When managing emails on your hosting account with Roundcube webmail, you may encounter greyed out emails in your inbox. This issue usually occurs after a server transfer due to incorrect configuration, but can be easily resolved by adjusting your Roundcube settings.

Understanding how to troubleshoot this issue is essential for maintaining a smooth email experience. If you’re experiencing other email problems, you might also want to check email size limits, as large emails can sometimes cause display issues in webmail clients.

In this short guide learn how to access Roundcubes settings and resolve this issue.

1. First start off by logging into your cPanel account.

2. From your cPanel control panel click Email Accounts in the Email section as shown below.

Use an alternative email client

If the issue persists, you might want to migrate emails with Outlook or another email client whilst the issue is being resolved. This ensures you can continue accessing your emails without interruption.

Still having problems? Migrate emails with Outlook whilst you sort this out. At least you can keep working.

Worth checking email size limits too. Oversized messages sometimes cause display issues in webmail.
