The worlds most accepted email client Microsoft Outlook permits the user to manage Emails, Calendar, Contacts, Journals, and Notes etc using outlook. It allows the users to have common mail boxes, scheduling of meeting, calendars and even public folders. Outlook stores backup copies of these files in a .pst file (Personal Folder File). As a result of some reasons some times you may not be able to open email archive in PST file. The archive folder may contain important email information that you required.
Compacting of PST file can lead to permanent deletion of items from .pst files, and the empty space is reclaimed. That means, the item is removed permanently when you compact a PST that often shrinks the PST by many megabytes. Outlook may start compacting the PST immediately and if the Deleted Items folder contained a lot of messages, which were of great importance and were deleted accidentally be deleted forever within a few minutes. Using Outlook repair tool, you can recover deleted PST file effectively.
Since compacting delete the emails and related data permanently, and it would be highly impossible to recover those deleted emails. So a regular Email backup will save your important mails and other information. The outlook email backup software creates back up of all your emails, contacts, calendar, tasks, RSS feeds, emails settings, journal entries, and email signatures. The smart email backups avoid unexpected data loss from PST and you can even schedule your backup process using the internal scheduler feature.
