Outlook Data file (PST) has several limitations like 2 GB file size limit in earlier versions which has become one of the major reasons of PST file corruption. Working in Outlook for months increases the size of PST file, and user don't remember to create a backup of the file, which ultimately leads to corruption of files. So keeping in mind the above problem, Microsoft has increased the default size of PST file up to 20 GB in its upgraded versions. But still files get corrupted as user while working in Outlook forgets about these limitations.
And when your PST file is about to reach 2 GB limit, some problems can be observed like your Outlook, will start running slow, or problems will be faced while receiving and sending the mails, etc. To overcome such problems, we have contributed to make a tool that can repair 2GB PST file.
