Is there any restriction or risk of data loss in the manual method?

Many! RoundCube emails get saved into EML format, and as I said before, you’ll have several EML files if you’re a professional or deal with serial emails in a day, making it a repeated task.

Also, there will be no filter option; you’ve to check every email one by one before exporting it into EML format.

You may export a single email multiple times to export, which will cause duplicity in the Outlook emails.

Apart from these restrictions there are a few possible error which you might face during the importation process.

Possible errors during migration and how to fix them:

  • Data loss: This can occur during the migration process, and it can result in the loss of emails, contacts, and other important data. To prevent this, it is recommended to backup your Roundcube data before starting the migration process.
