The Need to Backup Entire Outlook Mailbox

If you are relying on email to get your work done, backing up entire Outlook mailbox or individual or multiple emails becomes an urgent need. Here are two main reasons:

  • First, Outlook contains all valuable data of your company, such as emails, attachments, calendars, contacts, notes, tasks, etc.
  • Second, backing up all emails in Outlook helps to prevent unexpected losses due to file corruption, deletion, malfunctioning hardware, system crashes, malware, etc.

Except for protecting data, you may want to backup all emails from one email account to another email account, for example, from 365 account to Gmail, or from PC to PC.
