The main reason behind PST corruption is the size limitation of PST file. If you’re using an older version of Outlook, i.e. 2002 and earlier, the PST file is saved in ANSI format. ANSI PST file has a size limitation of 2 GB, which means it can’t store more than 2 GB of mailbox data. If we talk about the newer version of Outlook, i.e. 2003 and later, Unicode format is used to save the PST file. Unicode PST file has a size limitation of 20 GB to 50 GB, which means you can store as much data as you want because 50 GB size is more than enough. Now let’s find out how corruption takes place in PST file due to size limitation issue. Think you’re using an old Outlook version, i.e. 2002. Your Outlook data file is saved in ANSI format. If the mailbox size reaches 2 GB, it will start causing serious problems and issues. Your Outlook client will start hanging, crashing frequently, and you will also notice poor Outlook performance.
