In short: You can back up Outlook e-mail in two ways: export a .pst file to your computer with Outlook’s Export feature, or use an e-mail archiving/backup service that automatically stores incoming and sent mail in the cloud. Cloud backup protects you from hardware failure, reinstallation and deleted messages.
Method 1: back up to a .pst file in Outlook
- In classic Outlook go to File > Open & Export > Import/Export.
- Choose Export to a file > Outlook Data File (.pst).
- Select the account or folder and tick “Include subfolders”.
- Save the file to an external drive or another safe location.
This is manual; mail received after the last export is not protected.
Method 2: automatic cloud e-mail backup
- Incoming and sent mail is archived automatically on the server side – no software to install.
- Mail can be restored even if the computer is replaced, reinstalled or messages are deleted.
- Works for company e-mail and for Gmail, Outlook.com/Hotmail, Yahoo and Yandex accounts.
- Search the archive and find old correspondence years later.
- Daily automatic backup; restore with one click to Outlook, Gmail or any mail client.
- Mail is fetched over SSL/TLS and stored with 256-bit encryption.
- Access your backups even if the mailbox is closed.
