Comcast to Office 365 migration

• Comcast email is primarily linked to the Xfinity internet, so unsubscribing from Xfinity also means you'll lose access to your email which is one of the reasons for migration.
• Microsoft 365 is a specialized suite that focuses on Office applications, emails, collaboration, and cloud sharing.
• You can integrate your email with Outlook and have access to SharePoint, OneDrive, and Teams all under one roof with Office 365.
• Office 365 is a self-contained email solution and does not require a separate domain or hosting provider.
• It is simple to add a Public folder, configure Shared mailboxes, and aliases, from Microsoft's admin center.
• Your email will be stored on secure Microsoft servers rather than on Comcast.

  • Step 2: Connect to source Comcast server

    • If you want to migrate a single user, enter the Host Name , Port Number (993 for SSL), and account credentials to connect to Comcast as shown.

      

    • For migrating multiple mailboxes, choose the 'Multiple (bulk) Users/Accounts Migration' option. Start by downloading the sample CSV file from EdbMails and complete the necessary fields, including mailbox name, password, host name, and port.

  • Step 4: Connect to target Office 365 server

    • Select the preferred method for secure OAuth-based modern authentication. The default option, ‘Auto Registration’, requires Global Admin permissions for configuration, ensuring a streamlined setup process. Alternatively, the ‘Manual Registration’ option provides greater flexibility, as it can be completed using either a Global Admin account or any user account with the necessary full access privileges.

    • EdbMails offers an automated mailbox creation feature for Office 365, simplifying the setup of target mailboxes and ensuring smooth mailbox and folder mapping from the source IMAP server. This feature is useful for managing a large number of mailboxes during migration.

      

    • Click the ‘Folder and Item Filter’ button to set a filter for your migration. For instance, you can choose to migrate data only within a specific date range by applying a date filter. Additionally, you can exclude both standard and custom folders from the migration.

      

  • Step 6: Start Comcast to Office 365 migration

    • Start and monitor the migration operation after you complete the mailbox mapping. Finally, verify the count of migrated emails, folders and mailbox items with EdbMails text-based migration report. You can also pause and resume the migration.

      

• Step 1: Update the MX records to point to Office 365

  If you have not done this step previously, change the DNS records known as MX records to enable and receive email messages on the target Office 365 server. In addition to this setup, configure the Autodiscover record to allow Outlook to connect to the migrated mailboxes.

• Step 2: Create a new Outlook profile for users in the new domain
