Migrating Outlook 2013 PST data to Outlook 2016 is typical task while you are using a manual method. Manual methods of migrating data from Outlook 2013 to 2016 is explained later before I will explain what are PST files and Why you need to migrate.

What are PST Files?

A PST file is Personal Folder file in Microsoft Outlook. It is an open proprietary file format used to store copies of messages, calendar events, and other items within Microsoft software such as Microsoft Exchange server, Windows Messaging and MS Outlook. These PST files are originally shipped with the MS Outlook and are used to access Exchange server mailboxes.

Why You Need to Migrate Outlook 2013 PST Data to Outlook 2016

It has been observed that storing data in PST files are not reliable so you have to move your PST data to another Outlook version. So, here I will discuss some of the reasons why you need to migrate.

  1. It’s very difficult to back up PST files.
    PST files are typically stores at hard drives and user does not prefer to back up those hard drives. In case if user needs to do back up of PST file then he avoids to back up hard drives.
  2. PST files get corrupted easily.
    As it has been known that PST file has a size limit of 2GB but in case if the size is exceeds, then it will leads to PST file corruption.
  3. Network Connected PST are not supported.
    In the above reason I have mentioned that PST files are basically stores at hard drives or removable devices which are very difficult to backed up hence Microsoft does not support network connected PST to be backed up. If PST files are on shared on network then they are not been backed up.
  4. PST files are limited as they only work for Outlook.
    There is one more disadvantage of PST files is it has limitation to use as it is only workable on MS Outlook. No, other Email client is able to access PST files.
