Downloading the emails from IMAP server is an important task for anyone who is looking to secure the data. The process is explained properly in the guide. Check out the method and carry out the one that suits you the best.

Why We Need to Download Emails from IMAP Server?

The IMAP is designed to keep emails synced across devices by storing them on a remote server. There are some compelling reasons to download emails as a local copy from the IMAP server.

  • Backup and Archiving: When we rely solely on the server for the data, it is risky. Anything could happen, such as Server issues, account suspension or accidental deletion that could lead to permanent data loss.
  • Offline Access: When you have a local copy of emails from the server, you can view, search and manage the email without the need for an internet connection.
  • Performance and Storage Managment: A Large mailbox can slow down the email client. After downloading and deleting the emails can free up server storage space, and thus lead to faster synchronisation and improve the performance of the account.

Method 1: Use Desktop Email Client

The most straightforward method is using the Desktop email client. The method includes the configuration of Outlook or Thunderbird to download emails from IMAP server.

Step 1: Configure IMAP Account with Email Client

  1. Open email client(Outlook or Thunderbird).
  2. Go to the File menu in Outlook.
  3. The client will auto-detect the IMAP settings.
  4. If not, enter the server details manually.
  5. Incoming Mail Server: imap.gmail.com
    Port: 993
    Security: SSL/TLS

The client will begin synchronisation with the server, downloading all emails.

Step 2: Export Mailbox to Local File

After the synchronisation is complete and the email folders are in the email client, you can export instantly.

For MS Outlook:

  1. Go to File > Open & Export > Import/Export.use import export
  2. Select “Export to a file” and click Next.click on export to a file
  3. Choose “Outlook Data File(.pst)” and click Next.press next button
  4. Select the folder of emails you want to download.
  5. Click Next, choose the destination to save the *.pst file and click Finish.

For Mozilla Thunderbird

Since Thunderbird does not have a native export feature like Outlook.

Use the Add-on: It is the easiest way to use the third-party add-on. The “ImportExportTool NG” is the one.

  1. Right-click on the folder and select ImportExportTools NG > Export folder.
  2. Save the content in *.eml or *.mbox format.
