Backing up your emails locally ensures you never lose important messages. Here’s how to do it in major mail clients:

Microsoft Outlook

  1. Click File > Open & Export > Import/Export
  2. Choose Export to a file > Outlook Data File (.pst)
  3. Select the email account and folders to export
  4. Click Finish to save

Thunderbird

  1. Install the ImportExportTools NG add-on
  2. Right-click your inbox > ImportExportTools NG > Export all messages
  3. Select destination folder to save

Reminder: Backups are local and won’t protect against PC failure. Also consider server-level backups.
