How Can I Back Up IMAP Emails Without Losing Folder Structure or Attachments?

I have been looking for a reliable way to back up my IMAP emails because I want to maintain a separate copy of important business and personal conversations. Most email providers allow users to access messages online, but I am concerned about losing access to older emails if an account is suspended, a server encounters problems, or I decide to switch email providers.

I understand that IMAP synchronizes emails across devices, but does synchronization alone provide a reliable backup? If an email is accidentally deleted from one device or the server, it may also disappear from other connected devices.

I would like to understand the best approach to back up IMAP emails locally while keeping the original folder hierarchy, message headers, timestamps, and attachments intact.

A few things I am particularly interested in:

  • What is the easiest way to create a complete IMAP email backup?
  • Can I save IMAP emails in PST, MBOX, EML, or PDF formats for future access?
  • Is it possible to back up selected folders instead of downloading an entire mailbox?
  • How should users handle large IMAP mailboxes containing thousands of messages and attachments?
  • What precautions should be taken when backing up multiple IMAP accounts?
While researching different approaches, I came across the SysInfo IMAP Backup Tool, which offers multiple export formats, folder selection, date-based filtering, duplicate removal, and batch processing through CSV. These options seem useful for users managing multiple mailboxes or maintaining long-term email archives.

However, I would also like to hear about practical experiences from people who regularly manage IMAP accounts.
 
You can secure your emails while fully preserving folder structures and attachments; you need an easy IMAP backup strategy. The ideal software should seamlessly download entire mailboxes without compromising file attachments or email metadata. You can try TrustVare IMAP Backup Software to back up emails without losing attachments. The software enables you to create attachments. It can back up entire mailboxes as well as particular folders from Gmail, Yahoo, Office 365, and any IMAP-enabled accounts. The application is capable of exporting emails in PST, MBOX, EML, MSG, PDF, HTML, and various other file formats. The software creates the backup while retaining the folder structure and stores the attachments along with their messages.
