How can I upload MBOX to IMAP without using Thunderbird?

Many users find themselves stuck with MBOX files after switching email platforms. Sometimes Thunderbird is not installed, no longer supported, or users simply don’t want to configure another email client just to upload emails. In such cases, the question naturally comes up: how can I upload MBOX to IMAP without using Thunderbird? The answer lies in using a direct approach that works independently of email clients.

With tools like the MailConverterTools MBOX Converter Tool, users can upload MBOX to IMAP by directly selecting their MBOX files from the system. The software reads the mailbox data, displays emails and attachments, and allows users to decide what should be uploaded. This makes the process feel more controlled and less technical. Instead of syncing accounts or troubleshooting connection errors, users simply choose IMAP as the destination and enter their email account details.
