Prominent Reasons to Break Files

MS Outlook saves emails and other information in PST files, which are growing in size. Previously, there was a size restriction placed on PST files in general. Hence, the maximum size restriction in MS Outlook 2000 and 2002 was set to 2 GB. Outlook 2003 and 2007 had a limit of 20GB, however, with the launch of versions 2010 and 2013, the limit has been increased to 50GB+ expendable. Later on, the default PST file size limit in Outlook 2016 is 50GB, which may be expanded to 4 PB (4000 TB).

This is the reason if a user is currently using MS Outlook 2002, which has a maximum storage capacity of 2GB, that user will need to split archive PST into smaller files at regular intervals. The same goes with 2003 and 2007 Outlook versions of PST files, which enable a maximum size of 20 GB, resulting in a performance issue in Outlook.

It is difficult to handle big Outlook PST files since they slow down MS Outlook’s performance. So, users need to break the oversized PST file into smaller portions to avoid this sort of problem in the future.

Sending/receiving activities on a large-sized PST file might also be time-consuming. It is necessary to divide a huge Outlook PST file into smaller chunks.
