In times of pandemic, I work from home and search which web service is the best? And I think Roundcube is the best webmail service, which works in a cloud-based environment. It is a free and open-source platform.

There is no manual way to import Zimbra messages into Roundcube. But, if you try to switch one platform to another by using IMAP. Still, this method is not working. Because you need to export Zimbra email to TGZ file format, which you save in local computer.

Roundcube only supports importing email as an *.eml or *.mbox file with 50MB of capped space. So, manually migrating Zimbra to Roundcube webmail is impossible and it’s too lengthy process.
