Exporting IMAP emails to an MBOX file in 2026 is fairly straightforward when the mailbox is accessible through IMAP. The usual approach is to connect to the account using its IMAP server details, select the required folders and save the emails in MBOX format.
A practical option is Softaken IMAP Mail Backup, which can connect to an IMAP account and export emails to MBOX. It also lets you filter the mailbox data, choose the required destination and retain the existing folder and subfolder structure. The software requires an internet connection because the emails are fetched from the IMAP server during the backup.
If you have a large mailbox, I would first run a small batch and verify the resulting MBOX file in your target email client before exporting the complete account.
