How to Migrate Email, Contacts, and Calendars to Microsoft 365

IMPORTANT: Bluehost no longer provides Microsoft 365 (Office 365) services. This article is EXCLUSIVELY intended for existing accounts that still utilize this service.

Mastering email, contacts, and calendar migration to Microsoft 365 ensures smooth business operations, leverages cloud benefits, enhances security, and saves costs. It's a valuable skill for IT professionals, making them more marketable by showcasing their expertise in cloud technology.

You must follow two steps to switch from webmail services like Hord and Roundcube to Microsoft 365 and migrate email, contacts, and calendars. The first step is to export the contacts and calendars from your webmail account, and the second step is to import them into your Microsoft 365 account. The process may vary depending on the email service provider you are using. Still, there are generally simple instructions to follow.



Why Migrate Your Email, Contacts and Calendars to Microsoft 365

People migrate email, contacts, and calendars to Microsoft 365 for several compelling reasons:

  • Cloud-Based Flexibility: Microsoft 365 operates in the cloud, offering the flexibility to access emails, contacts, and calendars from anywhere, at any time, and on any device. This supports remote and hybrid work environments.
  • Enhanced Collaboration: With Microsoft 365, users can collaborate in real-time on documents and projects. The integration between email, calendar, and other Microsoft apps like Teams and SharePoint streamlines communication and project management.
  • Automatic Updates and New Features: Users receive the latest features and updates automatically, ensuring they always have access to the newest tools without needing to manually upgrade software.
  • Scalability: Microsoft 365's subscription model allows businesses to easily scale up or down, adding or removing users as needed, which is ideal for growing businesses or those with fluctuating workforce sizes.
  • Security and Compliance: Microsoft 365 offers robust security features that help protect against cyber threats, along with compliance capabilities that support adherence to data protection regulations.
  • Cost Efficiency: By moving to a cloud-based service, organizations can reduce the costs associated with maintaining on-premises servers and infrastructure. The subscription model also helps in budgeting and controlling IT expenses.
  • Data Management and Reliability: Microsoft 365 provides reliable data backup and recovery solutions, ensuring that critical business information is safeguarded against loss or damage.
  • Professional Email Domain: Using Microsoft 365 allows businesses to use their own domain name for email addresses, enhancing their professional image.

     

How to Export from Roundcube

Mail

Important: There is no way to export folders in Roundcube. Messages will need to be exported individually and then converted for Outlook compatibility.

Exporting Mail

  1. Log in to the Roundcube webmail client.
  2. Select the email you would like to export.
  3. Click the More option, then choose Download .eml to begin the export.
    roundcube-download-eml
  4. Please repeat as needed until all desired email messages have been exported.
Converting Exported Emails into PST

Though Roundcube saves exports as a .eml, this can be converted into .pst format using a free third-party tool, EML to PST Converter. The software maintains the EML message formatting and preserves the attributes associated with the EML message. Once an email is saved in PST format, it can be imported into Microsoft 365.

Contacts

Contacts from Roundcube address books are exported in the vCard format only. Microsoft 365 does not support the import of .vcf files. The .vcf file would need to be imported to Windows and then exported to a .csv file. This can be a tedious process for many contacts, as this must be done individually for each contact.

Calendars

  1. Log in to the Roundcube webmail client and select Calendar.
  2. Select Export, then “Export” on the popup. This will export your calendar to a .ics file.
