5. Send an email from Office 365 to another user on the current POP3 provider
